Summary

This study tested a new questionnaire designed to measure how well babies (0-36 months old) with eye diseases can see, even before they can talk. The goal was to help doctors decide the best time for surgery. The study included 150 children with different eye conditions and checked if the questionnaire was reliable and accurate.
