How Is Diabetic Retinopathy Diagnosed?

A comprehensive eye examination is the best protection against the progression of diabetic retinopathy. The disease can be detected by viewing the retina with instruments which illuminate and magnify the structures of the eye. If diabetic retinopathy is found, fluorescein angiography is performed to determine the extent of blood vessel leakage. In this procedure, a series of photographs are taken as a dye travels through the retinal vessels. In some cases, ultrasound equipment may be used to check for retinal detachment.
