I am a 58 year old female who had cataract surgery on both eyes four years ago. The right eye had to have a hole in the retina corrected with laser before the surgery, and the left eye had to have laser treatment a couple years after the surgery to remove a film as a result of the surgery. The current problem I am now experiencing is rather hard to explain, and it has only happened a couple of times. In the outside corner of my right eye I sometimes see a moving colorful liquid, looking sort of like a drop of oil in water. No matter what direction I look, the moving liquid is still there, and it can happen at any time of day or night. There is no pain involved, and it stops within a few minutes. It has never happened in my left eye. I have not yet seen my eye doctor about this problem. By the way, I have MS and do suffer with periodic blurry vision and double vision which is prevented by a prism in my current glasses. Any ideas what this could be?
