Below is an OCT of the right eye macula. An OCT takes a cross-sectional view of the retina. The macula is the part of the retina that serves the center of your vision. You can see the dome-shaped space under the retina by the fovea (the exact center of the macula). This dome-shaped space is focal detachment of the retinal pigment epithelium. The patient see's 20/20. Below that is an RPE detachment from another patient. Notice the double dome.

OCT IN GLAUCOMA
Optical Coherence Tomography (OCT) measures the thickness of the nerve fiber layers, which are thinned in glaucoma. The image below shows what glaucoma does to the nerve fiber layer around the optic nerve (top graphs) and the ganglion cell layer around the macula area.
OPTIC DISC DRUSEN
Here's a picture of optic disc drusen lifting up the optic nerve. Notice the globulated look to the optic nerve rim.

GRANULOMA FORMING AROUND A PALPEBRAL CONJUNCTIVAL FOREIGN BODY
This was a very interesting case because the patient had reported getting something in his eyes months before. He resisted coming in and said it felt better as time went on. However he still feels something is under his eyelid, albeit not painful.
Upon examination he had a foreign body that was tucked into a crevice of this granuloma. I took the foreign body out before taking the photo (I was half tempted to tuck it back in when I realized it would have made a good photo...LOL).
So theoretically what happened is the foreign body was smooth enough to keep him from being miserable, but rough enough for the conjunctiva to form a granuloma around it...a natural reaction of the eye to protect itself. I thought it was interesting. I wish I'd gotten that photo with the foreign body included.
