Binocul Vis Strabismus Q. 2005;20(1):21-5.
To investigate the final surgical outcome in horizontal strabismus correction, measured in primary position of gaze, in two situations: 1. When surgery was performed only on the horizontal rectus muscles; and 2. When inferior or superior oblique muscle weakening procedures were simultaneously performed.
Two hundred thirty cases were analyzed retrospectively: 172 esotropias (110 without oblique overaction; 23 with inferior oblique overaction; and 39 with superior oblique overaction), and 58 exotropias (25 without oblique overaction; 19 with inferior oblique overaction; and 14 with superior oblique overaction). Initial and final deviations, as well as the amount of correction achieved, was compared in six groups.
No differences in outcomes and final results were found between any of the major or minor groups of patients.
Oblique muscle weakening, in combination with horizontal muscle strabismus surgery did not affect the final results of the horizonal surgery in primary position. This study did suggest that there might not be a need for increasing or decreasing amounts of surgery on the horizontal rectus muscles to correct eso- or exotropia when oblique weakening procedures are included.
研究水平斜视矫正手术在注视原位时的最终手术效果，分两种情况进行测量：1. 仅对水平直肌进行手术时；2. 同时进行下斜肌或上斜肌减弱手术时。
回顾性分析230例病例：172例内斜视（110例无斜肌亢进；23例有下斜肌亢进；39例有上斜肌亢进），以及58例外斜视（25例无斜肌亢进；19例有下斜肌亢进；14例有上斜肌亢进）。比较六组患者的初始和最终斜视度以及矫正量。
在任何主要或次要患者组之间，手术效果和最终结果均未发现差异。
斜肌减弱联合水平肌斜视手术不影响注视原位时水平斜视手术的最终结果。本研究确实表明，当包括斜肌减弱手术时，可能无需增加或减少水平直肌的手术量来矫正内斜视或外斜视。
