Fundus Photography - Optic Disc


This is just me messing around during free time at work. This is a triple composite. First, the background is a composite of all of the disc photos I have shot since working at the WFUBMC Eye Center. Then I put a fundus image of an optic disc with papilledema in front of that and masked some areas.

This is actually super corny, and I am usually against stuff like this. But whatever.

All shot on ZEISS Fundus Camera

Cataract Composite


This image is a composite of 4 images taken on the slit-lamp camera. Each separate image is called a red-reflex image, because you are lighting the posterior of the eye, and focusing on the anterior lens, so the cataract can be viewed somewhat like a silhouette. So two of the photos were at the nearest plane of sharp focus, while the other two were at the farthest plane of sharp focus. I used Photoshop to mask them together to show the full depth of the cataract.

Definition of Cataract: Opacity or cloudiness on the crystalline lens, which may prevent a clear image from forming on the retina.

Slit lamp: Nikon D100's
ISO: 200
F/22 w/ constant flash
