I was in my car following my husband on the interstate when I saw two images of his car side by side in two separate lanes in front of me. They looked identical and I could not tell which one was real. I quickly thought to close one eye and immediately there was only one car. It was obvious that I could no longer drive until this problem was corrected. In my office visits with Dr. Ho I appreciated her expanded education that included the relationship between the brain and the functioning of the eyes. Additional tests ruled out some possible causes, including the electrical nerve impulses from the eye center in the brain to the optic nerve in the eye. I loved that she showed my husband how my left eye which should move in the same pattern as my right eye, did not. When she told me it was probably a condition from birth, I thought there may not be a way to correct it, but there is! A prism was put in my glasses and the result was incredibly amazing. I see only one of everything! I continue specific exercises to help my eyes focus together. A procedure to clean my eyelids close to the tear ducts cleared up some cloudy vision too. All in all, a wonderful experience.
