Everything You Need To Know About Keratoconus

Woman with KeratoconusIf you’ve been diagnosed with keratoconus, our Edmonton eye doctors understand your challenge and are here to help you see clearly and comfortably.

Below are some of the most commonly asked questions to help you gain a better understanding of what keratoconus is and how it can be treated.

What is Keratoconus?

Keratoconus affects about 1 in every 2,000 people. This progressive eye disease impacts the shape of the cornea, weakening it and causing it to thin and bulge outward into a cone shape.

The cornea is the clear, dome-shaped outer covering of the eye. It’s responsible for focusing incoming light onto the retina at the back of the eye to enable clear vision. So, when keratoconus develops, the change in the cornea’s shape directly impacts the way light is focused.

Keratoconus often results in nearsightedness and high levels of astigmatism — two refractive errors that cause blurry and distorted vision.

If left untreated, keratoconus can lead to permanent corneal damage and even loss of vision.

What Typically Causes Keratoconus?

Keratoconus develops when the collagen fibers that support the cornea begin to weaken. While having a family member with the disease is a significant risk factor, the following conditions can also lead to keratoconus:

  • Eye trauma
  • Eye allergies
  • Excessive eye rubbing
  • Certain eye diseases
  • Marfan syndrome
  • Ehlers-Danlos syndrome
  • Down syndrome
  • Osteogenesis imperfecta
  • Addison’s disease
  • Leber’s congenital amaurosis

The Signs & Symptoms of Keratoconus

The symptoms of keratoconus include:

  • Blurry vision
  • Distorted vision, with straight lines appearing bent or wavy
  • Sensitivity to bright light and glare
  • Red and irritated eyes
  • Increasing difficulty wearing standard contact lenses

Keratoconus tends to be initially detected in teens or young adults in their 20s, but symptoms can develop at any age.

Keratoconus symptoms usually start out mild but grow progressively worse over time — often over a decade or two — until the condition plateaus.

Both eyes are usually affected, and it’s common to have a difference in optical prescriptions between each eye.

Can Keratoconus Cause Vision Loss?

Keratoconus progression causes nearsightedness, astigmatism and visual distortions to worsen.

Eventually, corneal swelling can lead to scarring of the corneal tissue, which diminishes its transparency and increases your risk of vision loss.

Early detection and treatment of this condition are therefore critical for preventing permanent vision loss.

Can Keratoconus Be Corrected?

Initially, blurry and distorted vision can be corrected with custom-fit soft contact lenses or eyeglasses. However, as the condition progresses and your cornea becomes increasingly cone-shaped, these standard methods of vision correction become less effective.

At this point, many patients with mild to moderate keratoconus opt for scleral lenses, an effective, non-surgical method of achieving clear vision.

Severe keratoconus may require a corneal transplant procedure to replace your damaged cornea with a healthy donor cornea.

Scleral Lenses for Keratoconus

Custom designed scleral lenses help patients with corneal irregularities achieve dramatic improvements in visual acuity and comfort. Scleral lenses vault over the cornea and rest on the sclera while avoiding the diseased cornea. This creates a new optical surface instead of the damaged cornea and prevents discomfort by resting on the sclera of the eye. Moreover, the reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment – making it optimal for healing.

Don’t let keratoconus impact your quality of life. We can help you achieve clear, comfortable vision with scleral contact lenses.

If you or a loved one has been diagnosed with keratoconus, call Thompson Optics today to schedule a scleral lens consultation.

Our practice serves patients from Edmonton, St. Albert, Spruce Grove, and Leduc, Alberta and surrounding communities.

 

Frequently Asked Questions with Dr. Moe Tarabey

Q: What Are the Advantages of Wearing Scleral Lenses?

A: Below are the main benefits of wearing scleral lenses:

  • Scleral lenses are made of high-quality materials, which means they’ll last for the long haul.
  • Their large [size] enables them to stay centered and stable on your eye.
  • The vaulted lens holds hydrating saline solution which creates optimal conditions for ultimate comfort and healing of dry eyes.
  • Because the scleral lenses cover more surface of the eye than traditional lenses, they also help shield the eyes from external irritants.

Q: Are scleral lenses covered by insurance?

A: When it comes to scleral lenses, every insurance company is different. We recommend contacting us or checking with your insurance provider to find out if scleral lenses are covered under your plan.

