Anisocoria
From Wikipedia, the free encyclopedia
Anisocoria is a condition characterized by an unequal size of the pupils.
To a certain extent, this is normal. Anisocoria to a mild degree (generally 0.3 to 0.5 mm) can be found in about 20% of people. This form is termed "simple anisocoria." However, anisocoria can be an indication of an underlying syndrome. Several pathologic states may alter the size of the pupil, for example, Horner syndrome or a lesion of the oculomotor nerve. It can also be caused by the application of a transdermal scopolamine patch; it is usually more obvious on the side with the patch and will go away within 3 days .
