Macular Degeneration

What’s The Link Between Obesity And Eye Disease?

People who are obese are at higher risk of developing some sight-threatening eye conditions and diseases. Read on to discover why, and how we can help.

It is well documented that obesity impacts health in numerous ways, from a higher incidence of diabetes to cardiovascular disease. What many people don’t know is obesity’s negative effect on vision and eye health. Speak with our Eye care professionals at KW NeuroVision about any concerns you may have about your eye health or vision.

There is increasing evidence that obese individuals have a greater risk of developing serious, sight-threatening eye diseases.

Researchers at the Goldschleger Eye Institute at the Sheba Medical Center found a consistent link between obesity and the development of age-related macular degeneration, cataracts, glaucoma, and diabetic retinopathy.

The researchers noted that the public is largely unaware of this link, despite the evidence. If more people knew about the risk, they said, it might motivate them to try to shed some extra weight.

How Does Obesity Impact The Eyes?

A body mass index (BMI) of 25-30 is considered overweight and any BMI over 30 is considered obese. Recent studies indicate that a handful of ocular diseases can now be added to the list of medical conditions associated with an elevated BMI.

Diabetic retinopathy, floppy eyelid syndrome, retinal vein occlusions, stroke-related vision loss, and age-related macular degeneration are all risk factors of obesity.

While the cause is not yet certain, researchers believe this may be due to the peripheral artery disease prevalent among people who are obese. When the tiny blood vessels around the eyes are compromised, they may have trouble delivering oxygen and other nutrients to the eye area.

Obesity is also a risk factor for developing cataracts (the clouding of the eye’s natural lens). Poor nutrition or high blood sugar levels, which are commonly found in people with obesity, may contribute to the cloudiness.

Although obesity may contribute to cataract formation, losing weight may not significantly reduce the risk of developing them, partly because cataracts are also a common consequence of aging, whatever one’s weight.

Additionally, morbid obesity is associated with higher inner eye pressure, which may increase one’s risk of glaucoma and glaucomatous optic neuropathy — leading causes of vision loss and blindness. Morbid obesity is defined as having a BMI of 40 or above, or 35 and above with health conditions like high blood pressure or diabetes.

Stay Active, Healthy, and Have Regular Eye Exams

An active lifestyle and a nutritious diet can help you maintain a healthy weight and improve overall physical and eye health. Try to include several key nutrients into your diets, such as vitamins C and E, zeaxanthin, omega-3, zinc, and lutein, as they may help delay or prevent certain eye diseases.

While a balanced diet and regular exercise significantly increase your chance of living a healthy life, it’s also crucial to have regular eye exams. A comprehensive eye exam with Dr. Howard Dolman can help detect the onset of ocular disease and ensure the earliest and most effective treatment to preserve your gift of sight.

Don’t hesitate to call Dolman Eyecare Centre in New Hamburg with any questions or concerns regarding your vision or eye health — we’re here for you.

  • Is it possible to prevent Macular Degeneration?

    Doctors aren’t sure how to prevent macular degeneration. Research suggests that ultraviolet light (and possibly blue light) factors into the problem, so sunglasses could be very beneficial.

  • My doctor says I have a cataract, but he wants to wait a while before removing it. Why?

    A cataract usually starts very small and practically unnoticeable but grows gradually larger and cloudier. Your doctor is probably waiting until the cataract interferes significantly with your vision and your lifestyle. You need to continue to visit your eye doctor regularly so the cataract’s progress is monitored. Some cataracts never really reach the stage where they should be removed. If your cataract is interfering with your vision to the point where it is unsafe to drive, or doing everyday tasks is difficult, then it’s time to discuss surgery with your doctor.

  • What exactly is glaucoma?

    Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

  • What is diabetic retinopathy?

    Doctors aren’t sure how to prevent macular degeneration. Research suggests that ultraviolet light (and possibly blue light) factors into the problem, so sunglasses could be very beneficial.

Exercise Helps Keep Your Eyes in Shape Too!

Dolman Eyecare Centre An Active Body is Linked to Healthy Eyes near you in New Hamburg, Ontario

You know all about how regular exercise strengthens your heart and lungs, as well as boosts your energy. Did you also know it can promote healthy vision? Remember, your body is one interconnected unit, and every organ benefits from getting a workout. Our Eye doctor near you in New Hamburg, Ontario explains how physical activity helps to preserve your quality vision.

The Importance of Preventive Health Care near you in New Hamburg, Ontario

A variety of scientific studies have confirmed that regular exercise can reduce the risks of common eye diseases, such as glaucoma, cataracts, and age-related macular degeneration. The effects of exercise on your quality of life are therefore far-reaching, helping to prevent visual impairment and blindness. Sharp vision is intricately connected to your physical and mental health, enabling you to work and enjoy all the activities you love to do.

