Are there blood vessels in the cornea?
no
Yes, the cornea has a dense network of blood vessels called the limbal vascular plexus that surrounds its periphery, but it has no blood vessels in its central portion, which makes it one of the few tissues in the human body that is avascular (lacks blood vessels). The absence of blood vessels in the cornea is essential for maintaining its transparency and optical clarity, as blood vessels can scatter and absorb light, leading to visual impairment. Instead of blood vessels, the cornea gets its oxygen and nutrient supply from the tears and aqueous humor that bathe its surface and from the blood vessels present in the conjunctiva and ciliary body surrounding it.
