目的探讨A-V型斜视的病因、临床特点、手术矫正效果及手术方式。方法分析209例A-V综合征患者的临床表现、手术方式及治疗效果;所有患者依据是否伴有斜肌功能异常、原在位水平斜视及双眼单视功能情况行斜肌减弱术或/和水平肌手术,术后观察眼位、斜肌功能及双眼单视功能,随访3～24月,平均12月。结果A-V型斜视占同期斜视患者29.9%;其中,V型外斜占55.8%,A型外斜占9.1%,V型内斜占29.1%,A型内斜占6%;术后178例(85.1%)正位,192例(91.8%)A-V征消失,术后获得立体视功能者160例(76.5%),包括术前16例具有立体视患者。结论A-V型斜视是一种常见的斜视类型,斜肌功能异常是发病的主要原因,原在位常合并水平斜视;根据是否伴有斜肌功能异常及双眼单视功能情况选择手术方式,多可获得较为满意的效果。
Objective To investigate the etiology, clinical features, surgical correction and operation of A-V strabismus. Methods The clinical manifestations, surgical modalities and therapeutic effects of 209 patients with AV syndrome were analyzed. All patients underwent oblique reduction and / or horizontal muscle weakness according to whether they had oblique dysplasia, original horizontal strabismus and binocular single vision function Surgery, postoperative eye position, oblique muscle function and monocular binocular function, followed up for 3 to 24 months, an average of 12 months. Results AV strabismus accounted for 29.9% of patients with strabismus in the same period. Among them, 55.8% were V-type oblique, 9.1% were A-type oblique, 29.1% were V-type oblique, and 6% were Type A oblique. Postoperative 178 85.1%) were anastomosed and 192 patients (91.8%) had AV sign disappeared. There were 160 patients (76.5%) with stereopsis after operation, including 16 patients with stereopsis before operation. Conclusions AV strabismus is a common type of strabismus. Abnormal oblique dysplasia is the main cause of morbidity. The original strabismus is often associated with horizontal strabismus. According to whether the oblique operation is associated with oblique dysfunction or binocular single vision, Get more satisfactory results.
