I have pigmentary glaucoma and am slowly going blind. I had started to get large, dark floaters and sparkling blue lights in my eyes and, because I’ve been diabetic most of my life, I went my doctor and told him I suspected glaucoma. He sent me to an eye clinic and they didn’t find anything. My doctor acted like I was hypochondriac so I stopped bringing it up.
Five years later I started suddenly seeing five of everything one night and ended up in the emergency room. Turns out I had pigmentary dispersion syndrome (a very rare form of glaucoma), and I’d had it so long that it had already done significant damage to my optic nerves. The thing is, as long as there’s even a few nerves left, you can have perfect vision. But when the last few are gone, you’re blind. I had experienced so much nerve loss that when the pressure increased in my eye that night, my optic nerves started misfiring.
I take eyedrops to slow the damage, which might save my vision long enough for something else to kill me before I go blind, but I have to be cautious about exercise, high-impact sports, or getting truncheoned in the head by police because my condition is caused by a malformation of the eye which causes pigment from the iris to be scraped off (leaving odd colourless areas in my iris), which forms a slurry and blocks the trabecular meshwork which is supposed to drain fluid from the eye. Any impacts can cause bits of pigment to break off and cause the pressure in my eye to shoot up, killing what few nerves I have left.
