I had eye surgery in October of last year, and have had a fixed, dilated pupil ever since. This is due to increased post-operative pressure that got too high in that eye. When I called the evening after surgery complaining of a tremendous headache, I was told that it was normal and to take Tylenol, and come in early the next day if it was still bothering me. By the next morning, my headache had escalated to a migraine. There was no surgeon there to see me for a post-op visit. The optometrist wasn't able to reduce the pressure with drops. I was driven to Tacoma where the nearest surgeon in this company was, who tried the same series of drops, and when they were again unaffective, he performed a small surgery to release the fluid. I have since been diagnosed with Urrets-Zavalia Syndrome.
