Limitations of Fourier-domain OCT

摘要

At the time of writing this letter, the RTVue-100 (Optovue, Inc.) used by Wylegala et al. is the only commercially available Fourier-domain optical coherence tomography (OCT) device that can scan the anterior segment without "personal" modifications. Similar to all commercially available Fourier-domain OCT devices, it uses shorter wavelength light than the Visante-OCT (Carl Zeiss Meditec) (840 nm versus 1310 run). It scans at a faster rate (26 000 A-scans/s) than time-domain OCT devices (2048 A-scans/s for Visante-OCT). This improves image quality by achieving higher resolution and also reducing motion artifact.
