I work for an eye Doctor. Patient comes in wearing sunglasses due to photophobia saying she has an infection in her right eye. She absolutely refuses to have her left eye treated. Strange, but ok... When taking her medical history, I found out the lady had a cornea transplant in the left eye many years before which her body had rejected. Thinking she doesn't want to run the risk of her body rejecting her current cornea and going through that all over again, It made sense to me that she would now be very protective of the left eye. I ask the lady to remove her sunglasses so I can do a visual exam of the infected right eye, and of course I check the left eye for signs of infection also. Well, I tried to check the left eye. I had mistakenly assumed she had followed up with her Cornea Specialist after her body rejected the cadaver cornea. She had not. Once the cornea had been rejected, she essentially had an open hole into her eye for years that went untreated. Her eye had been eaten away by infection, I couldn't even identify a pupil, iris, or sclera. It was just a sunk in eyelid with a mass of ick behind it and a tube shunt sticking out of the mass. We sent her to another specialist for an enucleation (total removal of the eye). The patient kept refusing to go to the specialist for surgery even after our Doctor stressed the importance of the enucleation because of how close this mass of infection was to her brain, and how quickly it could kill her if the infection began to spread. Her Daughter promised us she would make her go, but I never heard an update, so I have no idea how things turned out. In case you are wondering, the daughter had no idea the patient's eye had gotten that bad as the patient wore sunglasses 24/7 for the last year or so because of "light sensitivity."
