Episclera

Overview
The episclera is the outermost layer of the sclera. It is composed of loose, fibrous, elastic tissue and attaches to Tenon's capsule.

In episcleritis, the episclera and Tenon's capsule are infiltrated with inflammatory cells.

The episclera is a Vascular plexus that lies between the conjunctiva and the sclera and consists of two layers of vessels: the superficial episcleral vessels and the deep episcleral vessels.