When assessing risk factors for ocular disease, eye care providers focus on a holistic view of the person. Eye health can be related to your overall health, with conditions such as high blood pressure, high cholesterol, and diabetes being risk factors for vision loss.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Pink Eye or conjunctivitis, Myopia or Nearsightedness , Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Is LASIK eye and vision surgery an option for you ? Our New Hamburg eye doctor is always ready to answer your questions about eye disease and Contact lenses.

How Much Exercise Is Recommended?

At our eye clinic near you in New Hamburg, Ontario, patients constantly ask about the bottom line: how much is enough exercise to reap the eye health benefits? According to the American Academy of Ophthalmology, you don’t need to run a marathon. Leading an active lifestyle, such as taking brisk walks, climbing up the stairs instead of using the elevator, and dancing can have a positive impact on eye health. In many cases, these types of exercise are enough to help lower blood pressure and keep blood sugars in control, which in turn helps prevent vision damage.

The Importance of Preventive Health Care

  • Along with exercising and maintaining a healthy, nutritious diet, the team at our eye care center near you encourages everyone to follow these preventive tips to keep your vision healthy:
    Get routine eye exams so your eye doctor can inspect for any early signs of disease, which will allow you to receive treatment as early as possible. Early detection is essential for effective treatments to slow or prevent damage to your vision.
  • Know your family eye history and share the facts with your eye doctor.
  • Wear sunglasses whenever you’re outdoors, regardless of the season. Dangerous UV rays are always out there.
  • Don’t smoke; smoking increases your chances of developing age-related macular degeneration and cataracts.
  • Eat nutritiously, including fruits and vegetables and foods high in omega-3 fatty acids, such as salmon.

I see fine. Why do I need to see an Eye Doctor?

Regular eye exams are the only way to catch “silent” diseases such as diabetes, glaucoma, and other conditions in their early stages when they’re more easily managed or treated. Many conditions can be discovered in a carefully planned eye exam. Those who consider mass-produced, over-the-counter reading glasses are truly doing themselves a disservice, both financially and medically. One-size-fits-all reading glasses not only do not work well for most people who have a different prescription in each eye, and/or astigmatism, or whose lens and frame parameters are not measured correctly, they bypass the opportunity to have their eyes checked for early detection of many manageable diseases or conditions. For those insisting on selecting glasses not measured specifically for their eyes, headache and eye fatigue are common symptoms.

What are cataracts and how can they be treated?

Cataracts are a clouding of the lens inside the eye. They are common with age, certain medications, and medical conditions. Patients usually feel like they are looking through a dirty window, cannot see colors the way they used to, or have increased difficulty with glare. Currently, the treatment is surgery to remove the cloudy lens. Stay tuned for medical advances in cataract treatment in the future!

What exactly is glaucoma?

Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss.

Why You Regularly Need to Replace Your Sunglasses

Did you know that sunglasses, or at least sunglass lenses, regularly need to be replaced? 

According to a study conducted at the University of São Paulo, the UV protection that sunglasses provide deteriorates over time. You may adore your current ones, but if you’ve been rocking those shades for two or more years, it might be time to get a new pair. 

In addition to the UV-blocking properties, anti-reflective and anti-scratch coatings wear down, and the frame material may become brittle over the years, too. Even if you have the most durable sunglasses available, regular lens-replacement is the best way to ensure that your vision is maximally protected from the harmful effects of ultraviolet light. 

UV Light and Sunglasses

The protective efficacy of your sunglasses comes in large part from the lens coating of dyes and pigments that reflect and absorb ultraviolet radiation. They create a barrier that prevents UV radiation from penetrating your eyes.

However, this protective coating can, and often does, break down over time. Wear and tear can cause an invisible web of tiny abrasions, compromising its UV-blocking power. Furthermore, the protective dyes and pigments aren’t able to absorb UV rays indefinitely; the more sunlight they’re exposed to, the more rapidly they’ll become ineffective. 

A pair of shades worn on occasion and in mild conditions is likely to remain effective longer than a pair that is heavily used in a more intensely sunny environment. For example, if you spend long days on the water paddling, kayaking, or canoeing, the protective coating on your lenses will deteriorate more quickly than it would if you only wear your shades to go grocery shopping or sit in a cafe. 

Why It’s Important to Protect Your Eyes From UV

Protecting your eyes from the sun is critical no matter where in the world you are, as UV exposure places you at risk for developing eye diseases like eye cancer, pterygium, and pinguecula — which can result in disfigurement and discomfort — as well as cataracts and macular degeneration — which cause vision loss and, in severe cases, blindness.

Even short-term overexposure can result in photokeratitis, a corneal sunburn. Symptoms include eye pain, swelling, light sensitivity, and temporary vision loss. Some people experience it when spending too much time boating or skiing without wearing eye protection. Snow and water can increase solar exposure because they reflect sunlight toward your face.  

