Choroid

 

The choroid is the layer of blood vessels and connective tissue between the white of the eye and retina (at the back of the eye). It is part of the uvea and supplies nutrients to the inner parts of the eye. Inflammation of the choroid is called choroiditis.

    Eye - illustration

    The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.
