Abstract

(1) Basics and principles of optical coherence tomography (OCT), which briefly discuss the mechanisms and operation of OCT systems and a comparison of old and new systems (time domain vs. spectral domain) and their reproducibility. It concisely explains the frequency domain OCT, multiple reference OCT and hand held. (2) Normal OCT, which describes normal findings and variations that are expected on normal OCT images, and the layers of the normal retina and in different parts of the posterior segment. (3) Anterior segment OCT, which describe the mechanism and clinical applications in various disease (4) Enhanced-depth imaging (EDI)-OCT and its applications and indications in various diseases such as choroidal tumors, age-related macular degeneration, diabetic retinopathy, central serous chorioretinopathy, glaucoma, intraocular inflammation, and myopia. Moreover, choroidal measurement and its variations under different conditions are discussed. (5) OCT angiography, which explains the mechanism and Clinical application and limitations of OCTA (6) Limitations and indications of OCT, which evaluate and explain the drawbacks and advantages of this diagnostic method for the exploration of ocular pathologies. (7) Pitfalls and artifacts, which covers and illustrates diagnostic pitfalls and artifacts in OCT image interpretation in circumstances such as the presence of an epiretinal membrane and myopia (8) Artificial intelligence in OCT image analysis, which describes the classification and image synthesis and enhancement. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
