I'm basically cleared from stroke risk at this point, but it appears that my underlying autoimmune condition (that I don't discuss much but I've had since I was a child) actually tried to attack my retina. Also, the blind spot now occupies about a fifth of my vision on the left side (the area that was previously a blur), and gets pretty close to the center of my vision, which makes reading (or small wire work) harder with my right eye shut.
This is obviously not materially improved, because the blindspot is just as unlikely to diminish (though possible), but I'm now on a different drug that seems to have it under control, and the occlusion is limited to that area. The target drug I'll be on was one that changed my life over a decade ago, and I'm experienced with it, so I'm not too worried, but I've gone through an enormous array of testing and it's been quite a ride.
I do think this is still a delayed outcome from the accident, because my autoimmune disorder had noticeably started flaring up around my eyes after the accident.
I'm still technically and legally okay to ride, but am waiting to clear my initial drug course before trying to do so, since it leaves me pretty shaky and susceptible to infection. I'm at least working in the garage on bike modifications which will hopefully show some nice results soon.
