Official title
A Randomized, Double-Masked, Dose-Ranging Study of Atropine Sulfate Ophthalmic Solution for the Treatment of Symptoms of Epiphora
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to learn if low-dose atropine eye drops work to reduce excessive watery eyes (epiphora) in adults. It will also learn about the safety of the eye drops. The main questions it aims to answer are: Do the eye drops reduce how often participants have watery eyes? What medical problems do participants have when taking the eye drops? Researchers will compare two strengths of the eye drops (0.005% and 0.01%) to see whether one works better than the other and whether the lower strength works as well as the higher one. Participants will: * Use the assigned eye drops in the affected eye(s) for one week * Visit the clinic twice for checkups and eye tests * Receive a follow-up phone call about two weeks after starting, to check on any symptoms
