The episclera is another name for which connective tissue fascia?

The surrounding tissue concept is about how the eye is wrapped in connective layers. The episclera is a thin, vascular connective tissue layer that lies on the outer surface of the sclera, and it forms part of the fascial system that encloses the eyeball. This fascial sheath is Tenon's fascia (Tenon’s capsule), so the episclera is effectively another name used for that same connective tissue envelope around the globe. The other structures are not the enclosing fascia: the uvea is the vascular middle layer inside the eye; the stroma refers to supportive tissue within a specific structure like the cornea; and the canal of Schlemm is a drainage channel in the eye’s drainage system.
