This special issue covers the progress of imaging technologies of anterior segment of the eye, development of novel imaging devices of anterior segment, and the clinical and research application of the imaging modalities of anterior segment. In this annual issue, the authors contributed one review paper 10 research articles regarding the application of the various anterior segment imaging modalities in the diagnosis and treatment of various anterior segment diseases as well as in research of these diseases.

In this annual issue, the guest editorial team contributed a review paper regarding the following topic: application of intraoperative optical coherence tomography technology in anterior segment surgery. In this article, the authors summarized the recent development of intraoperative application of anterior segment optical coherence tomography technologies.

Authors from various countries conducted research on various imaging techniques and devices of anterior segment structures and contributed the results of their studies to this annual issue, as follows: (1) Changes of Lacrimal Puncta by Anterior Segment Optical Coherence Tomography after Topical Combined Antibiotic and Steroid Treatment in Cases of Inflammatory Punctual Stenosis; (2) Comparison of Consecutive Therapeutic Effects of Nanoemulsion and Emulsion Cyclosporin in Dry Eye Patients after Short-Term Treatment with Topical Fluorometholone; (3) The Efficacy of Clinical Tests to Diagnose Evaporative Dry Eye Disease Related to Meibomian Gland Dysfunction; (4) The Effectiveness of Laser Peripheral Iridotomy in Adolescent Eyes with Ocular Hypertension and Concave Configuration of the Peripheral Iris; (5) Evaluation of Intraocular Lens Tilt and Decentration in Congenital Ectopia Lentis by the Pentacam Scheimpflug System; (6) Specular Microscopic Corneal Endothelial Cell Changes following Uneventful Phacoemulsification in Patients with Gout; (7) Simultaneous Corneal Topography and Epithelial Thickness Mapping from a Single Measurement Using Optical Coherence Tomography; (8) Factors Related to Visual Outcomes after Lens Surgery in Isolated Microspherophakia; (9) Characteristics of Anterior Segment in Congenital Ectopia Lentis: An SS-OCT Study; (10) Characteristics of Optic Neuritis in South Korean Children and Adolescents: A Retrospective Multicenter Study.

Progress of imaging technologies of anterior segment of the eye and development of imaging devices of the anterior segment structures may allow optimal management of anterior segment diseases, such as corneal and conjunctival disorders, cataract, glaucoma, and diseases of the lacrimal system and eyelid.
