In general, there are two major causes of retinal damage due to diabetes, both of which lead to deterioration of vision. The first possible cause is the formation of new and abnormal blood vessels. These vessels can cause bleeding, scar formation, or detachment of the retina from the back of the eye. The second possible cause is leaking fluid from the blood vessels. These events are all painless, so most patients do not realize that they have a problem until it is in its end stages.
Early detection is very important in protecting diabetic patients from vision loss.
Unless otherwise instructed, every diabetic patient should be evaluated at least once a year by an ophthalmologist. Careful follow up can lead to early detection and early treatment, before the patient's sight is affected.
