5. Study Description

Brief Summary
Our project is a 24-month longitudinal randomized controlled trial that aims to investigate the myopia development after topical application of 0.01% atropine in children with either fast or slow myopia progression classified according to their initial electro-retinal responses. This will help elucidate the effectiveness of using low concentration atropine for myopia control in children with different myopia progression rates.
