TLDR Latanoprost eye drops may cause skin depigmentation.
This article reports on a case of skin depigmentation in a patient using latanoprost eye drops for glaucoma treatment. The patient's skin depigmentation did not reverse after discontinuing other medications, but did show some improvement after discontinuing latanoprost. The article suggests that clinicians should be aware of this potential adverse effect and monitor for signs accordingly. The underlying mechanism behind these observations remains unknown, but it was hypothesized that individual follicular responses to prostaglandins may differ during the anagen phase of the cell cycle.
