Title : Retrospective comparison of efficacy of virtual reality based vision therapy and dichoptic therapy in children with anisometropic amblyopia who had previously undergone patching therapy
Abstract:
Study design: Retrospective comparative study
Purpose: To evaluate the efficacy of two types of vision therapy for amblyopia in children with anisometropic amblyopia who had previously undergone patching therapy.
Methods: Children 5-18 years of age diagnosed with mild to moderate anisometropic amblyopia who underwent either artificial intelligence powered virtual reality based gamified mono ocular suppression therapy (BeeVee)or gamified dichoptic therapy (Bynocs) from January 2024 to May 2025 were included. Best corrected visual acuity (BCVA) before and after treatment was analysed.
Results: There were 23 patients in each group. The mean age was comparable in both groups. (11.47 years in BeeVee group; 12.26 years in Bynocs group) The average pre and post BCVA was 0.461 logMAR and 0.378 logMAR in BeeVee group (p<0.001); 0.452 logMAR and 0.304 logMAR in Bynocs group (p<0.001). Average improvement post treatment was 0.083 logMAR in BeeVee group and 0.147 logMAR in Bynocs group (p = 0.7) which was not statistically significant.
Conclusion: There is no statistically significant difference in average improvement between the two groups.
Clinical Implication: Both types of vision therapy seem to be equally effective in the treatment of anisometropic amblyopia in children who had previously tried patching therapy.
