Optical coherence tomography (OCT) is a new, noninvasive, high resolution, cross-sectional imaging technology. OCT is useful for both quantitative and qualitative analysis of retinal disease and glaucoma. In retinal disease, OCT can be used in the diagnosis and monitoring of macular holes, macular edema, age-related macular degeneration, and other retinal pathologies. OCT also can be used in glaucoma diagnostics, providing objective, quantitative measurement of nerve fiber layer thickness.
