Image Processing and Analysis to Diagnose Ocular Refraction Errors

We describe ongoing research into the development of a functional system for diagnosing and measuring ocular refractive errors in the human eye (astigmatism, hypermetropia and myopia) by automatically analyzing images of the human ocular globe acquired with the Hartmann-Shack (H-S) technique. H-S images are to be input into a system capable of recognizing the presence of a refractive error and outputting a measurement of such an error. Because the H-S technique provides images rich with information on the human eye, we believe this system may provide a framework that can be extended to obtain additional information on the health of imaged ocular globes.
