SUSPICIOUS NEVUS

This is what we call a suspicous nevus. It is a dark spot on the back of the eye, like a mole. It has some elevation and needs to be watched very closely for growth. I sent this one to a retina specialist for an opinion. This is the good eye of an 87 year old patient.


CORTICAL CATARACT

A cortical cataract is one that starts on the edge of the lens of the eye and works its way in. The first one shows very small cortical changes. The second one is the same patient in the other eye, showing a little more extension of the cataract. The third one is a different patient with a more classic look. Both of these patients see 20/20 with their correction.







DRY EYE SIGNS

Here's a really good picture of a patient with dry eyes. Fluorescein dye was placed in the eye and a red-free light was shined on the eye to make the tears glow. You can see that within a few seconds the tears break up on the surface of the eye. You can also see damaged surface cells inferiorly.


DRY EYE DAMAGE

The big glowing area is actually fluorescence that indicates damaged surface cells on the eye. This occurs in moderate to severe dry eye. This patient has irritated eyes, especially towards the end of the day. Treatment has to be quite aggressive with this patient. It often takes more than just store bought artificial tears.


RETENTION CYST

While this may look scary, it is really not harmful. These are little pockets of fluid. They can be drained if they are bothersome to the patient.


CLOUDY CORNEAL TRANSPLANT

This is an eye of a patient who had a corneal transplant a long time ago. Most corneal transplants turn out pretty well. This one happens to be somewhat cloudy, likely from low-grade inflammation following the surgery.
