DIABETES AND YOUR EYES

Diabetes may affect many areas of the body including our eyes. Diabetes can produce varying degrees of vision loss. In fact, it is one of the leading causes of blindness. Diabetes may affect the vision by causing Cataract, Glaucoma and most importantly Diabetic Retinopathy. Diabetes seriously threatens vision because it may damage the retina. Diabetic Retinopathy is a "Silent Killer of our Vision" with no outward symptoms in its early stages. It’s not until the later stages that vision loss is noticeable. Detected early, it can be monitored and treated most of the time. Left untreated, it may lead to blindness.

HOW DOES DIABETES AFFECT THE RETINA?

Retina is the delicate inner lining of the eye, it is like a film within a camera, that sends visual messages to the brain. It contains tiny blood vessels that provide it with nutrition. Diabetic retinopathy weakens these vessels, causing blood / fluid to leak into the retina. When this happens, the retina swells up and vision is affected. More serious changes, which occur, are, development of abnormal blood vessels, which are fragile. If these abnormal blood vessels burst, blood will fill the back of the eye and prevent light from reaching the retina. The result is loss of vision.Cataract

HOW DO YOU KNOW YOU SUFFER FROM DIABETIC RETINOPATHY?

Seeing Flashes of lights, black spots, floaters (small specks moving in your field of vision) and cobwebs or sudden loss of vision are signs of retinal disease requiring urgent examination.

HOW TO PREVENT BLINDNESS OCURRING DUE TO DIABETIC RETINOPATHY?

Early detection and treatment is the key to prevent loss of vision. Most diabetics will develop some form of diabetic retinopathy. In the early stages, diabetic retinopathy is unnoticeable. You will not experience pain or blurring – or even be aware you have a problem. That’s why; if you are diabetic, constant evaluation is critical and a regular COMPLETE eye examination is recommended. If you have poor control of your blood glucose, high blood pressure or protein in urine, eye examination should be more frequent.

If the doctor suspects leakage there maybe the need of a test called FFA – Fundus Fluorescien Angiography). In this test the doctor injects a dye into the blood and when the dye reaches the eye, the doctor can instantly examine the eye by the digital computer images generated and then decide on whether Laser Treatment is necessary.

Remember….

  • Most diabetics will develop diabetic retinopathy….. usually in both eyes.
  • Diabetic Retinopathy is one of the leading causes of blindness in adults.
  • Laser Treatment can treat diabetic retinopathy and reduce the risk of blindness.
  • Early detection and treatment is the key to preventing blindness.

Warning Signs……

Seeing Flashes of lights, black spots, floaters (small specks moving in your field of vision) and cobwebs or sudden loss of vision are signs of retinal disease requiring urgent examination.
