It is important to document the findings of most retinal diseases and conditions, especially diabetic eye disease findings, macular degeneration, epi-retinal membranes, macular holes and retinal tears and detachment.

The patient’s pupil must be well dilated in order to perform fundus photography. Dilating the pupils will cause blurry vision, especially reading vision, for several hours, if not, days – depending on the type and strength of dilating drop used. A diagnostic study called fluorescein angiography (FA) uses fundus photography to capture images of injected dye circulating throughout the retinal blood vessels. This is a very helpful study that can show leaking, swelling or circulation problems caused by various eye diseases like diabetic retinopathy and wet macular degeneration.
