Is This Retinal Detachment!?

Even though its frustrating that they aren't finding the problem, it is a relief to find out it isn't retinal detachment. I think you are on the right track seeing a neuro- opthamologist. There are some possibilities involving optic nerve function or migraines. Some people get optic migraines that produce strange visual effects, without getting the traditional migraine headache along with it. There is also the possibility of it being "flashers" which are normal. We start out with a gel in our eye which eventually turns more watery. Bits of it can stay in a gel form and can catch the light and make a little flash, and also make shadows on your retina (floaters). I have floaters, and they look like little pieces of lint or when you look at cells under a microscope. Best of luck! I hope you get some answers.
