The vision from my CRVO eye is like looking at a large jigsaw puzzle of a scene - with half of the jigsaw pieces painted light grey. Thus I get no vision data information from these grey areas - but do get information from the other areas. Hence , with only my bad eye open, I can see enough ( information) to get around - but insufficient for any detail. I can walk down a footpath unaided and see people coming towards me - but I cannot see what sex the people are ( man or woman) until they get much closer.
My RS is giving me Lucentis injections and seems to be concentrating on getting my macular edema (swelling) under control - and I understand that this process is the same as he does for people with aged macular degeneration. BUT - my problem is more than just macular edema , that is a secondary effect of the vein blockage and resulting retinal hemorrhages.
I understand that the CRVO cannot be "unblocked" - so what is the point of having injections to correct macular edema if I am left with a damaged retina?? What is causing the visual experience that I have - the hemorrhages, the edema or a combination of both. What would happen if I stopped having the injections??
