What this Trial Is About
Facial palsy affects between 15 and 40 people per 100,000 and can result from various causes including infections, tumors, trauma, or unknown reasons. The severity and recovery vary, and incomplete recovery impacts quality of life. Current treatments include surgery, physiotherapy, and botulinum toxin injections. This study aims to evaluate how patients with facial paralysis pay attention to faces with abnormal facial movements using eye-tracking technology compared to healthy volunteers. Participants will be recorded performing five facial movements, such as eyelid closure and smiling, using video sequences created with specialized software called Tobii Pro Lab®. The study includes two groups: patients with peripheral facial palsy regardless of severity or prior treatment and healthy volunteers without major facial sequelae. The goal is to quantitatively analyze and compare eye fixation patterns between these groups. During the study, researchers will measure variations in facial fixation and the presence of abnormal facial movements over 30 days. Participants will be asked to perform specific facial movements while being recorded, and their eye movements will be tracked and analyzed. The study involves no masking or randomization and includes adults aged 18 and older. The total duration includes monitoring the primary outcomes related to eye-tracking measurements within 30 days.
