Effect of Atropine on Pupil Size and Quality of Vision

Summary

This aims to investigated the short-term (12, 16, and 20 h) effects of 0.01% atropine (0.1 mg/ml) on pupil size and subjective quality of vision in participants with myopia. Particpants will receive 0.01% atropine one drop to both eyes before bedtime. Baseline parameters were measured before atropine application. Changes in pupil sizes, under photopic and mesopic conditions, high-order aberration, and tear meniscus height were observed over the next day (12, 16, and 20 h).