Can Cataract Surgery Prevent Dementia?

Cataract surgery is a highly successful procedure that removes cataracts, the cloudy formations on the eye’s lens that impair vision.

Now, researchers are discovering that vision loss may be linked to a higher rate of dementia and suggest that restoring clear vision (through cataract surgery, for example) may reduce the risk of developing dementia.

Is There a Correlation Between Cataracts and Dementia?

More than half of those 80 or older have had at least one cataract. Many people in this age range also have dementia, a decline in cognitive functioning.

But is there a connection between these two seemingly unrelated conditions?

Recent studies suggest that, yes, there could be a link. One 15-year study found that patients with age-related vision problems, including cataracts, had a higher incidence of dementia.

The 2021 study, published in the British Journal of Ophthalmology, followed 12,000 subjects aged 55-73. When compared to patients with healthy vision, cataract patients had an 11% higher incidence of dementia.

Can Cataract Surgery Prevent Dementia?

Can sight-saving cataract surgery reduce your risk of dementia? It certainly looks promising!

A 2022 study published in JAMA Internal Medicine found that removing cataracts was “significantly associated with a lower risk of dementia development.” In fact, patients who had undergone cataract surgery had a 29% lower rate of dementia.

In addition, MRI scans have shown greater brain activity following cataract surgery.

How Can Vision Loss Cause Dementia?

Scientists studying the link between vision loss and dementia suspect that vision loss negatively impacts the brain. They theorize that the more visual information we receive, the more active our brains are, and brain activity may be able to fend off dementia.

For this reason, by restoring clear vision, cataract surgery may stimulate the brain and prevent cognitive decline.

There could be an emotional and social dimension to cognitive decline as well. People who suffer from significant vision loss often feel isolated. They may feel discouraged by their inability to recognize faces or perform everyday tasks, and may avoid social interactions. According to the Centers for Disease Control, social isolation raises the risk of developing dementia by 50%.

If you have cataracts and you feel your quality of life is affected, schedule an appointment with Thompson Optics in Edmonton without delay. We’ll answer your questions about cataract surgery and ensure you receive optimal treatment.

Q&A With Our Optometrist

How is cataract surgery performed?

Cataract surgery is a short 30-40 minute procedure that replaces your cloudy, natural lens with a synthetic intraocular lens (IOL). First, the eye surgeon makes a hole in the cloudy lens and breaks it into tiny pieces. Next, the eye surgeon places the new clear lens onto the eye. You’ll be conscious throughout the surgery. The surgery is safe, effective and painless.

Is cataract surgery always successful?

Cataract surgery is highly successful, with a 99% success rate. Complications from cataract surgery are very rare.

Can We Stop Myopia From Progressing?

boy and a girl with myopiaIf you think more powerful prescription glasses are the right solution to keep your child’s myopia from getting worse, think again. Talk to us about myopia management, which can slow the progression of myopia (nearsightedness) by up to 78%.

How Does Myopia Worsen?

In nearsighted people, the cornea, the clear outer layer of the eye, is more curved than in non-myopes. This elongated eyeball shape refracts incoming light in front of the retina rather than directly on it. The result? Blurred vision.

In other words, the longer the eyeball, the more severe the myopia.

The following can contribute to myopia progression:

  • Eye growth – as children grow, so do the eyeballs. And in certain cases, they become elongated (myopia).
  • Hereditary factors – if one or both parents have myopia, the condition is likely to progress at a rapid pace.
  • Not enough outdoor time –1 to 2 hours a day outdoors is recommended to prevent myopia progression.
  • Excessive screen time – myopia development and progression have been linked to extended screen time.

What Is Myopia Management?

Myopia management is a custom-designed treatment plan that identifies slows or stops myopia progression. Our optometrists provide diagnostic eye exams and create a myopia management program to keep your child’s nearsightedness in check.

Why Is Myopia Management Important?

Myopia doesn’t just affect your child’s ability to see distant objects; it can increase your child’s risk of developing these serious eye problems in adulthood:

  • Glaucoma
  • Cataracts
  • Myopia macular degeneration
  • Retinal detachment

The sooner your child begins myopia management, the better the chances of slowing myopia’s progression and reducing the risk of eye diseases later in life.

