Hypertension could be lurking in your eyes

This past holiday, 26 people from my family gathered to celebrate. At some point in the evening, one of the hosts, who has diabetes and high blood pressure, had his blood pressure cuff sitting around; it’s a digital wrist cuff. You can’t have one of those things sitting at the table around this curious group without someone picking it up and playing with it. It became a game—a betting game, of course. We’re not just curious, we’re also competitive. It was all fun and games and while no one’s eye came out (gross), three of the men at the table showed frighteningly high blood pressure. All are relatively young men, seemingly healthy. And, while we were all participating in the spirits that accompany such a bash, the number of others who “played” our game offered a good enough control group of consistently accurate readings.

There could be several reasons that cuff read so high for these guys…user error, cuff too low in relation to the heart, vessels too far beneath the skin, and so on. However, we tested each person at the table three times, at different intervals and stages of rest. All fluctuated in heart rate, but consistently presented similar blood pressure. These three guys, whom I love and respect, could be ticking time bombs. I found myself in a quandary. I’m concerned. The writing seems to be on the wall, but I’m not a doctor. Should I say something?

I did. I couldn’t just sit back and let this slide. It was difficult to address when it’s not my expertise—not even close. But, I did it, privately and after the celebration. By talking to them, I had nothing to lose. If I didn’t speak up, I could literally lose them. I shared my concern and asked them to take the opportunity to get a way-past-overdue physical, including a COMPLETE eye exam by an optometrist.

They had no idea that a look into the eye may reveal the silent damage wrought by high blood pressure and diabetes and reflect the risk of a future stroke or heart attack. All I can do is hope they share my concern and check it out. If nothing else, they’ll have an answer. If it turns out to be nothing, they’ll have a reason to hassle me (the nosey-Nellie/worrywart). There has to be at least one of us to razz while sitting at the poker table. In this case, I’ll gladly wear that hat. If it turns out we caught something by playing our little impromptu game, then I’ll just be happy to be sitting at the table with them for a while longer.

No matter who you are, regular eye exams are important for seeing more clearly and seeing signs of diseases like hypertension, glaucoma, and diabetes.

New Year Nutrition: What’s your resolution?

We’ve had about two months of food indulgence–with all the sugar-filled, butter-beaten, and flour-ridden baking we could eat. And now that we’re into 2012, many of us nod to a resolution to eat better and get our bodies moving a little more. There’s a lot to be said for a good resolution and actually sticking to it.

But, we could be gluttons (of other things) all year and be better off for it. There’s much research boasting of the health benefits of eating lots of green leafy veggies, brightly colored fruits, and lean fresh proteins. All of these not only help us stay lean, they also help our eye health.

Just like the rest of our body, our eyes need certain vitamins and nutrients to stay healthy. Keeping it all straight isn’t easy—we’re bombarded with supplements and short cuts all the time. If we absorbed all the nutrients we need for good eye health by eating them rather than taking supplements, there’d be no room in our stomach for all the junk food surrounding us everyday.

Here are some eye healthy vitamins and where to find them in our food.

Vitamin A and zinc

Vitamin A helps prevent night blindness, and helps us to maintain a healthy, clear cornea. On the other hand, a deficiency of vitamin A can lead to glaucoma, dry eye, and other degeneration.

Vitamin A – Found in Orange Fruits and Veggies Zinc
  • Carrots
  • Sweet Potatoes
  • Pumpkins
  • Mangoes
  • Apricots

These all contain Beta-carotene. Our body converts Beta-carotene to vitamin A.

  • Oysters
  • Hamburgers
  • Wheat
  • Nuts and Seeds

Zinc helps the body absorb vitamin A, and also helps prevent against macular degeneration and night blindness.

Lutein and zeaxanthin

Lutein and zeaxanthin are carotenoids that function as an antioxidents in the lens and retina. They increase pigment density in the macula, and filter out high-energy blue light. This helps protect your retina, and lowers your risk of macular degeneration.

