Paper Abstract

In this study, a diversity of the human lacrimal canaliculus (LC) shape was shown using dynamic optical coherence tomography (D-OCT) method. D-OCT is a method of clear imaging of a fluid using a contrast agent. LC plays an important role in tear drainage system and it is expected to assess LC in detail without pain of subjects. Non-invasive and non-contact OCT imaging of LC of 6 eyes of 3 subjects was performed. The LC images were cut out by applying the D-OCT method and three-dimensionally reconstructed to evaluate the characteristics of LC. Although no significant difference was found between the left and right LCs of the same subject, it was shown that individual differences were remarkable.
