弱视斜视临床与发病机理的研究

本文报告了弱视931例(1332只眼)的远期疗效,结果表明视力提高与年龄、弱视深度、弱视类型等因素有明显关系。治愈的弱视患者中有81.07％建立立体视,弱视深度与体视有关,斜视性弱视获立体视率明显低于屈光不正和屈光参差两组。体视建立随年龄增长而逐渐发育。弱视复发是治疗中的一个重要问题,随访3年以上者无1例复发。同时在国内外首次3年治愈的随访期限。用多导视诱发电位地形图的研究结果提示:(1)内斜弱视的弱视眼鼻侧视网膜呈抑制现象;(2)恒定性外斜弱视颞侧视网膜抑制;(3)间歇性外斜弱视和屈光参差弱视眼未见半侧视网膜抑制;(4)内斜弱视眼对侧眼为非“正常眼”。

A CLINICAL HND PATHOGENIC STUDYOF AMBLYOPIA AND STRABISMUS

The goal of amblyopia management is to increase vision and to obtain stereopsis. Nine hundredand thirty-one cases(1332 eyes) of amblyopia and the results of development of stereopsis are reported.This article reports the recent study of amblyopia and emphasizes current concepts in evaluation of the-rapeutic efficiency. 73.32 per cent of the cases achieved 1.0 of vision, with statistically significantdifference between the young group and the old group. The severity of initial amblyopia markedly in-fluenced the curative ratio, and significant difference was found in increase of vision between the gro-ups with ametropia and with anisometropia of strabismus. Stereoacuity was esfablished In 81.07 percent of the patients the severity of amblyopia, ocular alignment and age are closely related to the suc-cess rate of establishing stereopsis. Recurrence of Amblyopia is one of important problem in treatmentof amblyopia. In a total of 453 cured patients who have been followed for more than 3 years nonerecurrence has been noted. The authors feel that a regular follow-up term of amblyopia would be 3years.Examination with multi-channel VEPs topography showed: a phenomenon of nasal retinal sup-pression was observed in amblyopic eyes of esotropia and a temporal retinal suppression phenomenonwas found in constant exotropic eyes, but half retinal suppression phenomena were not found in inter-mittent exotropic and anisometropic amblyopic eyes. The contralateral non-amblyopic eyes of eyes inesotropic amblyopia may not actually be "normal".
