摘要
目的：探究单眼部分遮盖与双眼交替遮盖治疗屈光不正性弱视儿童的疗效，及对其立体视锐度(stereoacuity，SA)的改善作用。方法：选取2018年4月至2019年4月辽阳市中心医院收治的92例(168只患眼)屈光不正性弱视儿童，按随机数表法将所有患者均分为研究组(86只患眼)与对照组(82只患眼)。研究组采用单眼部分遮盖方式进行治疗，对照组采用双眼交替遮盖方式进行治疗，比较两组患儿治疗后的疗效，治疗前后患儿的视力水平、SA、弱视眼的调节幅度(amplitude of accommodation，AMP)和调节灵敏度(accommodating facility，AF)。结果：治疗后，研究组患儿的总有效率为89.53%，显著高于对照组(75.61%，P<0.05)；研究组患儿治疗后1周、4周、3个月、6个月视力较治疗前依次提升(P<0.05)，研究组患儿的视力水平恢复程度显著优于对照组(P<0.05)；治疗后，两组患儿的SA显著降低(P<0.05)，AMP和AF均显著上升(P<0.05)，且研究组治疗后与对照组对比差异有统计学意义(P<0.05)；治疗后，研究组患儿弱视眼中立体视正常率为74.42%，显著高于对照组(54.88%，P<0.05)，研究组患儿恢复到SA正常水平的眼数显著高于对照组(44眼 vs 23眼；P<0.05)。结论：应用单眼部分遮盖方式治疗屈光不正性弱视儿童的疗效更佳，可利于提升患儿的视力水平，提升患儿的SA，有效改善患儿的AMP和AF，是一种安全有效的治疗方法。

Abstract
Objective: To investigate the efficacy of monocular partial covering and binocular alternating covering in the treatment of children with ametropic amblyopia, and the positive effects on stereoacuity (SA). Methods: A total of 92 patients (168 affected eyes) with ametropic amblyopia in our hospital from April 2018 to April 2019 were selected. All patients were divided into study group (46 cases, 86 affected eyes) and control group (46 cases, 82 affected eyes) according to the method of random number table. Study group was treated with monocular partial covering while control group was treated with binocular alternating covering. The efficacy, visual acuity level, SA, amplitude of accommodation (AMP) and accommodation facility (AF) of amblyopic eyes before and after treatment were compared between the 2 groups. Results: After treatment, the total effective rate in study group was significantly higher than that in control group (89.53% vs 75.61%) (P<0.05). The visual acuity in study group improved sequentially at 1 week, 4 weeks, 3 months, and 6 months after treatment compared with that before treatment (P<0.05), and the recovery of visual acuity in study group was significantly better than that in control group (P<0.05). After treatment, the SA in the two groups was significantly decreased (P<0.05) while the AMP and AF were significantly increased (P<0.05), and the indexes in study group after treatment were significantly different from those in control group (P<0.05). After treatment, the normal rate of SA of amblyopic eyes in study group was significantly higher than that in control group (74.42% vs 54.88%) (P<0.05), and the number of eyes recovering to the normal level of SA in study group was significantly higher than that in control group (44 eyes vs 23 eyes) (P<0.05). Conclusion: Monocular partial covering has better efficacy in the treatment of children with ametropic amblyopia, and it can help to improve their visual acuity and SA, and effectively promote their AMP and AF. Therefore, it is a safe and effective method.
