In this study, the human lacrimal canaliculus (LC), an important segment of the lacrimal drainage system, was imaged using dynamic optical coherence tomography (D-OCT) and the 3D structure of the LC was rendered. In D-OCT system, a turbid commercial

Recently, in vivo trans-conjunctiva optical coherence tomography (OCT) imaging of the lacrimal passage was demonstrated using a turbid commercial eye drop as an extrinsic contrast agent. However, static OCT images are not sufficient to unambiguously

Background Optical coherence tomography (OCT) has become a promising diagnostic tool in many medical fields. In particular, noninvasive real-time optical biopsy of internal organs is one of the most attractive applications of OCT, enabling in situ di
