Abstract
Optical coherence tomography (OCT) is a noninvasive, noncontact imaging instrument capable of generating high-resolution optical cross sections of the retina. Many retinal disorders have been extensively described and their pathogenesis studied by using OCT.1,2 Its particular ability to detect with high accuracy the inner and outer retinal boundaries from the acquired scans and to measure their distance (ie, retinal thickness) has made OCT increasingly popular in the quantitative assessment of macular edema.3,4 Traditional methods for assessing retinal thickening, ie, slitlamp biomicroscopy and stereoscopic photography, are qualitative and subjective and may not detect subtle macular thickening. Therefore, methods providing quantitative measurements of retinal thickening are needed.