Myopia Management Can Preserve Your Child’s Vision

If you’re eager to preserve your child’s eyesight now and in the future, myopia management can help. Book an appointment at Thompson Optics today!

Our practice serves patients from Edmonton, St. Albert, Spruce Grove, and Leduc, Alberta and surrounding communities.

Frequently Asked Questions with Dr. Moe Tarabey

Q: Does screen time affect myopia?

  • A: Yes. In a study published in The Lancet Digital Health (October 2021), an international team of researchers found that at least 3 hours of screen time per day can increase the risk of developing myopia by 30%. Other research suggests that reducing your child’s screen time and encouraging more outdoor activities can prevent myopia and keep it from progressing.

Q: When should one start myopia management?

A: As soon as possible! Research shows that the earlier a child becomes myopic, the faster their myopia will progress. Act quickly if you want to have the greatest impact on slowing myopia progression.

June 27 Is National Sunglasses Day!

Monday, Jun 27, 2022 is National Sunglasses Day, so grab your favorite pair of sunnies and celebrate!

Many people think sunglasses are little more than a fashion accessory or a way to minimize glare while driving.

But the truth is that wearing sunglasses is vital if you want to safeguard your eye health and vision.

Why Sunglasses are Important

The number one reason to wear sunglasses is that they prevent ultraviolet (UV) light from entering your eyes.

UV light has been shown to age every part of the eye, from the delicate outer eye tissue to the tiny structures within the eye itself. Chronic UV exposure raises your risk of developing cataracts, age-related macular degeneration and corneal damage.

The skin on your eyelids is the thinnest skin of your body, and UV light exposure can further thin eyelid skin, leading to premature aging and the appearance of dark circles and under-eye bags. Additionally, wearing sunglasses can help prevent wrinkles because you’ll squint less in the sunshine. Who knew sunglasses can be a key player in your anti-aging routine?

Moreover, UV light has been shown to slow the cornea’s ability to heal itself, making sunglasses a medical necessity for people who’ve recently had eye surgery like LASIK, or those who frequently wear contacts (overwearing contacts can irritate the cornea).

Finally, sunglasses are a fun way to show the world your personality and accessorize any outfit.

Activities for National Sunglasses Day

Not sure how to celebrate National Sunglasses Day? Here are a few ideas you may enjoy.

Sport your favorite pair of sunglasses during an outdoor activity, whether it’s a barbecue with friends, a concert at a stadium or time spent in the park.

You can also celebrate National Sunglasses Day by gifting a pair of quality sunglasses to a friend, spouse or child!

No matter how you choose to celebrate National Sunglasses Day, we hope you enjoy and keep your eyes protected.

For all matters related to eye health, ​​Thompson Optics in Edmonton is here for you. Contact our eye doctor today!

FAQ With Our Optometrist

Should kids wear sunglasses?

Yes, children of all ages should wear sunglasses whenever they’re outdoors. In fact, it’s crucial because a child’s crystalline lens within the eye is much more clear than an adult’s, letting more light through. Contact us to learn more about kids’ eye health or to schedule an eye exam.

Can sunglasses block blue light?

Sunglasses with lenses that have a yellowish tint offer the most amount of blue light protection, from the sun and other sources. If you’re interested in blocking the blue light that’s emitted from your digital devices, speak with us to determine if computer glasses are right for you.

4 Facts You Should Know About Scleral Lenses

Woman wearing Scleral Lenses scenic viewDo you have keratoconus or another type of corneal irregularity due to a medical condition or post-surgical complications? Are you considering giving up conventional contacts due to dry eye syndrome?

Consider scleral contact lenses! Contact Thompson Optics in Edmonton to learn more and to discover a new sense of freedom with sclerals!

What Are Scleral Contact Lenses?

Sclerals are customized rigid gas permeable lenses that are wider than conventional lenses. Their name reflects the fact that they vault over the cornea and rest on the sclera, the white part of the eye.

Scleral contact lenses are 14-24 mm in diameter, while regular contacts are 9mm. This gives sclerals room to accommodate irregularly shaped corneas and provides a reservoir of moisture to soothe dry eyes.

4 Essential Facts About Scleral Contact Lenses

1. Sclerals Are the Right Fit for Irregularly Shaped Corneas

Keratoconus, astigmatism and complications from eye surgery can all result in an irregular-shaped cornea, and wearing contact lenses when your eyes are hard to fit can be challenging. Because sclerals are larger than regular contacts and don’t sit on the sensitive cornea, they provide lots of space and a comfortable fit.

