Abstract

Small foveal retinal lesions are often difficult to detect with conventional ophthalmoscopy, as well as the visual functions effects of such damage. In order to improve conventional ophthalmoscopy of such lesions we have adapted computer image analysis techniques to quantify the spatial and temporal characteristics of such lesions. Our methodology incorporates conventional statistical tests of significance for plotting gray scale differences along common retinal landmarks. Preliminary data indicates that punctate retinal lesions in the fovea vary over time somewhat differently than similar size lesions placed parafoveally. Such temporal variations in gray scale distribution may aid in explanation of visual functional affects of such lesions.
