Abstract

The differential diagnosis for anisocoria is broad and ranges from benign to life-threatening causes. Often, patients with new onset anisocoria present to their primary care physician, an urgent care center, or an emergency room. As such, it is important for non-ophthalmologist physicians to be familiar with its common causes. We present two cases of pharmacologic anisocoria from <i>Qbrexza</i> (glycopyronnium), a wipe used in the treatment of hyperhidrosis. Identifying this medication as a cause of anisocoria in patients with hyperhidrosis can reduce costs and unnecessary testing. Furthermore, physician education about safer usage can be provided.
