Hypertrichosis of the upper cheek area associated with travoprost treatment of glaucoma.

Travoprost is a prostaglandin analog used in the treatment of open-angle glaucoma. This drug is safe and efficacious and has a low incidence of systemic and local side effects. Common local side effects are conjunctival hyperemia, iris pigmentation, and hypertrichosis of the eyelashes. The authors present a case of a patient who developed marked hypertrichosis of the cheek vellus 3 months after starting treatment with travoprost.
