The inserting muscle fibers pierce the fascial sheath of the eyeball (Tenon's capsule), which in turn reflects back and creates a thin fascial sleeve around the muscle's tendon. This sleeve gives off an expansion called the medial check ligament that connects the medial rectus muscle with the medial wall of orbit.

Eyeball Structure and function Kenhub
The eyeball and all of the extraocular muscles are enveloped by a muscular fascia, derived from the fascial sheath of the eyeball (Tenon's capsule). This is an important clinical point due to the fact that the subtendinous space is a common location for the injection of local anesthetics during various surgical procedures in this region.

The fascial sheath of the eyeball—also called the Tenon capsule—is a fibroelastic layer that surrounds the entire scleral portion of the globe. It delimits the episcleral space or sub-Tenon space, a potential space with no actual volume, although fluid can be injected into it. Some experts assimilate it into the articular capsule of the globe.

Tenon's capsule ( / təˈnoʊn / ), also known as the Tenon capsule, fascial sheath of the eyeball ( Latin: vagina bulbi) or the fascia bulbi, is a thin membrane which envelops the eyeball from the optic nerve to the corneal limbus, separating it from the orbital fat and forming a socket in which it moves.

The deep cervical fascia of the neck, the epicranial aponeurosis of the head, and the fascial sheath of eyeball, form the proximal PMC. Although the literature has reported an anatomical myofascial continuum between the neck, head, and eyes, the anatomical descriptions vary substantially.

The eyes are responsible for detecting visible light, which ranges from 400 to 700 nanometers in wavelength. Objects can absorb and reflect different wavelengths of light. An object appears white if it reflects all wavelengths of light, and it appears black if it absorbs all wavelengths of light.

The fascial sheath of eyeball (Tenon's capsule; Fascia bulbi) is a thin membrane which envelops the bulb of the eye from the optic nerve to the ciliary region, separating it from the orbital fat and forming a socket in which it plays. Its inner surface is smooth, and is separated from the outer surface of the sclera by the periscleral lymph space.

Tenon's capsule is a fascial sheath that encloses the eye, separating the sclera from the conjunctiva anteriorly and the orbital fat posteriorly. There is a potential space between Tenon's layer and the underlying sclera, although the two are firmly adherent to each other approximately 1.5 mm behind the limbus (the junction between sclera and cornea) and at the entry site of the optic.
