Abstract：Objective To analyze the efficacy of 4D digital orthoptics combined with conventional therapy for anisometropic amblyopia in children and its impact on visual acuity and accommodative function of the amblyopic eye.Methods A retrospective analysis was conducted on the clinical data of 150 children with anisometropic amblyopia admitted to Women's Hospital of Nanjing Medical University(Nanjing Women and Children's Healthcare Hospital)from October 2021 to November 2024.The patients were divided into the combined group(76 cases)and the control group(74 cases).The control group was treated with conventional therapy,while the combined group was treated with 4D digital orthoptics combined with conventional therapy.The clinical efficacy,the rate of abnormal stereoscopic vision turning normal,and the best corrected visual acuity,refractive error,and accommodative function(accommodative amplitude,accommodative facility,and accommodative lag)before and after treatment were compared.Results The total effective rate in the combined group was significantly higher than that in the control group(94.74%vs 83.78%,P<0.05).After treatment,the rate of abnormal stereoscopic vision turning normal in the combined group was significantly higher than that in the control group(85.53%vs 56.76%,P<0.05).After treatment,the best corrected visual acuity of children in both groups significantly increased,and the spherical equivalent refraction significantly decreased,with the combined group showing better outcomes in these indicators than the control group(P<0.05).After treatment,the accommodative amplitude and accommodative facility of children in both groups significantly increased,and the accommodative lag significantly decreased,with the combined group demonstrating superior results in these parameters compared to the control group(P<0.05).Conclusion 4D digital orthoptics combined with conventional therapy shows significant clinical efficacy in children with anisometropic amblyopia.It not only effectively improves the visual acuity of the amblyopic eye but also enhances the accommodative function of the amblyopic eye,indicating certain clinical application value.
