Introduction . Advances in optical coherence tomography (OCT) technology have led to the development of devices that use different algorithms. Spectral-domain OCT (SD-OCT) provides faster imaging, higher-resolution images, and an improved signal-to-noise ratio that allows us to distinguish between different layers of the retina1. Swept-source OCT (SS-OCT) increases the acquisition rate of conventional SD-OCT from 20,000 to 40,000 A-scans per second to 100,000–400,000 A-scans per se...
