retinal bleed

Has anyone experienced a retinal bleed and lost almost all vision in that eye? The technical term for what I have experienced is called myopic macular degeneration. I have been told that it is caused from being nearsighted not from age. The treatment for this, at least as of last year, was a shot/needle directly into the eye. My eye doctor did not want to put me to sleep for this or give me something to relax me. I had Lasix in the past and wonder if this is related in any way. If anyone out there has experienced this, has your sight gotten any better without any treatment? I only had one of the shots and could not go through that again. It was uncomfortable.
