Noninvasive, cross-sectional imaging with quantitative information make Optical Coherence Tomography (OCT) an important technique for diagnosis. These advantageous features help to understand the pathogenesis of the disease and to monitor the treatment. This article focuses on the specific features of the tomograms which are useful in the diagnostic evaluation of macular diseases. OCT is an important noninvasive technique with wide applications.
It is a cheap, safe and non-invasive technique which give high-resolution cross-sectional images for the diagnostic purpose. The difference in the contrast in optical reflectivity of tissue microstructures makes the basis of OCT imaging. It allows simultaneous viewing of the positions on the ocular structure as well as its cross-sectional image. These images also contain quantitative information on dimensions of intraocular structures with…
