分析446例共同性斜视水平直肌后退、缩短的手术矫正量.结果:在双内直肌后退术中,学龄前儿童每后退lmm,内直肌(MR)平均矫正2.15°,学龄期儿童为2.06°”/mm,中青年为1.94”/mm.在MR后退或外直肌(LR)缩短术中,学龄前儿童为1.80°/mm,学龄期儿童为2.07°/mm,中青年为1.93°/mm.3组平均MR后退2.05°/mm,LR后退1.35°/mm,并作直线回归方程.MR后退7mm治疗大角度内斜是有效和安全的,并详细讨论了手术矫正量和技巧.
Retrograde and shortened operative corrections were analyzed in 446 patients with common strabismus horizontal rectus.Results: In the retreat of the two rectus muscles, the preschool children retreated by 1mm each time and the rectus muscle (MR) corrected 2.15 ° on average.The children of school age were 2.06 ° "/ mm for young and middle-aged patients, and 1.94 mm / middle-aged for young and middle-aged children. The average age of pre-school children was 1.80 ° / mm for preschool or rectus abdominis LR, 2.07 ° / mm for school-age children and 1.93 ° / mm.3 group, the average MR regression 2.05 ° / mm, LR regression 1.35 ° / mm, and make a linear regression equation .MR 7mm back angle treatment of large angle is effective and safe, and discussed in detail the amount of surgical correction and skills .
