Optical Coherence Tomography – Spectral Domain and Swept Source –

Abstract

Optical coherence tomography (OCT), initially introduced to Japan in 1997, has been able to visualize each retinal layer clearly using the commercialized Spectral Domain (SD) OCT. The newest device Swept Source (SS) OCT with 1050 nm light source and SD-OCT with some techniques currently can provide the beautiful images of the outer retinal layers including photoreceptors, vitreous, choroid, and even sclera in the posterior pole. These OCT images have been helpful to understand the pathophysiology of the various retinal, especially macular diseases. This literature might give the explanation of the example OCT images and the idea.
