Eye Tracking Study to Evaluate Eye Movement and Visual Attention in Adults with Thyroid-Associated Ophthalmopathy

What this Trial Is About

Researchers are evaluating eye health and visual function in people with Thyroid-Associated Ophthalmopathy TAO, a condition that can cause bulging eyes and limited eye movement. This study aims to use non-invasive eye-tracking technology to measure how TAO affects eye movement and visual attention compared to healthy individuals. The goal is to objectively understand how the disease impacts physical eye function and social behaviors like eye contact. Participants will undergo a single, standardized visit where they will complete a visual function assessment using a desktop high-frequency eye tracker. The test includes calibration to ensure accurate tracking, oculomotor tasks to evaluate eye stability and smooth pursuit ability, and visual attention tasks to record how participants scan static images. This process is non-invasive and takes about 15 to 20 minutes. During the visit, researchers will record gaze patterns and measure outcomes such as smooth pursuit function, central fixation stability, gaze distribution on eye areas, and extraocular muscle thickness. These measures will help quantify the diseases effects. The study will include 100 participants, both patients with TAO and healthy volunteers, aged 18 to 70 years. The entire participation involves this brief assessment without any treatment or further follow-up.
