Anisocoria. Unequal Pupil Sizes - So What?

ANISOCORIA (An - eye - so - cor - ee - ah)

 Anisocoria, literally Greek for unequal pupils, describes a condition where the pupils of each eye are different in sizes. Approximately 25% of the population may have a noticeable degree of pupil inequality known as physiologic anisocoria. This pupil-size disparity may fluctuate in degree, be found to alternate between sides, and may disappear at times.


In rare cases, a disparity in pupils may be an indication of neurological disease.   

If a difference of pupil size has recently occurred or if you are concerned in any way, call us right away to book an eye examination with one of the doctors.
