Optical coherence tomography: From technology to applications in ophthalmology

The relatively fast translation of optical coherence tomography (OCT) from an optical measurement technology to a standard of care in ophthalmology was driven by its ability to address clear unmet diagnostic needs. OCT's further technological developments have expanded its clinical use by extending the imaging range (wider, deeper) and the imaging contrast (from morphology to blood flow). The translation of technical advances into clinical value is an ongoing process involving both the potential substitution of established diagnostics (such as fundus angiography) and the identification of novel feature‐disease correlations. This review looks into the development, the status and the prospects of OCT with regard to translation to clinical routine in ophthalmology.
