Paper Abstract

We investigate the influence of the OCT system resolution on high-quality en face corneal endothelial cell images in vivo, to allow for quantitative analysis of cell density. We vary the lateral resolution of the ultrahigh-resolution (UHR) OCT system (centered at 850 nm) by using different objectives, and the axial resolution by windowing the source spectrum. We are able to obtain a high-quality en face corneal endothelial cell map in vivo using UHR OCT for the first time. Quantitative analysis result of cell density from in vivo en face corneal endothelial cell map agrees with previously reported data.
