Lash Ptosis Caused by Latanoprost

In a 2005 observational case report, a 61-year-old man with ocular hypertension developed trichomegaly and bilateral lash ptosis after using latanoprost in both eyes (OU). Despite discontinuing the medication, the lash ptosis persisted, leading to the performance of anterior lamellar repositions 6 months later. At the 8-month follow-up post-surgery, the patient's eyelid position had normalized, but there was only a slight reduction in trichomegaly. The study concluded that lash ptosis is a potential side effect of latanoprost therapy.
