【摘要】:目的探讨不同年龄组共同性外斜视行双眼外直肌后徙术后矫正视力,眼位及双眼单视功能的变化。方法将81例不同年龄组共同性外斜视患者分三组:3~6岁组31例,平均(4.1±0.3)岁;7~12岁组27例,平均(6.2±1.8)岁;≥13岁组23例,平均(25.4±2.2)岁,三组患者均行双眼外直肌后徙术后比较矫正视力变化、正位率、近距离立体视功能的提高率。结果 (1)矫正视力:仅7~12岁组中2例术后矫正视力提高,余均未变化;(2)正位率:术后6个月时,3~6岁组为97%,7~12岁组为93%,≥13岁组为91%,三组结果经卡方检验:X~2=5.815,P0.05,差异有统计学意义;(3)近立体视提高率:3~6岁组为97%,7~12岁组为37%,≥13岁组为4%,三组结果经卡方检验:X~2=12.554,P0.05,差异有统计学意义。结论手术时机对正位率及双眼单视功能重建影响大,应早期行手术治疗;双眼外直肌后徙术仍存在一定的欠矫率。

Methods Eighty-one patients with concomitant exotropia in different age groups were divided into three groups: 31 patients were 6 years old, with an average age of 4.1 卤0.3 years. There were 27 cases (mean 6.2 卤1.8) years old in the group of 12 years old. 23 cases (mean 25.4 卤2.2) years old in the group of 鈮,