2. Scleral Contact Lenses Can Reduce Dry Eye Symptoms

If you have dry eye syndrome, you may be tempted to give up on wearing contacts altogether. Scleral lenses are ideal for people with dry, itchy and irritated eyes. A lubricating pool of saline solution inside each scleral lens can reduce or even eliminate dry eye discomfort.

3. Sclerals Create a Wider Field of Vision

The width of sclerals not only makes them more comfortable but can extend your field of vision. Their diameter can expand your optic zone and make your peripheral vision sharper and clearer.

4. Sclerals Are Durable and Long-Lasting

Rigid gas permeable contact lenses, including scleral lenses, last longer than conventional soft contacts. Their durable materials are designed to resist wear and tear, which is also why scleral lenses don’t require frequent replacements.

Enjoy the convenience and clear vision scleral lenses by scheduling an appointment with Thompson Optics and discover whether scleral lenses are the right choice for you.

Our practice serves patients from Edmonton, St. Albert, Spruce Grove, and Leduc, Alberta and surrounding communities.

 

Frequently Asked Questions with Dr. Moe Tarabey

Q: Can I exercise with scleral lenses?

  • A: Scleral lenses are ideal for people who lead active lives—whether you’re a professional athlete or just like to pass a ball around with friends at the park. Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. That said, scleral lenses aren’t recommended for martial arts and other sports with a higher-than-usual rate of facial injuries.

Q: If I have keratoconus, can I avoid corneal surgery with scleral lenses?

  • A: A study published in the Journal of Ophthalmology (2018) that examined 51 patients with advanced keratoconus found that 40 of them didn’t need surgery after wearing scleral lenses. In fact, wearing them reduced the need for corneal transplant or keratoplasty by half during a 5-year period.

Could Working From Home Be Hurting Your Vision?

Working at home is a great way to ditch your commute and enjoy more flexible hours, but there can be an unexpected consequence—digital eye strain. If you’re like many workers, you probably spend most of your day on a computer or other digital device, and likely experience the headache, blurred vision, sore eyes or achy back so common with digital (computer) eye strain.

In contrast to being in the office, where workers take coffee breaks and socialize, working solo at home often translates into spending more time on the computer without breaks, and often beyond the typical 9 to 5 schedule. This can increase the likelihood of developing digital eye strain.

What Is Digital Eye Strain?

Digital eye strain, also called computer vision syndrome (CVS), affects an estimated 70% of adults, especially those between the ages of 18 and 34.The eye strain results from extended hours focusing on a computer screen, and may be worsened by hours of exposure to blue light, high-energy visible light emitted by digital screens.

Blue light can cause short-term eye strain and discomfort, and scientists are researching whether it could also be linked to serious eye conditions, such as age-related macular degeneration (AMD) and cataracts.

Moreover, staring at a screen, or even a printed book, causes people to blink up to 66% less often. Blinking is essential as it hydrates your eyes and stimulates the release of oil from the tiny glands in your eyelids. This oil also prevents tears from evaporating too quickly, thus drying out the eyes. Dry eyes can cause blurry vision, which further exacerbates eye strain.

What Are the Symptoms of Digital Eye Strain?

The following are common symptoms of digital eye strain:

  • Blurry vision
  • Eye soreness
  • Headaches Dry eyes
  • Light sensitivity
  • Neck, back and shoulder pain

How Can I Prevent Digital Eye Strain?

No need to ditch your job in order to avoid eye strain. There are other, more practical, ways to lessen the negative impact of screen time on our eyes. Below are some helpful tips.

Take Breaks

Even if you aren’t at the office and may not have co-workers to hang out with at the coffee machine or water cooler, make sure to take frequent breaks that don’t require screen time. Perhaps take a walk or reward yourself with a short nap. These breaks not only give your eyes a rest, but can rest your mind for a few minutes so you can work more efficiently.

Consider adopting the 20/20/20 habit. For every 20 minutes you spend in front of a screen, take a 20-second break and look at something 20 feet away. This will prevent you from overstraining your eyes and will encourage you to blink more, providing your eyes with much-needed hydration.

Adjust Screen Brightness

Bright screens can place a significant burden on your eyes. Simply adjusting your screen’s brightness can help rest your eyes.

