I had a retina detachment in early March 2014. I had emergency surgery. The ophthalmologist/surgeon noted that I had a secondary cataract and I would need a YAG Capsulotomy after I healed from the Schleral Buckle. All went well and after four month the gas bubble was nearly gone and I scheduled the YAG Cap. About a week before the YAG Cap I experienced a total white-out in that same eye. I happened while I was sitting down and looking down. It cleared immediately when I looked up and came back immediately when I looked down. I thought it was the secondary cataract and it would be corrected by the YAG Cap. It didn't. I now experience the total white-out often (not always) but only when looking down, whether standing or sitting. It clears immediately upon looking straight ahead. This has been going on for two months. I have seen the Ophthalmologist who did the YAG Cap and the retinal Ophthalmologist who is looking after my retina (different from the surgeon). Neither are offering any explanation or advice for what to do now. Is this just a fact of life after the retina detachment. Another weird thing that happens in that eye is what I have experienced before when I have a migraine headache. It will start with a visual blindspot that develops it that eye. It starts as a very small array of thin lines (like a "y"). Over the course of a few minutes, with my eyes closed, the thin lines begin to 'blossom' into a large blob in the general form of a "y". It lasts about 5 minutes (migraine auras always last about 20 minutes). The blob becomes extremely bright (with eyes closed) before fading and disappearing. I had two of these yesterday. Are there any suggestions on what is causing these two things?
