ClinConnect Summary

This clinical trial is exploring whether virtual reality (VR) and augmented reality (AR) visual training can help improve vision in children with a condition called intermittent exotropia, which causes one eye to turn outward at times. The main question the researchers want to answer is if this type of training can enhance the ability to see in three dimensions, known as stereoscopic vision.

Children aged 6 to 14 who meet certain criteria may be eligible to participate. To qualify, they need to have a specific type of eye misalignment and meet certain vision standards. Participants in the study will receive 20 minutes of VR/AR visual training each day for a year and will have check-ups at the hospital every three months to track their progress. It's important to note that children who have other eye conditions or certain health issues may not be eligible. Parents and guardians must agree to let their child participate and sign a consent form. This trial is currently not yet recruiting participants.