See Your Eye Doctor

If you spend prolonged periods in front of the screen, it’s important to schedule an eye exam with your eye doctor to discuss whether you would benefit from lubricating eye drops or a pair of computer glasses. These computer glasses (or blue light glasses) allow your eyes to relax and make you feel as if you’re focusing on faraway objects. They also reduce glare and filter out blue light.

Whether you’re suffering from any of the symptoms related to digital eye strain or simply want to prevent it, we invite you to book an appointment with Thompson Optics in Edmonton. With the right eye care and work habits, you should be able to successfully and quickly reduce and prevent eye strain.

Q&A With Our Optometrist

How long does it take to recover from computer eye strain?

If you don’t have an underlying eye condition, symptoms of digital eye strain can sometimes disappear within a few hours or days. But if you have recurrent eye strain, speak with your eye doctor, as the right eye drops or computer glasses could improve your visual comfort and quality of life.

Can digital eye strain affect my work productivity?

You may think spending hours in front of a computer screen will improve your productivity, when in reality, it may have the opposite effect. According to a study at the University of Alabama/Birmingham School of Optometry, even minor vision problems, such as eye strain, disrupt worker productivity by at least 20%.

So make sure to take steps to control lighting and glare on the device screen and establish proper working distances and posture for screen viewing. To learn more and to alleviate or prevent eye strain, contact Thompson Optics today.

How Myopia (Nearsightedness) Can Affect Your Child’s Life

child in school unable to work due to myopiaMyopia (also known as nearsightedness) is nothing short of a global epidemic. According to the World Health Organization, 27% of the world’s population has myopia, and that number is expected to rise to 50% by 2050.

Myopia almost always begins in childhood and can progress rapidly until the late teens or early twenties. Children with moderate or severe myopia are at a much greater risk of developing eye conditions that can cause vision loss and even blindness.

Fortunately, there are proven ways to slow and sometimes halt myopia’s progression during childhood, to safeguard your child’s vision for a lifetime.

What Causes Myopia?

Myopia is often inherited, but other risk factors include spending too many hours indoors engaged in ‘near work’ like reading and staring at electronic screens.

Myopia occurs when the eyeball grows longer, which causes light rays to refract incorrectly, focusing images in front of your retina instead of on your retina. This results in blurry vision.

How Myopia Can Impact Your Child

Nearsightedness can affect your child in many ways:

Difficulties at School and While Playing Sports

Sometimes parents don’t realize their child is experiencing myopia-related blurry vision until they notice a recurrence of poor grades on their report cards or tests.

Eyestrain

Trying to focus on faraway objects to see them with more clarity when they appear blurry often results in eyestrain. Yet many parents and teachers don’t realize that a child’s headaches, tired, burning, itchy eyes, blurry vision, neck and shoulder pain may be caused by myopia.

Poor Sports Performance

When you try to catch a ball, aim for a target or locate a goal post, you need to see clearly at a distance. Nearsightedness can interfere with a child’s ability to succeed on the sports field.

How Does Myopia Affect Quality of Life?

Myopia isn’t just about difficulty seeing faraway objects. Rapidly progressing myopia increases a child’s risk of developing serious eye conditions in the future. They include:

  • Glaucoma
  • Retinal detachment
  • Cataracts
  • Myopic maculopathy

What is Myopia Management?

Myopia management is the area of optometry devoted to slowing down and even halting the rapid progression of myopia in childhood. Myopia can be managed thanks to a customized treatment program provided by an eye doctor near you. The sooner a child’s myopia is managed, the lower the risk of myopia-related complications in adulthood.

To find out how myopia management can transform your child’s vision, confidence and success in life, schedule an appointment with our optometrists today.

Our practice serves patients from Edmonton, St. Albert, Spruce Grove, and Leduc, Alberta and surrounding communities.
Frequently Asked Questions with Dr. Moe Tarabey

Q: Can Myopia Be Cured?

  • A: While there’s no cure for myopia, myopia management has been scientifically proven to slow and at times halt myopia’s progression. LASIK and other laser surgeries aren’t an option until a child with myopia reaches adulthood and their eyes have stopped growing (meaning, their eye prescription has stopped changing).

Q: What is High Myopia?