Lutein and Zeaxanthin
  • Carrots
  • Spinach
  • Kale
  • Swiss chard
  • Other leafy greens

Vitamin C and bioflavonoid

Given the wide variety of benefits of vitamin C, hopefully it has already cemented a place in your diet. That said, with regard to eyesight, vitamin C has been linked to the prevention of cataracts and the delay of macular degeneration. It can also help prevent and alleviate glaucoma.

Vitamin C  This list could go on and on—think brightly colored, fresh fruits and veggies
  • Oranges
  • Strawberries
  • Broccoli
  • Red Peppers
  • Peaches

Sometimes called vitamin P (though they’re not vitamins), bioflavonoid work as antioxidants and help your body to absorb vitamin C. Bilberry is an often-named source of bioflavonoid, but it can be difficult to find. Most foods that contain vitamin C also contain bioflavonoid, however, so you’re covered pretty well.

Vitamin E and selenium

Studies have shown vitamin E may help prevent cataracts, as well as contribute to preventing macular degeneration. Selenium helps the body absorb vitamin E, as well as to produce its own antioxidants.

Vitamin E Selenuim
  • Spinach
  • Nuts
  • Kiwi, Papaya, and other Tropical fruits
  • Red Peppers
  • Broccoli
  • Unprocessed Wheat
  • Oils
  • Brazil nuts
  • Sunflower Seeds
  • Chicken and Turkey
  • Mushrooms (button, crimini, shiitake)
  • Onions
  • Grains
  • Fish and Seafood

Fatty acids

Fatty acids are important for visual development in infants. In adults, deficiencies can lead to impaired vision, and increase risk of damage to the retina.

Fatty Acids: Omega-3
  • Cold-water fish
  • Salmon
  • Mackerel
  • Trout

National Handwashing Awareness Week: December 4-10

It’s funny when you think about it–we have a week set aside to remind us to wash our hands. But, it’s a good thing we do, and it’s just in time for the holidays. Things commonly found on the everyday doorknob, escalator handrail, or light switches are pretty grotesque. One touch to our eyes and before we know it, we’re infected with a whole host of things trying to

take us down. Our eyes are more than just vehicles for sight; they are a gateway for infections, too.

The power is in our own hands (literally) to prevent many illnesses. Imagine how great it would be if you or your family were never sick again from a respiratory infection, especially during what may be a hectic holiday season. By washing our hands regularly and properly, we can prevent illnesses such as the Flu, the common cold, pink eye, sore throat, bronchitis, pneumonia, strep throat, tuberculosis, and many more.

Below are some basic principles from the Mayo Clinic for hand awareness.

Always wash your hands before:

  • Preparing food or eating
  • Treating wounds, giving medicine, or caring for a sick or injured person
  • Inserting or removing contact lenses

Always wash your hands after:

  • Preparing food, especially raw meat or poultry
  • Using the toilet or changing a diaper
  • Touching an animal or animal toys, leashes, or waste
  • Blowing your nose, coughing or sneezing into your hands
  • Treating wounds or caring for a sick or injured person
  • Handling garbage, household or garden chemicals, or anything that could be contaminated—such as a cleaning cloth or soiled shoes

Above all, DO NOT put your fingers into your eyes, nose, or mouth.

The polls are in!

Over the past few months, we’ve posted several polls on the VSP Facebook page that have garnered some great results! The polls have helped us learn more about our wonderful VSP members in a fun and engaging way.

In a recent poll VSP members were asked how long it had been since the last time their children had an eye exam. As it turns out, 75% of respondents have taken their children to see a VSP doctor in the past year! And, we would love to see the other 25% of respondents start taking their children in for annual eye exams as well, since more than 60% of children with learning problems have undiagnosed vision problems. And, getting your child an annual eye exam can help them learn, succeed in school, and experience life’s moments clearly. Discover how you can ensure your family gets the eyecare they deserve here.

Another poll asked VSP members when they started wearing glasses. 51% of poll takers started wearing glasses between the ages of 0-15 years old! With so many individuals reaping the benefits of glasses it makes sense that we share the hundreds of stylish eyewear options available for you and your family here. 

