背景:在这项研究中,我们的目的是确定我们的视力治疗计划对7至10岁表现出对常规治疗不再有反应的双侧弱视患者的效果。
方法:对2016年至2019年在中国医科大学附属医院接受视力治疗的7~10岁双侧弱视儿童进行回顾性分析。年龄和视力匹配的双侧弱视者作为对照组。通过兼职修补和完全屈光矫正,两组的视力在3个月以上均无改善。最初和最终的视力,立体视觉,和屈光状态进行了分析。
结果:这里,治疗组15例,对照组16例。在端点,研究组显示出BCVA的显着改善,对照组的平均logMAR为0.32±0.15(3行改善),而logMAR为0.003±0.19(几乎没有改善)(p<0.001)。治疗的益处在治疗后的前3个月最明显(p<0.001),并持续到终点。立体灵敏度也从190.00±163.34提高到85.00±61.24弧秒,提高了55.26%。
结论:视觉疗法,包括矫正治疗,知觉学习和二叉训练,是一项成功的计划,可以提高对常规治疗无反应的7至10岁双侧弱视儿童的视力和立体敏锐度。
BACKGROUND: In this study we aim to determines the effect of our vision therapy program for 7- to 10-year-old patients who exhibit bilateral amblyopia that is no longer responsive to conventional treatment.
METHODS: Children with bilateral amblyopia between the ages of 7 and 10 treated with vision therapy at the
China Medical University Hospital between 2016 and 2019 were retrospectively reviewed. Age and visual acuity-matched bilateral amblyopes are included as a control group. The visual acuity for both groups showed no improvement for more than 3 months with part-time patching and full refraction correction. The initial and final visual acuity, stereopsis, and refractive status were analyzed.
RESULTS: Here, 15 cases were included as the treatment group and 16 cases as a control group. At the endpoint, the study group shows a significant improvement in BCVA, with a mean of 0.32 ± 0.15 logMAR (3 lines improvement) versus 0.003 ± 0.19 logMAR (nearly no improvement) for the control group (p < 0.001). The benefits of treatment are most obvious in the first 3 months after treatment (p < 0.001) and last until the end point. Stereoacuity also improves from 190.00 ± 163.34 to 85.00 ± 61.24 arc seconds, which is a 55.26% improvement.
CONCLUSIONS: Vision therapy, comprising orthoptic therapy, perceptual learning and dichoptic training, is a successful program for increasing visual acuity and stereoacuity in 7- to 10-year-old children with bilateral amblyopia that is unresponsive to conventional treatment.
