title: [Tendon sheath of the superior oblique muscle and its measurements].
abstract: 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.
