Abstract

PURPOSE

The hypothesis that the extraocular muscle insertion distance and muscle width may be associated with the type and size of deviation was tested.

METHODS

This was a prospective study of 129 patients who had surgery for horizontal strabismus or retinal detachment. The insertion distances and widths of the medial rectus (MR) and lateral rectus (LR) muscles were measured intraoperatively in esotropia, exotropia, and buckling surgery (control group) patients. Statistical analysis was performed to compare measured factors between the groups.

RESULTS

Median medial and lateral muscle insertions were 5.7 and 6.9 mm in esotropia (ET), 6.0 and 7.1 mm in exotropia (XT), and 5.5 and 6.7 mm in the control groups (p > 0.05). The widths of the medial and lateral muscles ranged from 7.0 to 13.0 mm in ET and XT groups and from 9.5 to 11.0 mm in the control group (p > 0.05). Muscle insertion distance and LR muscle width were not correlated with deviation size. Only the MR muscle width was positively correlated with the deviation size.

CONCLUSIONS

Insertion distances of the medial and LR muscles are not statistically different in ET, XT, and control patients. Only MR muscle width was affected by the size of the deviation in ET patients.

摘要

目的

检验眼外肌附着点距离和肌肉宽度可能与斜视类型及大小相关的假说。

方法

这是一项对129例行水平斜视手术或视网膜脱离手术患者的前瞻性研究。术中测量了内斜视、外斜视及巩膜扣带术(对照组)患者的内直肌(MR)和外直肌(LR)的附着点距离及宽度。进行统计分析以比较各组间的测量因素。

结果

内斜视(ET)患者内、外直肌附着点的中位数分别为5.7和6.9mm,外斜视(XT)患者为6.0和7.1mm,对照组为5.5和6.7mm(p>0.05)。ET组和XT组内、外直肌宽度范围为7.0至13.0mm,对照组为9.5至11.0mm(p>0.05)。肌肉附着点距离和LR肌宽度与斜视大小无关。仅MR肌宽度与斜视大小呈正相关。

结论

ET、XT和对照组患者的内直肌和LR肌附着点距离无统计学差异。仅ET患者的MR肌宽度受斜视大小影响。
