He also did a schrimers test and I scored only 3 and 4. He prescribed
restasis and I had improvement. But all through this I have also had another strange thing, when I wake up at night in the dark, I see a quick flash of a "C"'. It is a lighted shape, and flashes a couple of times then goes away. I see it everytime I wake up in the dark. I do not notice it during the day, although I have a lot of floaters during the day. Is this a Weiss ring? And is it dangerous?
