Unequal pupil sizes: If there is a difference between the sizes of your pupils, you have anisocoria. If no medical condition or disease can be found to account for it, it is termed "physiologic".

What are some cosmetic approaches to benign anisocoria?

None: Benign anisocoria is usually very subtle and tough for observers to spot. Anisocoria, or different sized pupils, can be from a number of neurological and ocular problems.

MRI/A for head pain/anisocoria read by neuroradiologist said patent PCOAs could not be defined on either side. Could there be an aneurysm in this area then that wasn't seen? Or could I not have PCOAs?

I've had pretty noticeable anisocoria. My MRI was clean and neurologist says my pupils are round and responsive. Could this be caused by taking SSRIs?

I don't think SSRIs would cause this. ...Read more
