About Diabetic Retinopathy


The retina senses light coming into your eye, and it sends messages to your brain about the things you see. Damage to blood vessels inside the retina from blood sugar buildup is called diabetic retinopathy. You might not notice changes at first, but over time the walls of your blood vessels may leak fluid. When you’ve had diabetes for a while, blood vessels can form scar tissue and pull the retina away from the back of your eye. This can lead to severe vision loss and even blindness.

What we do

We at Smart Vision do all diagnostic tests relating to retina like FFA, OCT and Fundus photograph. If needed treatment options like panretinal photocoagulation, intravitreal injections are undertaken.
