Diabetic Retinopathy

Diabetic retinopathy affects

the blood vessels of the retina, the portion of the eye that receives

visual images. High levels of blood sugar cause these blood vessels

to leak fluid into the macula (the light-sensitive part of the retina),

which in turn causes the vision to become blurred. If left untreated,

this can lead to blindness. In advanced stages of the disease, new

blood vessels can grow over the retina, causing scar tissue and,

in severe instances, retinal detachment. This disease only affects

people with diabetes, but in staggering numbers—one out of

every two diabetics will develop diabetic retinopathy.

In its earliest stage, you may not notice any difference

in your vision. Often the first sign are floaters, particles that

pass across your field of vision but are not really there. Difficulty

doing close work or double vision can be signs that blood is leaking

into the macula. This leads to swelling, also known as macular edema,

a condition that usually causes blurry vision.

Diabetic retinopathy is diagnosed by test called

a flourescein angiography, wherein dye is introduced into the body.

The blood carries the dye to the retina, and once there the eyes

are photographed by an ophthalmologist, who can then determine the

seriousness of the condition.

In extreme cases, laser surgery is performed

to close the leaking blood vessels. It can also be used to remove

the “stray” blood vessels that have grown on the retina.

When it comes to diabetic retinopathy, the best plan is a defensive

one. Keep your blood sugar and blood pressure under control, get

regular eye exams, and eat a healthy diet that includes many cruciferous

vegetables, such as cauliflower, broccoli, and cabbage.
