WHAT IS DIABETIC RETINOPATHY?
Diabetic retinopathy is primarily a disorder of the retinal blood vessels. The retina is the light sensitive membrane in your eye that enables vision. Damage to the retinal blood vessels can cause vision loss or even blindness.
In diabetes the blood sugar levels are too high. This causes the cells that line the blood vessels to swell and become damaged. As a result, the blood vessels may leak fluid or bleed into the retina and this can cause a significant vision loss. As the blood vessels become increasingly damaged with poor blood sugar control, they can become completely obstructed, depleting the retina of blood and nutrients. Abnormal new blood vessels may then grow, and possibly bleed into the cavity of the eye, causing a more severe vision loss.
