This thin film is connected to the back of eye, where it transforms information into electrical signals for the brain to process. The retinae were then studied by light and electron microscopy at detachment intervals ranging from 1/2 hr.

The grey retina can be seen draped over the optic disc, while the tapetum above is. Retinal detachment affects, approximately, one in 10,000 people every year. To diagnose retinal detachment the veterinarian looks into the eye with an ophthalmoscope and takes into consideration observed signs of blindness, diminished vision, and/or a dilated iris.
