Quantifying frequency content in cross-sectional retinal scans of diabetics vs. controls
Version 1Purpose: To examine subtle differences in the structure of diabetic vs. control retinas. Methods: Spectral-domain optical coherence tomography (SD-OCT) images were compared for the retinas of 33 diabetic subjects who did not have clinical evidence of diabetic macular edema and age-matched controls, with central macular thicknesses of 275 and 276 microns, respectively. Cross-sectional retinal images through the fovea, called B-scans, were analyzed for spatial frequency content. The B-scans were
