The Short Posterior Ciliary Arteries are small blood vessels that branch off from the ophthalmic artery, which is a major artery supplying the eye. These arteries primarily supply blood to the posterior part of the eye, including the choroid and the optic nerve. They play a crucial role in maintaining the health and function of these structures. There are typically 10 to 20 short posterior ciliary arteries, and they form a network around the optic nerve. Their proper functioning is essential for providing oxygen and nutrients to the eye, and any disruption can lead to conditions affecting vision, such as ischemia or optic neuropathy.
