Deepening of lid sulcus from topical bimatoprost therapy.

PURPOSE: To report a new adverse effect related to treatment with bimatoprost. CASE REPORTS: Serial clinical examination of three patients was performed. In each of the three reported patients, alteration of eyelid appearance with deepening of the lid sulcus was evident as the result of topical bimatoprost therapy. DISCUSSION: A comprehensive literature search of Medline using WebMd and MDConsult, was conducted to cross reference known side effects of topical prostaglandin analog treatment. The keywords utilized were prostaglandin analogs, prostaglandins, prostamide, glaucoma, ocular hypertension, intraocular pressure, side effects, adverse effects, bimatoprost, latanoprost, lumigan, and xalatan. This appears to be the first such report in the literature. Clinicians and patients should be made aware of this possible complication of topical bimatoprost therapy.
