Central retinal artery
Central Retinal Artery
The Central Retinal Artery (CRA) is a branch of the Ophthalmic Artery that supplies blood to the inner two-thirds of the Retina. It is a crucial component of the Eye Anatomy and plays a significant role in maintaining the health and function of the retina.
Anatomy[edit | edit source]
The central retinal artery enters the optic nerve approximately 1 cm behind the globe (eye ball) and runs within the nerve to supply the retina. It is the first branch of the ophthalmic artery and is a terminal artery without any anastomotic connections.
Clinical Significance[edit | edit source]
Blockage of the central retinal artery (Central Retinal Artery Occlusion) can lead to sudden, painless, and usually severe loss of vision in one eye. This is considered a medical emergency.
