AKA Holmes-Adie's syndrome. I was diagnosed with Aide's* pupil in 2003. After going for a routine eye test the optician refered me to the hospital for further tests.

Aide's pupil can be the result of nerve damage so I was given a brain scan and told to return in a few weeks when the results were through.

Thankfully the brain scan was clear. When I returned to see the optical eye expert (there must be a proper name for such a person) he had invited a coleague to sit in as we who suffer with this syndrome are apparantly quite rare.
