Optical coherence tomography in macular diseases

Optical coherence tomography (OCT) is a noninvasive, transpupillary imaging technology that can examine tissues with high axial and transverse resolution (in µm) in vivo. It is widely used in ophthalmology to document optic disc, nerve fibre layer and macula at different levels in front of, within and under the retina up to 2 mm in depth due to light absorption. Management of macular diseases becomes more important now-a-days due to increasing amount of patients, improved diagnostic methods and new therapeutic options. The aim of the study is to determine the role of OCT among the different examination methods on four patient groups of specific macular diseases: idiopathic macular hole, age- related macular degeneration, melanocytic choroidal tumors and circumscribed choroidal hemangioma. I have followed-up 76 patients at the Eye department of Faculty hospital Kralovske Vinohrady, Prague from January 2002 to September 2008. I have performed complete eye examination together with OCT (STRATUS OCT 3, Zeiss) on both eyes (n = 152) at all visits. "Radial lines" technique consisted of a spoke pattern protocol with 6 mm of scan length. The algorithm computed retinal map including foveal retinal thickness (FRT) and macular volume. NCSS software was used for statistics. There was reported in the group of...
