Hi Cinderfella. I'm pretty much going through similar stuff with you. I can't imagine how you work on top of it. You must be Superwoman!! I "work" at home, gardening, putting up food, and caring for the house and livestock, but no harder than I feel up to on any given day. So lucky that way. I wish you were too. Your life sounds truly difficult.
Monday I had Avastin and some laser in my right macula to stop bleeding/inflammation there. Vitrectomies in both, no peripheral left in my left eye (PRP), about half of peripheral left in my right, but my right macular retina won't stop bleeding so I keep needing more laser (the gentler kind for macula) and Avastin shots. I hear you about bumping into things and people that seem to pop out of nowhere. I've developed this owl-like head/shoulder turning when I drive - hyper driver's ed-type checking for lane changes, stop lights/signs, and merging.... I live rurally, so if I lose driving I will become totally dependent on my husband for EVERYTHING. Ugh.
My bleeds are not as dramatic as yours sound, though I did have a couple like that in my left eye a few years ago, before all the work. Left is stable for now.
Anyway, I am sorry your retinopathy is so relentless. I get really down too. It just breaks a person's heart and spirit, and no one really understands. You can look forward to the cataract surgery, though - it's miraculous, I thought. I've had both eyes done, followed by yag surgery and you won't believe how bright colors look afterwards! Magical.
