How does diabetes affect the eye?
Diabetes causes weakening of the small blood vessels in the body including the retina which serves as the screen in the eye. Diabetic retinopathy is gradual in onset and is related to the duration of diabetes. High blood glucose levels, high blood pressure ,smoking and genetics influence the development and progression of diabetic retinopathy.
Eye examination in diabetic retinopathy
Every diabetic is a potential candidate for diabetic retinopathy. There are no symptoms at the initial stages. Periodic eye examination with dilated pupils is the only way to detect early disease and prevent further worsening of vision.
