Carbohydrates of the Lens in Normal and Precataractous States.

The free carbohydrates of the lens are discussed, with particular attention to the normal concentrations. Simple sugar derivatives such as the sugar alcohols are similarly treated. Such metabolic intermediates as the sugar phosphates and the more complex adenosine derivatives are mentioned, as are structural components containing sugar moieties. Experimental procedures, such as special diets, ivhich alter lens sugar levels are briefly outlined.
