Arteries Episcleral

Episcleral arteries (a. episclerales) are large vessels that nourish the episclera - a thin transparent membrane located under the conjunctiva and directly above the sclera of the eye. Episcleral arteries belong to the intraocular circulatory system and are branches of the oculomotor artery (a. ophthalmica).

The episcleral arteries are divided into two branches - superior (pna) and inferior (bna). The superior branch runs along the upper edge of the orbit, and the lower branch along the lower edge. Each of the branches gives off shoots that penetrate the episclera and provide it with nutrition.

Episcleral arteries are important for maintaining eye health, as they provide oxygen and nutrients to the tissues of the eyeball. They also play a role in thermoregulation of the eye, helping to maintain optimal temperature in the orbit.

Impaired blood supply to the episclera can lead to various eye diseases, such as scleritis (inflammation of the sclera), episcleritis (inflammation of the episclera) and others. Therefore, it is important to ensure proper blood supply to the eye, as well as promptly consult a doctor if any unusual symptoms appear.

In conclusion, we can say that the episcleral arteries are important elements of the intraocular circulation, which provide nutrition and thermoregulation of the episclera and the eyeball as a whole. Therefore, their health and normal functioning are of great importance for maintaining eye health.
