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 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.

This sleeve gives off an expansion called the medial check ligament that connects the medial rectus muscle with the medial wall of orbit.

External to the sclera, the eyeball is enveloped by a thin fascial sheath (so-called Tenon's capsule) that extends from the optic nerve to the sclerocorneal junction (fig. 46-3). The sheath separates the globe from the orbital fat and acts as a socket in which the eye moves as in a ball-and-socket joint. It blends with the sheaths of the.

Eyeball Structure and function Kenhub
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. 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.
These dissections serve to identify structures extrinsic to the eyeball, including extraocular muscle attachments, small vessels, optic nerve stalk, and fascial sheath of the eyeball (Tenon's fascia).

Fascial sheath of eyeball (Tenon) : Orbital cavity Extraocular muscles; Extrinsic muscles of eyeball Lacrimal apparatus : Orbital septum Eyeball/Eye : General Anatomy Lens (Eye) : Histology Iris : Anterior view Iridocorneal angle : Gonioscopy Corona ciliaris : Posterior view Retina : Histology 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.
