    6. Hybrid Deep Learning on Single Wide-field Optical Coherence Tomography Scans Accurately Classifies Glaucoma Suspects

      Hybrid Deep Learning on Single Wide-field Optical Coherence Tomography Scans Accurately Classifies Glaucoma Suspects
      Purpose: Existing summary statistics based upon optical coherence tomographic (OCT) scans and/or visual fields (VFs) are suboptimal for distinguishing between healthy and glaucomatous eyes in the clinic. This study evaluates the extent to which a hybrid deep learning method (HDLM), combined with a single wide-field OCT protocol, can distinguish eyes previously classified as either healthy suspects or mild glaucoma. Methods: In total, 102 eyes from 102 patients, with or ...

      Imaging Congenital Optic Disc Pits and Associated Maculopathy Using Optical Coherence Tomography
      Objective: To elucidate the anatomy of congenital optic disc pits with and without maculopathy using optical coherence tomography. Setting: All patients were examined, photographed, and scanned at the New York Eye and Ear Infirmary. Patients: Ten eyes of eight consecutive patients with congenital optic disc pits were studied. Three eyes had associated serous macular detachment (group 1), four had evidence of resolved detachment (group 2), and three had no clinical ...

    8. Association of Glaucoma-Related, Optical Coherence Tomography–Measured Macular Damage With Vision-Related Quality of Life

      Association of Glaucoma-Related, Optical Coherence Tomography–Measured Macular Damage With Vision-Related Quality of Life
      Question What is the association of structural macular retinal ganglion cell plus inner plexiform layer (RGC+IPL) loss measured by spectral-domain optical coherence tomography (SD-OCT) with vision-related quality of life among individuals with primary open-angle glaucoma? Finding In this cross-sectional study of 214 eyes of 107 patients with glaucoma, diffuse macular RGC+IPL loss, as measured by SD-OCT, was associated with diminished vision-related quality of life.

      A Novel Method for Assessing Lamina Cribrosa Structure Ex Vivo Using Anterior Segment Enhanced Depth Imaging Optical Coherence Tomography
      Purpose: The purpose of this study is to investigate the use of anterior segment enhanced depth imaging (EDI) optical coherence tomography (OCT) for ex vivo lamina cribrosa (LC) imaging. Materials and Methods: After removing anterior segment and vitreous, the optic nerve head (ONH) tissue of porcine eyes was placed on a customized eye holder for imaging. Serial EDI OCT B-scans (interval, ~35 [mu]m) of the ONH were obtained using ...
