Abstract

Objective To compare the influences of three inferior oblique surgeries on horizontal, vertical and rotary eye positions. Methods Fifty-one cases of inferior oblique (IO) muscles overaction who underwent the weaken surgery alone were collected retrospectively. There were three surgical methods underwent: recessions of IO (Group A, 15 cases), myectomy of IO (Group B, 23 cases) and transposition of IO (Group C, 13 cases). Results The influences on horizontal position in group A, B, C were not different(P >0.05). The influences on vertical position were 7.5△±3.5△, 8.1△±2.9△, 12.8△±3.1△ in group A, B, C, respectively, and there was no significant differenc between group A and B (P >0.05), and there were significant differences between group C and A/group C and B (P 0.05). Conclusions In efficiency of influence to eye positions, both recession and myectomy are equal. There is few influence to the horizontal eye position in these three surgery methods. Transposition of the IO strikes the greatest influence to the vertical eye position. All three surgery methods have the similar influence to rotary position. Key words: Inferior oblique overaction; Recession; Myectomy; Transposition

三种下斜肌手术的比较

目的比较三种下斜眼手术对水平、垂直和旋转眼位的影响。方法回顾性分析51例单独行下斜肌弱化手术的下斜肌过度活动的病例。采用三种手术方式:内眦赘肉切除(A组，15例)、内眦赘肉切除(B组，23例)和内眦赘肉转位(C组，13例)。结果A、B、C组对水平体位的影响无显著性差异(P < 0.05)。A、B、C组对垂直体位的影响分别为7.5△±3.5△、8.1△±2.9△、12.8△±3.1△，A、B组间差异无统计学意义(P < 0.05)， C组与A/ C、B组间差异有统计学意义(P < 0.05)。结论在对眼位的影响方面，切除与切除对眼位的影响是相等的。三种手术方式对水平眼位影响不大。眼内移位对眼的垂直位置影响最大。三种手术方式对旋转位置的影响相似。关键词:下斜肌过动;经济衰退;肌切除术;换位
