Diabetes can cause various changes in the eye particularly in the retina. Diabetic eye disease can cause severe vision loss or even blindness. When the retina is affected by diabetes, weakened blood vessels may leak fluid or blood, causing damage to the retina. This is called DIABETIC RETINOPATHY.

Please note that every person with diabetes need not have Diabetic Retinopathy. Conversely an eye with marked changes of Diabetic Retinopathy can have good vision and be totally free of symptoms. Hence it is important for all diabetics to undergo REGULAR EYE CHECK-UP INCLUDING RETINAL EXAMINATION THROUGH DILATED PUPILS especially for people who have been diabetic for a number of years. It is also true that diabetes is often detected in a person, when some changes of retinopathy are seen on routine examination of the eye.

Reduced central vision can occur if the macula gets edematous (swollen). Black spots (floaters) and cobwebs of sudden onset often point to a minor bleed inside the eye. Sudden total loss of vision may occur due to a large bleed into the vitreous.
