Diagnostic Tests

Fundus Autofluorescence

This is a special photographic method used in the diagnosis of optic nerve and some retinal diseases. Photographs are taken of the retina and optic nerve with a special device after enlarging the pupils and are used particularly to determine and follow the course of changes in the pigment epithelial layer, which is the base layer of the retina.
