摘要
目的 :探讨在弱视的治疗中 ,长期的完全遮盖疗法对弱视儿童屈光状态的影响。方法 :选择双眼均为远视的单眼弱视儿童 5 7例 ,年龄 4～ 8岁 ,平均为 (5 .4± 1.4 )岁 ,按1∶6行完全遮盖疗法 ,疗程 14～ 2 4个月 ,平均 (18± 2 .6 )个月 ,比较双眼年均下降远视屈光度。结果 :被遮盖眼 (健眼 )和对侧眼 (弱视眼 )的年均下降远视屈光度分别为 (0 .4 6± 0 .14 )D和 (0 .2 1± 0 .15 )D ,二者经配对t检验发现 ,差异有显著性 (P <0 .0 5 )。结论 :长期的完全遮盖疗法可加快弱视儿童被遮盖眼远视屈光度下降的速度 ,使屈光参差增大。
Objective:To evaluate the effect of long term complete occlusion therapy on children with hyperopic amblyopia and the changes in refractive status.Methods:57 cases with hyperopia in two eyes and unilateral amblyopia were included in the study. Their ages ranged from 4 to 8 years[mean,(5.4±1.4)years]. Occlusion therapy was scheduled as 1∶6 days. Mean follow up was (18±2.6)months(range 14～24 months).Results:The mean reductions in hyperopia were (0.46±0.14)D and (0.21±0.15)D per year in occluded eyes and contralateral eyes,respectively(P<0.05). Best corrected visual acuity was improved annually by 3 lines on average in amblyopic eyes.Conclusion:Full time occlusion therapy would accelerate the reduction of hyperopia in eyes and enhance anisometropic improvement in children with hyperopic amblyopia.
