Conditions We Treat: Uneven Pupils

The pupil is the black circle in the center of your eye. Unequally-sized pupils (also known as anisocoria) may be noticed by someone who is looking at you, or you may notice the different sizes when looking in the mirror. Anisocoria can be a normal finding in some people (physiologic anisocoria), or it can be a sign of neurologic condition. 

Uneven Pupils: Why Choose Johns Hopkins

Uneven Pupils: Treatments

Treatment for uneven pupils depends on the cause. For patients whose pupils are different sizes due to a normal, inborn variation, treatment may not be needed.
