Optical Coherence Tomography—Atlas and Text

by Samuel Boyd, Rosario Brancato, Bradley Straatsma

Optical Coherence Tomography (OCT) is a contemporary diagnostic imaging technique. The available resolution with existing instrumentation at present varies around 5 to 10 microns. OCT is intended to facilitate in the assortment of which protocol to use and how to use it. The protocol groups contain Activity Radio Buttons, Glaucoma Protocols, Retina Protocols, and General Tips. OCT visualizes different layers of the retina with a great deal of precision. With the expansion of sophisticated surgical techniques, it became essential to obtain elaborate static and dynamic measurements of the anterior segment in order to meet modern safety requirements. There are various artistic interpretations of OCT to view cross section of clear corneal incisions. OCT provides various measurements that can be used in the diagnosis, evaluation, and management of glaucoma and retinal pathologies. OCT gives images of the retina and its layers. OCT is a valuable adjunct to comprehensive ophthalmic examination. Conventional OCT has some limitations that are overcome by 3D-OCT in the evaluation of retinal disease. OCT usage in diabetic retinopathy, diabetic macular edema, macular holes, cystoid macular edema, and age-related macular degeneration is discussed.
