Certain strabismus operations require a thorough knowledge of the anatomy of rectus muscle insertions. Earlier anatomical studies were based on a small sample size and did not use precise microscopic techniques for measurements. To obtain accurate measurements of rectus muscle insertion relationships, 100 consecutive normal adult autopsy eyes were examined with a Vernier caliper and a dissecting microscope for high magnification. Statistical analysis of these data provided a set of normal values for (1) distances from anterior and posterior limbus to rectus muscle insertions, (2) distances between anterior and posterior limbus, (3) length of line ("width") of rectus muscle insertions, and (4) distances between rectus muscle insertions. Although most of the determinations were somewhat similar to older previous studies, statistically they were significantly different. The ophthalmologist can make use of the revised set of figures for rectus muscle insertion relationships in operations such as transposition procedures for A-V patterns and cranial nerve palsies, large recessions, and advancements in reoperations after recessions.
某些斜视手术需要全面了解直肌附着点的解剖结构。早期的解剖学研究基于小样本量，且未使用精确的显微技术进行测量。为了获得直肌附着点关系的准确测量值，使用游标卡尺和解剖显微镜对100只连续的正常成年尸眼进行高倍检查。对这些数据的统计分析提供了一组正常值，用于（1）从角膜前后缘到直肌附着点的距离，（2）角膜前后缘之间的距离，（3）直肌附着点的线长（“宽度”），以及（4）直肌附着点之间的距离。尽管大多数测定结果与以前的旧研究有些相似，但在统计学上它们有显著差异。眼科医生可以在诸如A-V型和脑神经麻痹的转位手术、大的后徙术以及后徙术后再次手术中的前徙术等手术中利用这组修订后的直肌附着点关系数据。