The results of a third poll helped us see that members realize the importance of annual eye exams. We asked members when their last comprehensive eye exam was, and 74% of respondents have received one in the past year! Annual eye exams can reveal signs of eye-related and other health conditions, like:

  • Diabetic Eye Disease
  • Macular Degeneration
  • Glaucoma
  • Diabetes
  • High Blood Pressure
  • High Cholesterol
  • Multiple Sclerosis
  • Risk of stroke
  • Risk of heart disease

Eye Exams ─ A Proactive Way to Monitor Your Health

At VSP Vision Care, we like the idea of preventative medicine a lot more than we like the idea of regular medicine. That’s because when it comes to health, we’d rather be proactive than reactive. For example, fixing a broken leg is good, but not breaking a leg in the first place is even better.

Being proactive means putting in a little effort now to save time, money, and the stress of dealing with a serious health problem in the future. Ultimately, it could even save your life.

One of the easiest ways to be proactive about your health is to get an eye exam every year. In one short office visit, your  VSP eye doctor can check for several common health conditions, including diabetes, high blood pressure, and high cholesterol. Identifying and treating these conditions early is imperative to managing them with as little interruption to your life as possible.

We regularly receive great stories from VSP members who have realized how important annual eye exams are and wanted to share the following ones with you:

“My VSP eye doctor took longer than usual examining my eyes. My eye doctor informed me that I had a gray ring around my cornea, which is a sign of high blood pressure, and referred me to see my primary care physician. My PCP confirmed the diagnosis and provided treatment. I’m truly convinced that you can find health problems through an eye exam.”

- Nancy L.

“My daughter went in for her yearly eye exam and the VSP eye doctor found a retinal hemorrhage. The VSP doctor referred her to see her family physician. She saw our doctor the next day and the doctor could not get a blood pressure reading and she had extremely high urine levels. They sent her to the hospital immediately, where we found out she was in kidney failure and had to go on dialysis immediately. Four months later, she had to get a kidney transplant. We thank God for the VSP doctors who found the hemorrhage! “

- Sharon W.

“After suffering some headaches and nausea, I went to my eye doctor, thinking I needed an updated eyeglass prescription. After a series of tests, the eye doctor concluded that I had “hyperopia”, and that I ran a risk for “narrow-angle glaucoma”. She referred me to an eye surgeon because the intraocular pressure needed to be reduced as soon as possible. I feel very lucky — sometimes you might think the series of tests is excessive or unnecessary, but I feel now that they are exactly what saved my eyesight. Thanks for supporting my eyecare needs, VSP!”

- Joan P.

An annual visit to a VSP eye doctor can play a big role in the early detection of eye and health-related conditions. Check out SeeMuchMore.com for information on the importance of eye exams and to read additional member testimonials.

VSP making strides with diabetes education

VSP was recently invited by the Centers for Disease Control and Prevention to present at an event celebrating the success of the National Diabetes Education Program (NDEP). NDEP is the government’s leading public education program for diabetes prevention and control that offers evidence-based, culturally tailored and easy-to-read materials. VSP was invited to present on our partnership with NDEP to produce educational materials and to serve as a role model to other organizations. We shared the actions we have taken to raise awareness around the link between diabetes awareness and healthy vision, including:

  • Spreading the importance of eye exams for the early detection of diabetes
  • Offering continuing education courses to eyecare professionals about diabetes care
  • Reaching out to optometry students to educate them about their role in health care
  • Providing tools to eyecare professionals to educate patients about diabetes and their eyes
  • VSP’s reach through membership and charity work including Mobile Clinics and Sight for Students

What to expect during an annual eye exam.

A VSP patient receives a comprehensive eye exam from a VSP Optometrist

Ever wonder what all those tests are for during your annual eye exam? Well, your eyes say a lot about you, including providing a look into your eye health as well as your overall health. Your VSP eye doctor performs several tests during your eye exam to ensure your vision is clear, your eyes are healthy, and to check for signs of health conditions.

Check out what your VSP eye doctor is doing during your exam, it’s amazing what your eyes can reveal!

