Episclera

The episclera is a part of the choroid of the eye, which is located in the posterior part of the eyeball, between the sclera and the retina. It consists of thin connective tissue imbued with blood and lymphatic vessels, as well as glands.

The episcleral space serves to attach the vessels, muscles and other structures of the eye to the underlying membrane. It is also of great importance for the innervation and blood circulation of the retina. The episclera is quite thin, but has high strength due to collagen and other proteins.

When the eyes are exposed to various strains or stress, such as prolonged visual stress, prolonged practice with increased levels of contrast, eye trauma or occupational activity, structural changes in the episclera may develop. This can cause damage to blood vessels and nerves, which may manifest as pain, inflammation, swelling, hemorrhage or decreased visual acuity
