Abstract

We report a system capable of collecting pairs of en-face OCT and confocal images from the anterior chamber. Pairs of such images are collected from up to 7 mm deep in the anterior chamber measured from the top of the cornea. The wavelength is 0.85 μm and the power 0.3 mW. The system offers: (i) versatility, being capable of displaying both C-scan OCT images (constant depth, oriented perpendicularly on the optic axis) as well as B-scan OCT images (containing the optic axis or longitudinal); (ii) eye alignment using the Purkinje reflections in the confocal channel; (iii) overall eye guidance, on the confocal image; (iv) correction for the en-face movement in the B-scan images generated by en-face imaging using the confocal image. Animations of such pairs of images demonstrate the utility of the system for in vivo imaging of the anterior segment of the eye.
