    2. Examination of Gland Dropout Detected on Infrared Meibography by Using Optical Coherence Tomography Meibography

      Examination of Gland Dropout Detected on Infrared Meibography by Using Optical Coherence Tomography Meibography
      Purpose To elucidate the anatomic details of gland dropout detected on two-dimensional infrared (IR) meibography in cases of dry eye associated with meibomian gland dysfunction (MGD) by using three-dimensional optical coherence tomography (OCT) meibography. Methods In this cross-sectional, observational case series, we enrolled gland dropout detected on IR meibography; the condition was then examined using a real-time swept-source OCT system. Accordingly, a series of 500 raster B-scan OCT images, with ...

    3. Epithelium and Bowman’s layer thickness and light scatter in keratoconic cornea evaluated using ultrahigh resolution optical coherence tomography

      Epithelium and Bowman’s layer thickness and light scatter in keratoconic cornea evaluated using ultrahigh resolution optical coherence tomography
      A custom-developed ultrahigh resolution optical coherence tomography with an axial resolution of 1.1 m in corneal tissue was used to characterize thickness and light scatter of the epithelium and Bowmans layer in keratoconic (KC) cornea noninvasively. A 4-mm wide vertical corneal section around the apex in nine KC and eight normal eyes was imaged in vivo . The epithelium and Bowmans layer were visualized and their thickness profiles were quantified ...

    4. A novel scanning system for imaging the entire anterior segment of the eye using an anterior segment OCT

      A novel scanning system for imaging the entire anterior segment of the eye using an anterior segment OCT
      The ability to image the entire anterior segment from anterior surface of the cornea to the posterior surface of the lens is crucial for understanding accommodation and the efficacy of accommodative intraocular lenses. A novel scanning system for an anterior segment optical coherence tomography (AS-OCT) system was designed to achieve this goal. In contrast to the traditional telecentric scanning method, this system shines OCT beams close to normal incidence on ...
