@richardab, When I noticed odd lights in my vision, I contacted my PCP. He sent me to my Opthamologist who sent me to the Retina specialist who saw me the next day. My diagnosis was BRVO (Branch Retinal Vein Occlusion). I also had injections monthly/6 weeks apart for a while, then they were spaced further apart, then they were weekly, further apart ...as indicated by the retina scans that he used. The good part for me is that eventually my condition stabilized and the blood leakage stopped. I am still checked by my opthamologist and will be sent back to retina specualist when/if there is a change.
As for my vision, I have a blurry spot in the vision of my affected eye. My other eye (says opthamologist) is compensating for the damage.
I am immunosuppressed due to organ transplant, but that has been ruled out as a cause. The retina doctor said that it looks to be a physical factor related to way the veins are arranged in the rear of my eye,
I found it helpful to take a tylenol and to lie down with a cool wash cloth over my eyes when I got home from the appointment. I was not allowed to drive home and had to bring a driver (husband). How did your first injection go for you?
