To report, with supporting photo-documentation, cases of latanoprost-induced prostaglandin-associated periorbitopathy (PAP).
Retrospective small case series with three cases. Chart review with photo-documentation of clinical features of prostaglandin-associated periorbitopathy resulting from latanoprost use. Patients developed involution of dermatochalasia, blepharoptosis, deepening of orbital sulci, and flattening of lower eyelid bags after a mean usage period of 6 years (3 to 8 years).
Latanoprost can cause PAP, although it has a lower risk and longer latency of onset than those with bimatoprost and travoprost. Clinicians should be aware of this side effect and monitor for signs periodically. Chronic unilateral prostaglandin use may cause unfavorable asymmetry in the appearance of the periorbital area.
