I am 46 yr old female recently dx with CRVO with no underlying cause approx 2.5 weeks agao, I have no HTN , NO diabetes, all lab work came out negetive, I had shot of avastin go back in 1.5 weeks for follow up with possible second shot, Dr says I present very differently then he has seen before..my question is , I am now having some dizziness/near syncopal episodes, is this normal? also I had a cat scan and it also was negetive.. should the "web" like appearance I have in my vision in that eye go away?
