PIGMENTARY DISPERSION

This photo is of what we call "Kruckenburg's Spindle". It's the pigment cells on the back surface of the cornea. It occurs because zonules from the lens of the eye (behind the iris), rub up against the back surface of the iris, and slough off the dark pigment cells, which then float to the front of the eye and attach to the cornea. The cells also go in the "angle" of the eye where fluid drains. If the drain becomes too clogged up, it can cause pressure to rise, increasing the risk for glaucoma (damage to the optic never because of that pressure).

MACULA ON RETINAL DETACHMENT

This is a picture of a retinal detachment. You can see the optic nerve in the center of the photo, but it's hazy for two reasons. First I focused the camera more forward on the detached retina (above), and there's blood in the eye. The detachment is the billowing, whitish membrane you see above. Normally the retina is attached to the back of the eye. There is no vision wherever the retina detaches off the back of the eye. This patient has a "macula-on" detachment which means, if we get this repaired soon enough, he should have most, if not all his central vision restored.
