When I look in the mirror, I can occasionally see that one of my pupils is more dilated than the other. Sometimes it is the left eye, and sometimes it is the right. When this happens, both pupils are reactive to light. The uneven pupil lasts anywhere from a few minutes to 30 minutes, then goes back to normal. I do suffer from migraines, and have on a few occasions experienced occular migraines. I also suffer from tmj, and the muscles in my left cheek are all messed up. (tight, spasms, ect.) The muscles around my left eye are very tight. I also had an onset of floaters around 8 monthes ago, when my tmj became active. I'm under a huge amount of stress, and don't know if all of these symptoms are contributed to that. Also, I just started to notice my uneven pupils around 8 monthes ago, when I became more 'conscience' of other sysmptoms.What could be causing the uneven pupil? Thanks for any response.
