“Will My Child Be Nearsighted?”
Following the American Optometric Association’s recommendations of performing eye exams for children before age 1, at age 3, and before starting kindergarten, that is one of the most common questions that Dr. Knighton and I get. Parents who are nearsighted, or myopic, especially ones who got their first glasses in elementary school, often want to know if their child is going to be nearsighted too.
Over the years, optometrists have had many theories about whether a child will be nearsighted or not. Some of these theories have been helpful, and some have not. Now, thanks to some outstanding research published in this month’s issue of the journal JAMA Ophthalmology, we are closer to an answer.
With 1 simple eye examination, we can now more confidently evaluate if a child will be nearsighted in the next few years.
“Why is my eye changing color?” is a question we are asked from some patients. While there are conditions that can change the actual color of the eyes, typically the “color change” they are noticing is an accumulation of cholesterol deposits in the cornea. Yes, cholesterol!
The Center for Disease Control (CDC) estimates that 27.9% of Americans have high cholesterol. Most of the time high cholesterol has no symptoms, so many people may not even know they are affected. More importantly, if people are aware of cholesterol, they seldom think about how it affects their eyes. Neither are they aware that a complete, dilated eye exam can detect signs of high cholesterol.
When Dr. Nate and I evaluate the eyes during an exam, we look for signs of high cholesterol in several places:
Yellow fatty deposits of cholesterol can show up on the eyelids or on the skin around the eyelids, called xanthelasma (zan-the-laz-muh).
With the microscope, we look for cholesterol deposits in the cornea, called arcus. Normally the cornea is a clear tissue on the front of the eye, but when cholesterol deposits develop, it causes a white or gray ring to develop along the outer edge. The cornea is a natural place for cholesterol to accumulate over time, so this is a common finding in patients over 60 years old.
A piece of cholesterol, or plaque, may be seen in the arteries of the retina after dilating your eyes. If there is a small plaque in the retinal vessels of the back of the eye, it is likely that there are larger plaques in other places of the body. Large plaques increase your risk for heart attack and stroke. This is one more reason why we encourage patients to have their eyes dilated at their annual eye exams. With both eyes dilated, Dr. Nate and I can look closely at those vessels to rule-out these kinds of concerns.
If Dr. Nate or I find any of these signs, especially if you are under 60 years of age, we may ask you more questions about your lipid levels or even recommend that you get blood tests done with your primary care doctor.
Don’t delay your annual eye exam! Getting your eyes checked should be included in your routine “appointment days.”
