在治疗期间弱视眼的屈光矫正问题

Refractive correction of hyperopia during the treatment of amblyopia

目的 :探讨治疗期间 ,弱视眼的远视性屈光不正应该欠矫或是全部矫正。对象和方法 :两组单眼弱视 ,第一组 ,全矫 ,70例 ,弱视眼的远视全部矫正 ;第二组 ,欠矫 ,68例 ,弱视眼的远视欠矫 + 1 0 0～ + 3 5 0D .S .,平均 + 1 75D .S .。戴镜之后 ,采用传统遮盖疗法结合其他方法治疗弱视。观察治疗前后的眼位变化。结果 :全矫组病人的弱视眼视力恢复到 1 0 ,健眼遮盖的时间平均是 9 0个月 ,而欠矫组需要 11 1月。全矫组遮盖时间平均缩短2 1个月。在治疗期间 ,两组病人中没有出现外斜视。结论 :弱视眼的调节功能降低 ,调节幅度变小。治疗期间 ,远视全部矫正 ,能缩短疗程 ,有利于弱视的恢复。

To explore the importance of full correction o f hyperopia during the treatment of amblyopia. Methods:A retrospective study on the influence of correcti ng refractive error on the treatment of amblyopia was run on 138 cases of hyperopic amblyopia.Those patients were divided into two groups:the first group,70 patients,full optical correction of the amblyopic eyes;the second group,68 patients,under optical correction (lack of 1.00～3.00DS) of the amblyopic eyes. Results:The improvement in vision was directly related to the adequacy of correction of hyperopia.The treatment for first group took 9 months;the second group took 11.1 months. Conclusions:The results suggest that the importance of ful l optical correction of hyperopia for the amblyopic eyes should be stressed during the occlusion therapy of amblyopia,because the amblyopic eyes have not full accommodation under monocular condition.
