What Is the Choroid of the Eye? - Verywell Health

WebThe choroid is a thin, pigmented vascular network consisting of three layers (from inner to outer): choriocapillaris, stroma, and lamina fusca. The choriocapillaris provides nutrients to the RPE and the outer third of the retina. The choroid, also known as the choroidea or choroid coat, is a part of the uvea, the vascular layer of the eye, and contains connective tissues, and lies between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm. The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms the uveal tract. reaching equilibrium biology https://caraibesmarket.com
