The firm, opaque, white, outer connective tissue layer of the posterior five-sixths of the eye is the sclera. The cornea is the transparent outer layer of the anterior portion of the eye. The vascular tunic (also known as the uvea) consists of the iris, ciliary body, and choroid. The choroid is a layer within the vascular tunic that is highly vascularized and pigmented. The nervous tunic (also known as the retina) is the innermost layer of the eye that contains photoreceptor cells and is responsible for processing visual information.
