目的：观察采用智能手机和平板电脑进行精细目力训练对儿童远视性弱视的治疗效果。

方法：本前瞻性研究收集4～6(平均5.20±0.86)岁远视性弱视儿童120例120眼，随机分为治疗组(60例60眼)和对照组(60例60眼)。两组患儿均接受阿托品散瞳验光配镜、单眼遮盖及弱视训练。对照组采用红光闪烁治疗、光栅治疗以及插板、穿珠和穿针等传统精细目力训练。治疗组同样接受红光闪烁及光栅治疗，但传统精细目力训练则以智能手机和平板电脑游戏所取代。每3mo复查1次最佳矫正视力，以评估各组每提升1行LogMAR视力所需治疗时间、基本治愈所需平均治疗时间及疗效。

结果：治疗组每提升1行LogMAR视力所需治疗时间(80.54±30.87d)和基本治愈所需平均治疗时间(15.34±7.24mo)均短于对照组(120.37±60.16d和18.56±10.85mo)，差异均有统计学意义(t=10.24，P<0.05； t=8.57，P<0.05)。治疗组基本治愈40眼，进步16眼，无效4眼； 对照组基本治愈30眼，进步14眼，无效16眼，治疗组疗效显著高于对照组(Z=-2.37， P=0.02)。

结论：使用智能手机和平板电脑取代传统精细目力训练，可较快改善视力并缩短弱视基本治愈所需平均治疗时间，疗效明显，为弱视治疗提供了新的临床训练手段。

METHODS: One hundred and twenty children(120 eyes)with hyperopia amblyopia were randomly divided into two groups in this prospective study. All the children in these two groups received the basic treatments of spectacle correction, penalization therapy and amblyopia trainings. The treatments of red-light blinking and grating as well as traditional fine sight training were used for the children in the control group. However, the smartphones and pads were applied instead of the traditional performances for the fine sight training in the experimental group. Best corrected visual acuity of every child was tested for every 3mo, to observe the time for the visual improvement and efficacy.

RESULTS: In comparison with the control group, significant shorter time(80.54±30.87d, P<0.05)for promoted one line of LogMAR visual acuity and average treatment time(15.34±7.24mo, P<0.05)were harvested in the experimental group. The efficacy in the experimental group was significantly higher than that in the control group(Z=-2.37, P=0.02).

CONCLUSION: The fine sight training with the smartphones and pads can improve vison faster than traditional methods and decrease the time of therapy in children with hyperopia amblyopia, thus providing a new strategy for the treatment of hyperopia amblyopia.
