背景:虚拟现实越来越多地应用于视觉治疗。然而,有效性的差异,最佳治疗周期,基于虚拟现实的视觉疗法和传统疗法之间的预后仍然未知。这项研究的目的是比较基于虚拟现实的视觉疗法和基于办公室的聚散度/调节疗法在患有会聚不足或调节功能障碍的年轻人中的有效性。
方法:患者被随机分配到基于虚拟现实的视觉治疗组或基于办公室的聚散度/调节治疗组。两组的视力治疗持续12周(1小时/周)。测量双眼视觉功能(聚散度和调节),并在基线以及治疗6和12周后进行基于主观问卷的评估。
结果:总计,33名收敛功能不全患者和30名调节功能障碍患者完成了研究。经过12周的收敛功能不全的治疗,收敛不足症状调查得分(F2,31=13.704,P<0.001),近收敛点(F2,31=21.774,P<0.001),正融合发散(F2,31=71.766,P<0.001),和近水平盲视(F2,31=16.482,P<0.001)在两组中均显着改善。此外,治疗12周后,两组单眼调节幅度(F2,25=22.154,P<0.001)和单眼调节设施(F2,25=86.164,P<0.001)均有显著改善。两组间单眼调节设施差异有统计学意义(F1,25=8.140,P=0.009),但在其他聚散度和调节功能方面没有(0.098
结论:基于虚拟现实的视觉治疗显著改善了会聚功能不全和调节功能障碍患者的双眼视觉功能和症状,从而表明它的有效性作为一个新的可选或额外的治疗年轻成年人有这些条件。

BACKGROUND: Virtual reality is being increasingly applied in vision therapy. However, the differences in effectiveness, optimal treatment cycle, and prognosis between virtual reality-based vision therapy and traditional therapies remain unknown. The purpose of this
study was to compare the effectiveness of virtual reality-based vision therapy and office-based vergence/accommodative therapy in young adults with convergence insufficiency or accommodative dysfunction.
METHODS: The patients were randomly assigned to either the virtual reality-based vision therapy group or the office-based vergence/accommodative therapy group. The vision therapy lasted 12 weeks (1 h/week) in both groups. Binocular visual functions (vergence and accommodation) were measured and a subjective questionnaire-based assessment was performed at baseline and after 6 and 12 weeks of therapy.
RESULTS: In total, 33 patients with convergence insufficiency and 30 with accommodative dysfunction completed the
study. After 12 weeks of treatment for convergence insufficiency, the Convergence Insufficiency Symptom Survey score (F2,31 = 13.704, P < 0.001), near point of convergence (F2,31 = 21.774, P < 0.001), positive fusional vergence (F2,31 = 71.766, P < 0.001), and near horizontal phoria (F2,31 = 16.482, P < 0.001) improved significantly in both groups. Moreover, the monocular accommodative amplitude (F2,25 = 22.154, P < 0.001) and monocular accommodative facility (F2,25 = 86.164, P < 0.001) improved significantly in both groups after 12 weeks of treatment. A statistically significant difference was observed in monocular accommodative facility (F1,25 = 8.140, P = 0.009) between the two groups, but not in other vergence and accommodative functions (0.098 < P < 0.687).
CONCLUSIONS: Virtual reality-based vision therapy significantly improved binocular vision functions and symptoms in patients with convergence insufficiency and accommodative dysfunction, thereby suggesting its effectiveness as a new optional or additional treatment for young adults with these conditions.
