The tendon sheath of the superior oblique muscle was identified in 30 adult orbits. This sheath is composed of the fasciae of the superior levator palpebrae muscle and the superior rectus muscle and their intermuscular septum. In addition, fascia of the superior oblique and fibers of Tenon's capsule also take part. This fibrous tendon sheath is lined by a synovial layer. The width of the superior oblique muscle tendon sheath measures 2.91 +/- 0.07 mm and that of the tendon of superior oblique muscle in the sheath measures 1.35 +/- 0.23 mm, less than 1/2 of the tendon sheath, indicating the presence of a space between the two structures to facilitate movement of the tendon. The length, breadth, and the angle of reflection of the superior oblique were also measured.
在30个成人眼眶中识别出上斜肌腱鞘。该腱鞘由上睑提肌和上直肌的筋膜及其肌间隔组成。此外，上斜肌的筋膜和Tenon囊的纤维也参与其中。这个纤维性腱鞘内衬滑膜层。上斜肌腱鞘的宽度为2.91±0.07毫米，鞘内上斜肌腱的宽度为1.35±0.23毫米，不到腱鞘宽度的1/2，表明这两个结构之间存在间隙以利于肌腱运动。还测量了上斜肌的长度、宽度和反折角度。
