Inclusion criteria

Inclusion criteria: 1. aged 6 to 18 years (including 6 and 18 years), regardless of gender 2. diagnosed with intermittent exotropia and treated with strabismus correction surgery, 1 month postoperatively, with a visual distance exotropia of 10? to 30? measured by alternate trigeminal masking test after covering the non-dominant eye for 30 minutes (if the patient has uncorrected refractive error, the refractive error must be corrected for at least one week after the examination); 3. in-office control scores of 1~3 for both distance and near vision (measured 3 times by the same examiner within 30 minutes, with at least 2 scores meeting the requirements; if the patient has uncorrected refractive error, the refractive error must be corrected after at least one week of examination); 4. no previous strabismus-related treatment other than correction of refractive error and strabismus surgery; 5. best corrected visual acuity in both eyes = 0.8 with a difference of < 2 lines; 6. post-ciliary muscle palsy optometry, equivalent spherical lenses in both eyes are between -6.00D and 0, and the difference is less than 2.50D; 7. no previous visual function training of any kind; 8. Patients and their guardians understand the content of the program, and those who need visual function training can carefully follow the requirements of the medical prescription to complete visual function training and can regularly attend follow-up examinations.