What to Look for When Getting New Sunglasses

When choosing new sunglasses, make sure they’re labeled 100% UV protection or UV400. Although most pairs sold in the United States and Canada offer this degree of protection, it’s still worth confirming before making the purchase. Keep in mind that factors like cost, polarization, lens color, or darkness don’t have much to do with the level of UV protection. Even clear prescription lenses can be UV protective. 

It’s important to note that there is a lot of counterfeit sunwear in the marketplace. This is dangerous since counterfeit eyewear may not provide much-needed ultraviolet protection. So if the price of a renowned brand is too good to be true, it’s probably a fake. 

The size and fit of the sunglasses is important. Bigger is definitely better if you spend a lot of time outdoors. Larger wrap-around eyewear is best if you regularly ski or spend many hours in the water, as this style blocks light from all directions. 

To find out whether it’s still safe to wear your favorite shades, visit a New Hamburg eye doctor to determine whether your lenses still offer the right level of UV protection. It’s also a good opportunity to discuss prescription sunwear.

Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness: 

  • Age-related macular degeneration (AMD)
  • Cataracts
  • Glaucoma
  • Diabetic retinopathy

The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list. 

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusion, thyroid-related eye disease, and stroke-related vision loss. 

The connection between obesity and eye disease is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Our eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair! 

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in dark green leafy and orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases. 

We Can Help Keep Your Eyes Healthy in New Hamburg

While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. Howard Dolman can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.

If you have any questions or concerns regarding your vision or eye health, don’t hesitate to call Dolman Eyecare Centre — we’re here for you. 

How Smoking Impacts Vision

Smoking harms nearly every system in your body — including your eyes. 

Though we are all aware of the health effects associated with smoking, such as lung cancer, heart disease, and tooth decay, few know about the negative impact it can have on our vision. 

Smoking and Eye Disease 

Smoking, especially 20 cigarettes or more daily over a long period of time, can adversely impact your vision. Cigarette smoke is made up of compounds that can damage health and have been shown to cause cerebral lesions which affect the area of the brain that processes vision.

More specifically, tobacco addiction increases the risk of developing vision-robbing diseases such as macular degeneration (AMD), cataracts, glaucoma, diabetic retinopathy. Moreover, smoke is an irritant that can cause or exacerbate dry eye syndrome. Below we’ll delve a little further into each of these conditions. 

Age-Related Macular Degeneration 

Smokers run a high risk of developing AMD, a condition that severely impairs central vision, making it difficult or impossible to read, drive, recognize faces and colours, and leads to permanent vision loss in those aged 65 or older. Fortunately, the risk can be dramatically diminished by putting an end to tobacco smoking — even if later in life. 

Cataracts

Heavy smokers double their risk of developing cataracts, the leading cause of blindness. Cataracts are characterized by cloudy, blurred or double vision, photophobia, and reduced night vision. However, cataract surgery is a common procedure which replaces the clouded lens with an artificial intraocular replacement. 

Uveitis

Uveitis, the inflammation of the eye’s central layer, is an ocular disease that can lead to blindness. This condition damages important structures of the eye, notably the iris and retina, and can lead to cataracts, glaucoma and retinal detachment. Smokers have a 2.2 times higher risk of developing uveitis than non-smokers. 

Diabetic Retinopathy

Smoking raises one’s risk of developing diabetes by up to 40 percent thereby increasing the risk of retinopathy as well. Diabetes damages the blood vessels in the retina, causing them to leak blood into the eye, which — in severe cases — can deprive the retina of oxygen and result in blindness.

Dry Eyes

Dry eye syndrome is a common eye condition characterized by insufficient tears, or when the tears are not composed of the correct balance of water, lipids, and mucous to maintain proper lubrication. Common symptoms include red, itchy, and gritty eyes.

Heavy smokers, and those exposed to secondhand smoke, not only double their risk of developing dry eye but also exacerbate an existing condition, especially among the contact lens wearers.

Secondhand Smoke and Eye Disease 

Secondhand smoke— which includes the smoke that emanates from the end of a cigarette as well as the smoke exhaled— is nearly as harmful to health and vision. Second-hand smoke places others’ eyesight in danger, particularly for young children and infants. Furthermore, studies indicate that women who smoke during pregnancy put the newborn baby at risk of being born with eye disease or visual impairment that could affect his or her ability to learn.

Stop Smoking to Save Your Vision

The good news is that giving up smoking can have an immediate effect on your health — and it’s never too late to quit! Once the habit is broken, your body will begin to repair itself to prevent vision loss. It can be challenging to quit, as it requires dedication, support, and advanced planning. Dr. Howard Dolman and the rest of the staff at Dolman Eyecare Centre in New Hamburg care about your health and will be happy to provide any assistance or resources to help you quit smoking and improve your eye health. Keep in mind that if you smoke, quitting smoking is the most important step you can take to protect your health and vision.
