Tissue Discrimination Imaging of Anterior Eye

Our colleague Arata Miyazawa reported a new imaging methodology which used polarization sensitive optical coherence tomography (PS-OCT) and a newly developed algorithm to discriminate tissues based on their optical properties. This algorithm uses three optical properties obtained by PS-OCT including scattering intensity, signal extinction coefficient along depth, and local birefringence, and discriminates tissues based on these properties. By using this algorithm, five tissue types of an anterior eye including trabecular meshwork, conjunctiva, sclera, cornea and uvea were successfully discriminated. The details was published in Optics Express.
