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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| VR/AR visual training group | Experimental | Wear glasses for correction combined with VR/AR visual training in the first 6 months, and terminate the training for follow-up observation in the last 6 months. Regular follow-up every 3 months, with a total follow-up time of 1 year. |
|
| control group | No Intervention | No intervention, simply wearing glasses for correction, followed up every 3 months for a total of 12 months. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| VR/AR visual training group | Device | Wear glasses for correction combined with VR/AR visual training in the first 6 months, and terminate the training for follow-up observation in the last 6 months. Regular follow-up every 3 months, with a total follow-up time of 1 year. |
| Measure | Description | Time Frame |
|---|---|---|
| changes in stereoscopic vision function after 6 month | Compare whether the intervention group has better stereoscopic vision function than the control group after 6 months | 6 months after baseline |
| changes in stereoscopic vision function after 12 month | Stop the intervention group training after 6 months and observe for another 6 months to see if there will be a decrease in stereoscopic vision function. | 12 month after baseline |
