PURPOSE:
Strabismus surgery effectively corrects eye alignment, but the spontaneous recovery rate of higher cortical visual functions remains suboptimal postoperatively. This study explores the role of visual function training in promoting post-surgical visual function recovery in strabismus patients of different ages.

METHODS:
Two patients were included: an 18-year-old adolescent and a 5-year-old child. Tertiary visual function changes, including objective deviation angle, fusion range, and stereopsis, were assessed using a synoptophore. Personalized visual function training was implemented, and visual function changes were recorded during the training period.

RESULTS:
Both patients showed significant improvement in visual function after training. For Yang (1 month of training): stereopsis improved from 80" arc seconds to 30" arc seconds (reaching fine stereopsis level); fusion range expanded from 38° to 48° (26.3% increase); objective deviation angle adjusted from -2° to +5°. For Chang (2 months of training): random-dot stereopsis recovered from "absent" to 30" arc seconds; Titmus near stereopsis acuity improved from 100" arc seconds to 32" arc seconds (68% improvement); fusion range peaked at 30°, with enhanced sensitivity to random-dot stereopsis plates.

RESULTS:

Both patients showed significant improvement in visual function after training. For Yang (1 month of training): stereopsis improved from 80" arc seconds to 30" arc seconds (reaching fine stereopsis level); fusion range expanded from 38° to 48° (26.3% increase); objective deviation angle adjusted from -2° to +5°. For Chang (2 months of training): random-dot stereopsis recovered from "absent" to 30" arc seconds; Titmus near stereopsis acuity improved from 100" arc seconds to 32" arc seconds (68% improvement); fusion range peaked at 30°, with enhanced sensitivity to random-dot stereopsis plates.

CONCLUSIONS:
Visual function training effectively promotes binocular vision recovery after strabismus surgery, particularly in enhancing stereopsis acuity. Both children in the critical period of visual development and adolescents at the end of the plasticity window can benefit from systematic training, achieving significant improvement or reconstruction of stereoscopic vision. It is recommended to incorporate visual function training as an important component of routine postoperative treatment for strabismus to improve patients' long-term visual health and quality of life.
