Ophthalmic Diagnostic Photography
Ocular Fundus Photography
The Fundus, or inner lining, of the eye is photographed with specially
designed cameras through the dilated pupil of the patient. Using Ektachrome
color slide film, the painless procedure produces a sharp view of the
retina, the retinal vasculature, and the optic nerve head (optic disc)
from which the retinal vessels enter the eye. The optic disc measures
about 1.5mm in diameter.

The vessels form an arc around the macula which produces the
central 20 degrees of vision. At the center of the macula lies the tiny
fovea, measuring only 500 microns across, which is responsible
for our most central reading vision. Color Fundus Photogaphy is used
to record the condition of these structures in order to document the
presence of disorders and monitor their change over time. The Diagnostic
Photography Unit produces about 5,000 fundus photographs per month.
