ABSTRACT
Objective To present a new imaging method for the anterior segment of the eye.
Methods Transscleral optical coherence tomographic images were generated in
healthy volunteers using a slitlamp-adapted prototype equipped with a superluminescence
diode with an infrared wavelength of 1310 nm.
Results The optical coherence tomographic system used allowed penetration of
human sclera in vivo and high-resolution, cross-sectional imaging of the anterior
chamber angle and the ciliary body.
Conclusion The 1310-nm optical coherence tomographic image shows a significant
potential as a noninvasive diagnostic tool for the anterior segment of the
eye.
