The<unk> , also known as the<unk> ea or<unk>  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<unk>  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<unk>  provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the<unk>  forms the uveal tract. The structure of the<unk>  is generally divided into four layers (classified in order of furthest away from the retina to closest): *Haller's layer - outermost layer of the<unk>  consisting of larger diameter blood vessels; *Sattler's layer - layer of medium diameter blood vessels; *Choriocapillaris - layer of capillaries; and *Bruch's membrane (synonyms: Lamina basalis, Complexus basalis, Lamina vitra) - innermost layer of the<unk> .
