Visual Functions

The goal of this clinical tral is to investigate that if VR/AR visual training can improve the visual function in children with intermittent exotropia. The main question it aims to answer is : Does the VR/AR visual training can enhance stereoscopic vision function in children with intermittent exotropia. Researchers will compare intervention group to control group to see if VR/AR visual training could enhance stereoscopic vision function in children with intermittent exotropia. Participants will: The intervention group will receive 20 minutes of VR/AR visual training once a day for a period of one year. Follow up check ups at the hospital every 3 months. Keep a diary of the values of stereoscopic vision function and Newcastle Control Score.
