    1. Analysis of Anterior Segment Dynamics Using Anterior Segment Optical Coherence Tomography Before and After Laser Peripheral Iridotomy

      Analysis of Anterior Segment Dynamics Using Anterior Segment Optical Coherence Tomography Before and After Laser Peripheral Iridotomy
      Objective To evaluate changes in the speed of pupil constriction and in anterior segment parameters after laser peripheral iridotomy (LPI) in patients with angle closure using anterior segment optical coherence tomography. Methods In this prospective observational study, videos of pupil and anterior segment changes in response to illumination were captured with real-time video recording using anterior segment optical coherence tomography and were analyzed frame by frame before and after LPI ...

    2. Relationship Between Intraocular Pressure and Angle Configuration: An Anterior Segment OCT Study

      Relationship Between Intraocular Pressure and Angle Configuration: An Anterior Segment OCT Study
      Purpose: To assess the relationship between intra-ocular pressure (IOP) and anterior chamber angle (ACA) configuration as assessed by gonioscopy and anterior segment optical coherence tomography (AS-OCT). Methods: 2045 subjects aged 50 years and over, recruited from a community clinic, underwent AS-OCT, Goldmann applanation tonometry, and gonioscopy. A quadrant was classified as closed on gonioscopy if the posterior trabecular meshwork could not be seen. A closed quadrant on AS-OCT was defined ...

    4. Comparison of two spectral domain optical coherence tomography devices for angle closure assessment

      Comparison of two spectral domain optical coherence tomography devices for angle closure assessment
      Purpose. To compare two spectral domain optical coherence tomography (SD-OCT) devices for the identification of angle structures and the presence of angle closure Methods. This was a prospective comparative study. Consecutive patients underwent gonioscopy and anterior segment imaging using 2 SD-OCT devices (iVue [Optovue Corporation, Fremont, Ca] and Cirrus [Carl Zeiss Meditec, Dublin, Ca]). Images were evaluated for the ability to detect angle structures such as Schwalbe's line (SL ...

    6. Evaluation of Scanning Protocols for Imaging the Anterior Chamber Angle With Anterior Segment-Optical Coherence Tomography

      Purpose: To evaluate different anterior segment-optical coherence tomography (AS-OCT) scanning protocols for detecting eyes with angle closure. Methods: This cross-sectional study enrolled 2104 subjects from a community clinic in Singapore. All participants underwent AS-OCT imaging in the dark (Visante, Carl-Zeiss, Meditec, Dublin, CA), and gonioscopy with a Goldmann 2-mirror and a Sussman lens by an experienced examiner. The anterior chamber angle in a particular quadrant was considered closed on gonioscopy ...