  • A: High myopia is a more severe form of regular myopia, usually above -3.00 dioptres. Children who develop high myopia often have rapidly progressing myopia that begins in early childhood and are at a higher risk of developing serious sight-threatening eye diseases later in life, such as glaucoma, macular degeneration and cataracts. Myopia management can help slow or halt the rapid progression of myopia, offering the child a higher quality of life in the long term.

    What Exactly is an Eye Chart?

    If there’s one aspect of optometry that everyone recognizes, it’s the traditional eye chart, with its rows of big letters on top, which gradually become smaller the farther down you go. This chart is usually known as the Snellen chart.

    Yet how much do you really know about this eye chart? Are all eye charts the same? How are these eye charts used? And when were they invented?

    Here’s everything you need to know about eye charts and more!

    What is an Eye Chart?

    An eye chart is one of the tools your eye doctor uses to assess your eyesight. Based on how well you can see various letters on the chart, your optometrist will determine whether you have myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age-related farsightedness) or astigmatism, and will measure the prescription that will give you the clearest, most comfortable vision.

    Are All Eye Charts The Same?

    There are a number of variations to the standard Snellen eye chart. The one an eye doctor uses depends on the personal needs and abilities of the patient. For example, eye doctors will use charts with pictures or patterns for younger children who may not have learned to read or identify letters and numbers.

    There are also certain charts that specifically measure distance vision, while others are better for measuring near vision.

    History of the Snellen Eye Chart

    The Snellen eye chart was developed by Dutch eye doctor Hermann Snellen in the 1860s. Before this standardized eye chart was developed, each eye doctor had their own chart that they preferred to use.

    Having so many different eye charts made it impossible to standardize the vision correction available to patients. Eyeglass makers didn’t receive the defined measurements they needed to accurately design, manufacture and measure the optical prescriptions their patients needed.

    For the first time, the Snellen eye chart allowed a person to provide a standardized prescription from any eye care provider they chose to any eyeglass maker, and get the same optical lenses to accurately correct their vision.

    How The Snellen Chart Is Used in Eye Exams

    The standard Snellen chart displays 11 rows of capital letters, with the first row consisting of a single large letter. The farther down the chart you go, the smaller the letters become.

    Your Edmonton eye doctor will ask you to look through a phoropter – an instrument used to test individual lenses on each eye during an eye exam – and look at the Snellen chart placed 20 feet away. Your eye doctor will prescribe the lenses that provide you with the clearest and most comfortable vision.

    In many offices, where 20 feet of space may not be available, you’ll be asked to view the chart through a mirror. This provides the same visual experience as if you were standing 20 feet away.

    If you have 20/20 vision, it means you can see what an average person can see on an eye chart from a distance of 20 feet. On the other hand, if you have 20/40 vision, it means you can only see clearly from 20 feet away what a person with perfect vision can see clearly from 40 feet away.

    If you have 20/200 vision, the legal definition of blindness, this means what a person with perfect vision can see from 200 feet away, you can see from 20 feet away.

    Does 20/20 Visual Acuity Mean Perfect Vision?

    No. While eye chart tests identify refractive errors, they can’t detect signs of visual skill deficiencies or diseases such as glaucoma, cataracts or macular degeneration. These are diagnosed using advanced equipment as part of a comprehensive eye exam with your local Edmonton eye doctor. Early diagnosis and treatment of eye conditions are essential to ensuring long-term vision and eye health.

    Q&A With Your Local Optometrist

    How do you keep your eyes healthy?

    You only have one set of eyes – don’t take them for granted!

    Make sure to implement the following habits for healthy eyes (and body). These include:

    • Eating a balanced diet rich in fiber, fruits and vegetables
    • Drinking plenty of water to hydrate your body and eyes
    • Not smoking, and avoiding 2nd-hand smoke
    • Wearing sunglasses to protect your eyes from ultraviolet (UV) rays
    • Maintaining normal BMI with regular exercise
    • Regular visits to your eye doctor as recommended

    What health conditions can an eye exam detect?

    A comprehensive eye exam can often detect certain underlying diseases that can threaten your sight and eye health, such as diabetes, high blood pressure, high cholesterol, tumors, autoimmune conditions and thyroid disorders. This is why having your eyes checked regularly is key. The earlier the diagnosis and treatment, the better the outcome and the higher your quality of life.

    Bloodshot Eyes – Should You Be Concerned?

