What is diabetic retinopathy?
Diabetic retinopathy is the main cause of blindness in people younger than 60 years of age. It affects the vessels at the background of the eye (retina), which leak fluid and also bleed. If the macula is compromised (the central sensitive area of the eye), there is drop of vision. Few diabetics also develop abnormal vessels inside the eye (new vessels), which are fragile and can bleed, causing sudden drop of vision. Finally, occassionally normal vessels can be so affected, that blood circulation inside the eye is disrupted and due to cell death, drop of vision is irreversible.
