NCT ID NCT03146078

Summary

This study aims to understand how vision declines over time in people with USH2A gene mutations, which cause Usher syndrome type 2a and a form of retinitis pigmentosa. Researchers are following 127 patients for up to 9 years, measuring their vision and retinal health with various tests. The goal is to gather detailed information to help design and measure the effectiveness of future treatment trials.
