idiopathic bilateral severe corneal edema. The cause is still being investigated. Some of the characteristic features of corneal epithelial edema – hydropic intra- and extracellular changes and intercellular vesicles – increase the quantity and intensity of echo interfaces and result in the appearance of a thicker, more reflective epithelium and Bowman’s layer. An increase in the thickness and the reflectivity of the stroma also occurs with the increased spacing of corneal lamellae and appearanc
