The wall of the eye is made up of three layers. The outermost layer is called the sclera; the innermost layer is the retina. The retina is further divided into an outer layer of pigmented epithelium and an inner layer of neural tissue. When the inner neural tissue separates from the outer pigmented epithelium, this abnormal condition is called retinal detachment. There are three types of retinal detachment, depending on the mechanism:
