The retina lines the back two-thirds of the eye and is responsible for receiving visual images. Retinopathy means disease of the retina. There are several types of retinopathy but all involve disease of the small retinal blood vessels. Signs of retinopathy (see photograph) can be seen when the retina is viewed through the pupil with an ophthalmoscope. The August 22/29, 2007, issue of JAMA includes an article about management of diabetic retinopathy. This Patient Page is based on one previously published in the January 5, 2005, issue of JAMA.
