Which arteries primarily supply the anterior choroid?

• A. Long Posterior Ciliary Arteries (LPCAs)
• B. Short Posterior Ciliary Arteries (SPCAs)
• C. Central Retinal Arteries
• D. Anterior Ciliary Arteries

Answer: (A)

Blood supply to the choroid comes mainly from the posterior ciliary arteries, which split into short and long branches. The short posterior ciliary arteries reach the posterior choroid and outer retina, while the long posterior ciliary arteries travel forward toward the ciliary body and iris. As they move anteriorly, they give off branches that nourish the anterior choroid, making them the primary source for that region. The central retinal artery supplies the inner retina, not the choroid, and the anterior ciliary arteries mainly feed the anterior segment structures (conjunctiva, sclera near the limbus, and the ciliary body), not the choroid. So, the long posterior ciliary arteries are the major suppliers of the anterior choroid.