    You wake up in the morning ready to start your day, only to discover that your eyes are bloodshot. That might not be surprising if you stayed up late to finish a project, had too many drinks at a party or spent time in a smoke-filled room.

    But bloodshot eyes can also signal an underlying eye problem. If your eyes appear red or bloodshot, make an appointment with an eye doctor for a comprehensive eye exam to determine the cause and to receive effective treatment.

    Why Do I Have Bloodshot Eyes?

    When blood rushes to the front of the eye, the tiny red blood vessels on the white of the eye dilate and become visible. This makes the eyes appear red and irritated.

    So why do these blood vessels dilate, causing your eyes to look bloodshot?

    Bloodshot eyes tend to be caused by:

    • Dry eyes
    • Irritants such as smoke, pollen and perfume
    • Lack of sleep
    • Excessive alcohol consumption
    • Spending too much time in front of the computer

    Bloodshot eyes due to lifestyle and environmental irritants may disappear on their own, or you can try to relieve them with over-the-counter eye drops or liquid tears. Lifestyle changes, such as getting more sleep, cutting down on alcohol intake and limiting screen time can often be helpful. If allergies are the culprit, oral antihistamines and antihistamine eye drops may relieve symptoms.

    At other times, underlying problems requiring prompt medical attention can cause your eye’s blood vessels to dilate. The following are some of these medical conditions:

    Conjunctivitis

    You’ve probably heard of “pink eye.” It’s another name for infectious conjunctivitis – an infection of the conjunctiva, the thin membrane covering the eyelid and the front surface of the eye.

    There are two types of infectious conjunctivitis – bacterial and viral.

    If your child has conjunctivitis, they’re not alone. About 12% of kids get bacterial conjunctivitis every year. This highly contagious condition affects children and adults. In addition to reddish eyes, the following symptoms are associated with conjunctivitis:

    • Bacterial conjunctivitis – irritated eyes, swollen eyelids, eye discharge, crusty eyelids and excessive tearing
    • Viral conjunctivitis – cold or flu-like symptoms, runny nose, fever, itchy eyes, excessive tearing

    If you or your child are experiencing these symptoms, it’s important to schedule a prompt appointment with an eye doctor, who can diagnose whether the conjunctivitis is viral, bacterial or due to allergies.

    Depending on the diagnosis, your eye doctor will prescribe antibiotic eye drops or creams to treat bacterial conjunctivitis. The viral form may run its course after a few days, but cold compresses and non-prescription eye drops may provide relief.

    Dry Eye Syndrome

    If your eyes are chronically bloodshot you may have dry eye syndrome (DES). Signs of DES include:

    • Dry, irritated eyes
    • Burning or stinging eyes
    • Discharge from the eyes
    • Light sensitivity
    • A feeling you have something stuck in your eyes
    • Blurred vision
    • Watery eyes

    Dry eye syndrome is most commonly caused by a blockage of the tiny meibomian glands in the eyelids. These glands secrete oil that keeps eye moisture from evaporating too quickly. Without the oil, tears dry fast, leaving your eyes feeling dry, itchy and with a bloodshot appearance.

    Too much screen time, aging, certain medications such as antihistamines, and medical conditions such as Sjogren’s syndrome can cause dry eye syndrome.

    In addition to any medications or in-office treatments your eye doctor recommends, make sure to get plenty of hydration, take frequent breaks from digital screens and use a humidifier in your home.

    Uveitis

    In addition to bloodshot eyes, if you also experience blurred vision, see floaters or your eyes feel painful, you may have an eye inflammation called uveitis. The causes of uveitis include:

    • Autoimmune or inflammatory condition
    • Infection
    • Medication side effects
    • Cancer (in rare cases)

    Unfortunately, uveitis symptoms can often be mistaken for something less serious. That’s the reason it’s important to get an eye exam if your eyes are bloodshot. Left untreated, uveitis can lead to serious conditions such as retinal scarring, cataracts and vision loss.

    Depending on the cause and severity, your eye doctor may treat uveitis with prescription eye drops, steroid pills, injections or eye implants.

    Eye Injury

    It’s vital that all eye injuries receive immediate eye care from an eye doctor.

    Even a minor eye injury can cause a big red blotch to form on the white part of the eye (sclera). The cause is a broken blood vessel or a subconjunctival hemorrhage.

