Purpose To determine whether combining measures of retinal structure and function predicts need for intervention for diabetic retinopathy (DR) better than either modality alone. Methods The study sample consisted of 279 diabetic patients who particip

Purpose To compare the effect of variable pupil size on the flicker electroretinogram (ERG) between a stimulus having constant luminance and a stimulus having constant retinal illuminance (constant Troland) that compensates for pupil size. Methods Su

A system for measuring nanometer motions of microscopic structures is demonstrated. Stop-action images of a target are obtained with a light microscope, CCD camera, and stroboscopic illuminator. Mo- tions are determined directly from measured images

Image registration algorithms based on piecewise linear inter- polators (spatiotemporal gradients or block matching) are analyzed to determine subpixel registration accuracy. Results reveal not only random errors due to image noise but also systemati
