I am a senior (70 s) and suffer from double vision in my left eye (since Mar/16). It started after having an upper respiratory infection. the muscle in the lt. eye did not move in sync with the rt. eye. Had c-scan done-- neg. I ve had 2 prior double vision episodes--yr. 2000--rt. eye, yr 2009--lt. eye and now, rt eye again. Can t come toa single diagnosis. The problem resolved itself for the first and second episodes but now have residual double vision corrected by prisms in my glasses. but feels like seeing through a fish bowl. Can you give me some ideas please and thank you
