Has anyone studied the use of marijuana for people who have had CSR? I had it 2 years ago, which lasted for about 2 months. It hasn't fully resolved, as I see a permanant 6 shape when I blink. When I am stressed, and especially if I have been in the heat too much, it gets bad enough that my vision in that eye is affected much moreso and when I blink, I get a negative version of the ghost 6 (ie: it looks like a white flash, with the scar or whatever showing up really abruptly).
