影响弱视儿童双眼视觉功能重建的多因素分析

目的对影响弱视患儿双眼视觉功能重建的多个因素进行分析。方法对192例就诊于我院斜弱视专科门诊，坚持治疗且视力恢复正常的弱视患儿进行双眼视觉检查，并记录其性别、初诊时年龄、视力正常时年龄、治疗时间、弱视程度及弱视类型,通过logistic回归分析这些因素与患儿双眼视觉功能重建的关系，结果在192例临床治愈的弱视患儿中，初诊时具有立体视功能者7例（400”者1例，占0．52％；800”者6例，占3．13％；共计3．65％），融合功能者22例（11．46％），同时视功能者76例（39．58％），无功能者87例（45.31％）。视力正常时具有立体视功能者61例（≤60”者27例，占14．06％;100”～200”者21例,占10．94％：400”～800”者13例，占6．77％；共计31．77％），融合功能者104例（54．17％），同时视功能者16例（8．33％），无功能者11例（5．73％）。对同时视有影响的因素为弱视类型（屈光不正性弱视）、治疗时间和弱视程度；对融合有影响的因素为治疗时间、初诊年龄、弱视类型（斜视性弱视）和弱视程度；对立体视有影响的因素为视力正常时年龄、初诊年龄、弱视类型（斜视性弱视）和弱视程度。结论弱视类型、弱视程度、初诊年龄、视力正常时年龄和治疗时间是影响双眼视觉功能重建的有关因素，其中对同时视、融合和立体视形成影响最大的因素分别为弱视类型、治疗时间和视力正常时年龄。

Multiple flactor analysis of the reestablishment of binocular vision in amblyopic children

Objective To analyze the multiple factors which affect the reestablishment of binocular vision in amblyopic children. Methods One hundred ninetv-two children with amblyopia were examined for binocular function once their visual acuity had recovered after treatment. Their sex. their age at the time of their first visit to a doctor, the duration of treatment, the age when visual acuity recovered, and the type and severity of amblyopia were recorded. These factors and their relationship with the reestablishment of binocular vision were analyzed by logistic regression analysis. Results Of the 192 children, 7 children had stereopsis （3.65%） on the first visit-one with 400 seconds of arc and 6 with 800 seconds-22 had fusion （11.46%）, 76 had simuhaneous perceptual function （39.58%）, while 87 had no binocular vision at all （45.31%）. Once their visual acuity had recovered to a normal level, 61 children had stereopsis （31.77%）-27 with stereopsis of ≤60 seconds of arc, 21 from 100 to 200 seconds, and 13 from 400 to 800 seconds-104 had fusion （54.17%）, 16 had simuhaneous perceptual function （8.33%）, while only 11 had no binocular vision at all （5.73%）. The factors that influenced simuhaneous perception were the duration of therapy and the type and severity of amblyopi-a. The factors that influenced fusion were the duration of therapy, age at the time of the first visit to a doctor, and the type and severity of amblyopia. The factors that influenced stereopsis were the age when visual acuity recovered, age at the time of the first visit to a doctnr, and the type and severity of amblyopia. Conclusion The factors related to the reestablishment of binocular vision were the type and severity of amblyopia, age at the time of the first visit to a doctor, the duration of therapy and the age when visual acuity recovered. The most important factors that affect degree of simultaneous perception, fusion and stereopsis were the type of amblyopia, the duration of therapy and the age that visual acuity rec
