I have occasionally had that happen, and I know it's difficult to cope with. Constant tearing is a known factor of chronic dry (not dry amd) eyes. I have never heard or read that it is related to macular degeneration, althogh the two can occur together. It is strange to think that dry eyes and tearing go together, but they do. There could be another reason for the tearing, but only your doctor or an optometrist could tell you that. Have you ever felt that your eyes could be dry (when they're not tearing!)?