  • Provide your medical and eye history. This will help your eye doctor evaluate your risk for vision problems, eye diseases, and other medical conditions.
  • What’s a Snellen Chart? It’s the chart with the rows of letters; this tests how well you can see far away.
  • Which is clearer? One or two?  When your doctor places a series of lenses in front of your eyes and asks which lens helps you see more clearly, your answers will help your doctor fine-tune your prescription
  • Cover the left, then the right. This test shows how well your eyes work together.
  • Expect a little puff of air. A common test for glaucoma.
  • Get the inside scoop. Dilating drops enlarge your pupils, allowing your eye doctor to see inside your eyes to detect signs of eye conditions and health conditions, including diabetes, high blood pressure, and high cholesterol.
  • See the big picture. Your doctor gets a magnified view of the front and inside of your eyes using a slit lamp or biomicroscope. This helps detect signs of eye conditions, including cataracts, macular degeneration, and diabetic retinopathy.

A more affordable option is now available to treat Macular Degeneration.

Example of effects of Macular DegenerationThe every-increasing cost of healthcare is a concern for many Americans, but even more so for the elderly.

Many suffering from wet macular degeneration, an age-related condition, are treated with a once-monthly shot of Lucentis—costing upwards of $2000 per shot!  So, it’s great news that an alternate drug, Avastin, has been proved an effective treatment for this condition, with costs as low as $50 monthly. Avastin has been used to treat certain types of cancer, and was not originally intended for ocular use.

Consider the potential savings of swapping the drugs, shared in the Philadelphia Inquirer: “Over the course of a year in the study, Avastin cost to $385 from $595, depending on the treatment regimen. Lucentis cost $13,800 from $23,400.”

And the audience for this is huge. The Associated Press quotes Dr. Paul Sieving, director of the National Eye Institute, the federal agency that paid for the study: “More than 250,000 Americans are treated for macular degeneration each year… About 1.6 million Americans have advanced macular degeneration and another 7 million are at risk of developing it.”

While testing still needs to be done before Avastin is officially approved to treat wet macular degeneration, this is a huge development for those struggling with the cost of care.

About Amblyopia (Lazy Eye)

Joel Kestenbaum O.D. is a VSP provider in Long Island, NY.

Joel Kestenbaum O.D. is a VSP provider in Long Island, NY.

Guest blogger Dr. Joel Kestenbaum returns with a post about amblyopia, a.k.a. lazy eye and the importance of early detection.

Lazy eye or amblyopia is reduced vision resulting from vision deprivation to one eye. Reasons include large differences in vision between the two eyes or misalignment of the two eyes resulting in one eye being stronger than the other.

If not corrected at an early age, the lesser-seeing eye may have permanent vision loss.   The brain will usually start to suppress the image of the poorer eye possibly resulting in useless vision.

As an aside, statistics show that 80% of a child’s learning comes through the eyes.  Early detection and early correction are imperative to a child’s binocular eyesight.  I see many young patients whose parents never realized that having an eye exam before age five can affect the child’s lifetime education.  And what is even worse, most pediatricians think that reading the eye chart in their office is an eye exam.  What they also don’t realize is that 20/20 does not mean 20/perfect.  As a result, the doctor’s that see the most children inadvertently do an injustice to their young patients.

Here is one example: Many kids can see 20/20 but if they are “farsighted” or hyperopic, their eyes work hard to focus on distance objects and work harder to focus on close objects.  It’s like the automatic zoom lens on a camera.  When the eyes point to an object, it is natural for the brain to signal the eyes to focus.  The problem is that a child’s eyes have a large amount of focusing power.  The other problem is that the harder a farsighted child has to focus, the more likely that the child will develop a crossed eye, possibly resulting in a lazy eye.

So what do we do about it?  First of all we need to educate the educators and the primary medical providers to screen children and to understand that an eye doctor should examine eyes just as a dentist should examine the mouth.  We need to catch lazy eye early.  Treatment for lazy eye includes eyeglasses, patching therapy, eye drops, surgery, and/or eye exercises.  If not treated, the amblyopic eye may never achieve good vision and may in fact develop functional blindness.

So the bottom line is early detection, early intervention and education.  See you in the next blog.
