Is Anisocoria serious?
Anisocoria may not have an underlying cause. Physiological anisocoria is when there is a natural, small difference in the size of a person’s pupils. This is not harmful and does not require treatment. However, a sudden and pronounced change in one pupil size can indicate a medical condition.
What medications cause Anisocoria?
Some Common Causes of Anisocoria
| Cause | Suggestive Findings |
|---|---|
| Drugs (eg, scopolamine patch; cocaine, pilocarpine, animal flea collars or sprays, organophosphates, or aerosolized ipratropium if they contact the eye; cycloplegic, mydriatic, clonidine, or apraclonidine eye drops) | History of use or exposure |
