I've got GA in both eyes now as well. For those unfamiliar, I've gone from being able to see 3 letters in a 5-letter line on an eye chart to being able to see only 2. So if the line says A B C D E, I used to see A C E; now I see A D or A E right next to each other. GA also causes sparkly distortion in and around my central vision. Really trippy! 😛
My ophthalmologist is an M.D. as well as a Ph.D. AMD researcher, so I figure he's got the latest info. At my last visit, on 12/6/22, he mentioned injections for GA that are in the experimental stage and told me to come back in 6 months so there's time for the study results to be compiled and reviewed. He suggested I Google "geographic atrophy macular degeneration therapy" for more info, so I'm starting there.
