A 53 y/o white male presented with complaints that the vision in his right eye had dropped rapidly over the past week. His left eye was fine... no complaints.

Best corrected vision in the right eye was 20/100, left eye was 20/25.

Anterior segment looked good. There was no corneal problem, nor any anterior chamber reaction.

Muscle fields were normal. IOP was normal as well, 16 in the right, 19 in the left.

Take a look at the photo and you can see what his right optic nerve looked like. The left was completely normal in appearance.

What is this condition? Make sure to go through the hints before you make up your mind.

Don't hesistate to bring this case up for discussion... either on our Internet mailing list or our ocular disease forum. See the URL at the bottom of this screen, or contact me, Walt Mayo, OD, at waltmayo@sccoast.net.

Thanks!
