Abstract
We use the prototype swept-source (SS) OCT at 1060 nm to image human Schlemm’s canal (SC) and perform full reconstruction in the en face plane. Compared with spectral-domain (SD) OCT systems at 800 nm, the SS OCT system at 1060 nm offers deeper signal penetration, and has no sensitivity roll-off effect to allow for better localization and delineation of SC. One volumetric scan was taken from each of the eight cardinal positions to cover the entire SC circumferentially around the limbus. The en face slices were taken from each volume at the SC region, and were stitched together to generate an en face representation of the 360 deg SC.
