The localisation and definition of the capsule of Tenon insertion on the rectus muscles is of prime importance to the strabismus surgeon. The depth of the superior sub-Tenon space was measured on 22 adult human eyes after fixation in formalin. Although the measurements revealed major differences between the eyes, the following results were found: inferior rectus muscle = 7.8 mm +/- 1.79 (5.2-13.0), medial rectus = 12.6 mm +/- 2.15 (8.4-17.2), superior rectus muscle = 16.7 mm +/- 2.39 (12.7-21.5), and lateral rectus muscle = 19.0 mm +/- 2.19 (14.5-22.0). Histological studies of 2 other human eyes confirmed the notion of a band of insertion on rectus muscles as the posterior limit of the sub-Tenon space. As far as this insertion, the capsule of Tenon is a dense connective tissue composed of many collagen and elastin fibers, but after the band insertion, it becomes virtual through its fusion with the perimysium of the rectus muscle.
对于斜视外科医生而言，直肌上眼球筋膜囊插入处的定位与界定至关重要。在22只经福尔马林固定的成人眼球上测量了眼球筋膜下间隙的深度。尽管测量结果显示各眼球之间存在较大差异，但仍得出以下结果：下直肌为7.8毫米±1.79（5.2 - 13.0），内直肌为12.6毫米±2.15（8.4 - 17.2），上直肌为16.7毫米±2.39（12.7 - 21.5），外直肌为19.0毫米±2.19（14.5 - 22.0）。对另外2只人眼进行的组织学研究证实了直肌上存在一条插入带作为眼球筋膜下间隙后界的观点。就该插入处而言，眼球筋膜囊是由许多胶原纤维和弹性纤维组成的致密结缔组织，但在插入带之后，它通过与直肌肌外膜融合而变得不明显。
