Abstract
A method for detecting the presence of diabetes mellitus and for monitoring eye lens changes resulting from the disease is disclosed. The method involves ascertaining the diffusion coefficient of the lens of a patient's eye by directing a light beam from a low-power laser at a clear site in the lens of an in vivo eye and measuring the intensity of the back-scattered light. It has been found that the diffusion coefficient decreases more rapidly versus age in patients suffering from diabetes mellitus than for nondiabetic patients. Thus by comparing the intensity of back scattered light with the patient's age the presence of diabetes, the amount of damage caused by the disease and the efficacy of treatment can be detected.
