What is the term for the first branch of the ophthalmic artery supplying nutrition to the retina?

The term for the first branch of the ophthalmic artery that supplies nutrition to the retina is the Central retinal artery. This artery is crucial as it enters the eye and branches into smaller vessels that nourish the inner layers of the retina. The retina relies heavily on this blood supply for its function, as it is responsible for converting light into neural signals for the brain to interpret vision.

Other options such as the Lacrimal artery primarily supply the lacrimal gland, which is involved in tear production, and do not provide direct vascular support to the retina. Meanwhile, the Superior ophthalmic vein is a venous structure that drains blood away from the eye and surrounding tissues rather than supplying nutrients. Lastly, the Frontal artery mainly supplies structures in the forehead and scalp and does not play a role in retinal nutrition. Understanding the specific roles of these arteries helps to clarify why the Central retinal artery is the correct choice.
