The term periorbita, also referred to as the orbital periosteum, is a thin, fibrous membrane that covers the surface of the eye socket. The periorbita serves to protect the orbital contents, including the eye, nerves, and muscles, from external damage. There are several other synonyms for the word periorbita, including the orbital fascia, the pericranium, and the periorbital membrane. Furthermore, the periorbita has three distinct layers, including the outer periosteal layer, the middle fibrous layer, and the inner meningeal layer. Each of these layers has its own unique function, playing a crucial role in the protection and support of the eye.
