[Maintenance of corneal transparency].
High transparency of the cornea is necessary for good vision. The optical properties of this tissue are closely related to the underlying structure. Constant function of fluid transport systems in the endothelium and in the epithelium is required in order to maintain transparency. Presumably, this fluid transport is achieved by active transport of ions. Any disturbance of this system leads to accumulation of fluid in the cornea, which results in clouding, and thereby marked reduction of vision. Increased understanding of the basic physiology of the regulation of corneal transparency will be a help in developing diagnostic and therapeutic interventions.
