Hypertrichosis of the Eyelashes Caused by Bimatoprost

The document reports a case of hypertrichosis (excessive hair growth) of the eyelashes caused by bimatoprost (Lumigan; Allergan, Inc.), which is a new intraocular pressure (IOP)-lowering drug similar to latanoprost (Xalatan; Pfizer, Inc.). Latanoprost, known for its ability to lower IOP in patients with glaucoma and ocular hypertension, has also been observed to stimulate eyelash growth and has been suggested as a treatment for alopecia areata of the eyelashes. The case presented suggests that bimatoprost may have a similar effect on eyelash growth as latanoprost.
