I have suffered from migrains for years and have had some occular migrains that cause a blind spot on one side ( for instance when they occure I can only see part of the t.v. etc.) I had a bad fall in Dec.o3 and hit between my eyes on the edge of a metal file cabinet. Since the fall I have had problems with my eyes at times like I am looking through a piece of paper that has black spots on it. Do you know what might cause this. thanks, Marti
