The cornea is the transparent outer layer of the eye. Corneal tissue consists of five layers: the epithelium, the Bowman’s layer, the stroma, the Descemet’s membrane, and the endothelium. A corneal dystrophy is a condition in which one or more parts of the cornea lose their normal clarity due to the accumulation of abnormal material. Corneal dystrophies generally affect both eyes.
Any of several inherited disorders in which the cornea becomes cloudy, hazy, or speckled, resulting in variable degrees of visual loss.