    Although the appearance of this blood looks severe, and can make the entire white part of the eye appear bright red, a subconjunctival hemorrhage is usually painless and doesn’t cause vision loss. Any time you notice excessive blood on the eye following an eye injury, schedule an appointment with an eye doctor to assess the health of your eye.

    Glaucoma

    In rare cases, bloodshot eyes may signal the presence of glaucoma – a leading cause of vision loss and blindness.

    While some types of glaucoma don’t show symptoms in the early phases, bloodshot eyes can indicate the type of glaucoma that requires immediate medical care. This disease causes damage to the optic nerve due to excessive pressure within the eye. When this pressure suddenly rises, the eye’s blood vessels become dilated and visible, making the eye appear red.

    If you have bloodshot eyes and/or have the following risk factors for glaucoma, immediately schedule an appointment with your eye doctor.

    • Family history of glaucoma
    • Aged 60+
    • African American, Asian or Hispanic
    • Diabetes
    • High blood pressure

    Q&A With Your Local Optometrist

    Can I get bloodshot eyes after LASIK surgery?

    LASIK surgery is highly effective minimally invasive laser eye surgery that can correct refractive errors, but like all surgical procedures, it can have side effects. Your eyes may be bloodshot or you could see halos from a few days to three weeks after surgery. Additionally, you may experience other dry eye symptoms. Eye drops and liquid tears can alleviate these symptoms, but if you have any concerns about your eyes following LASIK surgery contact your eye surgeon.

    What Should I Expect from a Glaucoma Exam?

    If you have a family history and/or other risk factors for glaucoma, and if your eyes look bloodshot, consider scheduling a glaucoma exam. Your eye doctor may perform the following tests:

    • Tonometry – eye pressure test
    • Gonioscopy – to see how fluid is draining out of your eye
    • Vision field test – to examine the functioning of the optic nerve
    • Dilated pupil exam – to detect any damage to the optic nerve
    • Retinal photo or OCT – digital examination of the retina and optic nerve health

    Are Myopic Parents More Likely to Have Myopic Children?

    Myopic Parents 640×350If you have myopia (nearsightedness), can you pass nearsightedness on to your children? Yes, you can. Having myopic parents greatly increases a child’s risk of developing myopia.

    Due to heredity and other risk factors, myopia is reaching epidemic proportions – with more than 50% of the population expected to be myopic by 2050. That’s worrying, as having moderate to severe myopia greatly increases the risk of developing sight-threatening eye diseases like glaucoma and macular degeneration later in life.

    What Is Myopia?

    If you have myopia, distant objects will appear blurred. This happens when your cornea or eye lens is oval-shaped and excessively curved. As a result, the light entering your eye focuses images in front of your retina instead of directly on it, causing blurred vision.

    Can Myopia Be Inherited? What the Stats Say

    The answer is yes, myopia can be passed on from parents to children. There are 40 genes that influence the eye’s development and shape, and these could be responsible for nearsightedness.

    Children with one myopic parent are 1.5x more likely to develop the condition, and the risk is tripled if both parents have myopia. This makes getting a comprehensive eye exam a must for any child of nearsighted parents.

    Other risk factors include spending less than two hours a day outdoors and engaging in “near work” activities like reading and spending time on an electronic device, such as a computer or cell phone. Fortunately, there are ways to manage, slow and sometimes halt myopia progression.

    What’s Myopia Management?

    Myopia management is a systematic approach to preventing the progression of myopia. It includes lifestyle changes and treatments that help keep your child’s myopia from progressing.

    Frequently Asked Questions with Dr. Moe Tarabey

    Q: What are some ways I can reduce my child’s screen time?

    • A: It isn’t easy to change habits, but as a family, you can work together to reduce screen time. Try the following:- Set limits on total amount of screen time per day
      – Create routines around screen use–such as after homework and chores
      – Model healthy screen use for your child
      – Talk to your children about why it is important to limit screen time
      – Engage in physical activity and outdoor sports as a family

    Q: When Does Myopia Typically Develop?

    • A: Myopia begins in children as young as 6 and tends to progress until roughly the age of 20. The more it progresses, and the higher the prescription, the greater your child’s risk of developing potentially sight-threatening eye conditions, such as cataracts, glaucoma, macular degeneration and retinal detachment later in life.
