Study Summary

This study evaluated pupil dilation after administration of fixed combination tropicamide-phenylephrine (TR/PH) vs. placebo. Participants attended 3 visits. At each visit, after baseline measurements, either the study drug or placebo was administered to both eyes, then pupil dilation and safety assessments were performed at specific time intervals.

Primary Outcome

Difference in 35-minute pupil diameter vs. baseline measured using pupillometry in highly photopic conditions. Pupil diameter is reported in millimeters. For the change in pupil diameter, larger measurements indicate a better outcome.

Interventions
