YouTube Video: If You Don’t Have Any Vision Problems…Why Should You See an Eye Doctor?

You don’t have any vision problems….your vision is perfect……so why should you get your eyes examined yearly…or at all??  Do you know anyone who has really good eyesight…and feels that there is no reason to go to the eye doctor because they don’t need eyeglasses??

Well, the above YouTube video is for YOU and THEM!

A common misconception is that the only reason to see an eye doctor is to get some glasses, contacts or to get their prescription updated.  Does this sound familiar??

A comprehensive eye exam is MOSTLY about checking the HEALTH of your eyes.  A lot of eye health problems – diseases and disorders of the eyes (like glaucoma, retinal holes and tears etc) – do NOT cause any kind of symptoms (like blurred vision, headaches, pain, feelings of “pressure” in and around eyes etc…).

Just because you can see clearly, see colors correctly and don’t notice any vision problems does not necessarily mean that your eyes are healthy.

Did you know that a comprehensive eye exam can ALSO provide early detection of some SYSTEMIC problems.  All sorts of systemic problems – like Diabetes, High Blood Pressure, High Cholesterol, Brain Tumors etc….can be detected during a comprehensive eye exam. If your eye doctor suspects that you may have a systemic problem then, he or she can refer you to your primary care doctor for further evaluation and testing to determine if you have the systemic disease.

Diabetic Eye Examination and Diabetic Retinopathy

Informative Video from the Joslin Diabetes Center

Diabetes is the #1 Cause of Preventable Blindness in the U.S. Most of the time there are NO symptoms of diabetic eye problems.  You can have diabetic retinopathy and not even know it.  Many patients can still have fairly good vision even with advanced stages of diabetic eye disease (diabetic retinopathy).   

Diabetic retinopathy is a term used for pathology (bleeding, fluid build up and/or abnormal blood vessel growth) in the nerve lining of the inside of the eye that we use for our vision – called the Retina.

This kind of diabetic pathology is caused when elevated blood glucose (blood sugar) damages the blood vessels in the retina – causing bleeding and fluid build up in and around the retina.  Blood sugar is monitored via blood glucose testing and Glycosylated Hemoglobin (HbA1c) testing (which tells the primary care doctor the average blood glucose in someone’s blood for the past few months – not just the glucose reading on the day of the testing).

Therefore, it is essential for diabetics to have a comprehensive eye examination at least every 12 months – even if their blood sugar is under control. A comprehensive examination should include a dilated eye exam with retinal imaging (digital retinal photography) to document the presence or absence of any diabetic retinopathy.  Retinal photography is essential to pick up and document any subtle diabetic changes in the retina from year to year.

The sooner any diabetic eye problems are diagnosed and treated, the lower the risk of visual loss and/or blindness from diabetic related complications.

So, if you are diabetic or know anyone who is diabetic – a yearly dilated diabetic eye exam is essential for prevention of vision loss from diabetes.
