摘　　要：目的观察A-V综合征患者术后立体视重建的影响因素。方法 A-V综合征住院患者共97例,V征71例,其中外斜V征48例,内斜V征23例,平均年龄6.3岁;A征26例,其中外斜A征21例,内斜A征5例,平均年龄5.9岁,随访8～16周,平均10.7周。术前、术后采用同视机和Titmus分别测定正下方的远、近立体视。观察指标包括:发病年龄、病程、术后眼位和水平斜视类型。结果 97例患者中,术后正前方及下方均正位的患者共88例,术后分别有27例(30.68%)和35例(39.77%)获得了远立体视和近立体视。术后远、近立体视获得比率≤3岁发病组(12.00%、20.00%)低于>3岁发病组(55.26%、65.79%,均为P<0.05);病程≤2a患者的术后获得远、近立体视的比例分别为48.48%、69.70%,明显高于病程>2a的患者(20.00%、21.82%,均为P<0.05);外斜A或V征组术后的远、近立体视获得比例分别为34.43%、18.03%,要高于内斜A或V征组(22.22%、44.44%),组间近立体视比较差异有统计学意义(P<0.05),远视力比较差异无统计学意义(P>0.05)。结论 A-V综合征术后立体视的重建与发病年龄和病程相关,因此,早期发现、正确地诊断与治疗有助于双眼视功能的恢复。Objective To observe the influence factors of A and V restitution stereoacuity restitution after surgery.Methods About 97 cases with A-V syndrome were studied,including 71 cases with V syndrome（exotropia V syndrome in 48 cases and esotropia V syndrome in 23 cases） for average age of 6.3 years,and 26 cases with A syndrome（exotropia A syndrome in 21 cases and esotropia A syndrome in 5 cases） for average age of 5.9 years.All cases were followed up for 8 weeks to 16 weeks,average in 10.7 weeks.Near and far stereopsis were examined with synoptophore and Titmus at pre-and post-operation in each group.The influence factors included age of onset,course,postoperative position of eye and squint type.Results About 88 of 97 cases were obtained orthotropia on right front and lower position.In the 88 cases,there were 27 cases（30.68%） obtained far stereopsis and 35 cases（39.77%） obtained near stereopsis.In age of onset group,the obtained ratios of far and near stereopsis were 12.00% and 20.00% in ≤3 years old group,which were lower than 55.26% and 65.79% in ≥3 years old group（both P0.05）.For course,the obtained ratios of far and near stereopsis were 48.48% and 69.70% in ≤2 years group,which were higher than 20.00% and 21.82% in ≥3 years group（both P0.05）.The obtained ratios of far and near stereopsis for exotropia A and V syndrome were 34.43% and 18.03%,which were higher than 22.22% and 44.44% for esotropia A and V syndrome.There was statistical difference in near stereopsis among groups（P0.05）.No difference was found in far stereopsis among groups（P0.05）.Conclusion Age of onset and course are related with the stereopsis restitution for A and V syndrome patients,so correct treatment and diagnosis early are benefit to obtain the stereopsis for A and V syndrome patients.
