ClinConnect Summary

This clinical trial is testing a new way to check how well young children, including those with special needs, can see. Traditional eye tests can be hard for babies, toddlers, and children with developmental disabilities to complete. This study uses a special eye-tracking system combined with advanced computer technology to measure how clearly and widely children can see, without needing complicated or uncomfortable tests. The goal is to create a simple, gentle eye screening method that works well for all young children, helping to spot vision problems early.

Children under 3 years old, preschoolers aged 3 to 5 who are developing typically, and children up to 12 years old with physical or mental disabilities may be able to join, as long as their caregiver agrees. Adults between 18 and 70 years can also participate for comparison. Children with serious eye conditions or who are unable to wear glasses during the test may not qualify. During the study, children will have their eye movements recorded while they look at different things on a screen. This is a noninvasive process, meaning it doesn’t cause pain or discomfort, and helps doctors better understand each child’s vision in a way that suits their individual needs.
