It started 3 yrs ago. My right eye was dilated & protruding. Eye Dr. asked several times about head trama, no trama. Did all the test MRI. Cat scan, ect...nuthing, no answers. It is still doing the same thing but now the blood vessels are getting smaller in my eye. Family Dr. has put me on meds for high cholesterol, but doesnt thing one has anything to do with the dilating & protruding. I have other symptoms but not sure if they apply to this. I just want some answers.
