      Application of a Deep Machine Learning Model for Automatic Measurement of EZ Width in SD-OCT Images of RP
      Purpose : We applied a deep convolutional neural network model for automatic identification of ellipsoid zone (EZ) in spectral domain optical coherence tomography B-scans of retinitis pigmentosa (RP). Methods : Midline B-scans having visible EZ from 220 patients with RP and 20 normal subjects were manually segmented for inner limiting membrane, inner nuclear layer, EZ, retinal pigment epithelium, and Bruch's membrane. A total of 2.87 million labeled image patches (33 ...

      ackground : To evaluate diurnal variations in macular schisis cavities in patients with X-linked juvenile retinoschisis (XLRS) with pathogenic variants in the RS1 gene using spectral-domain optical coherence tomography (SD-OCT). Methods : Three consecutive patients with a clinical diagnosis of XLRS and pathogenic variants in the RS1 , treated with carbonic anhydrase inhibitors (CAIs). Observational procedures : SD-OCT scans of the macula were acquired at 9 a.m., 1 p.m., and 4 p ...

      Quantification of Ellipsoid Zone Changes in Retinitis Pigmentosa Using en Face Spectral Domain–Optical Coherence Tomography
      Importance New methods are needed to quantify the change in the outer retinal structures in retinitis pigmentosa (RP). Objective To implement an alternate method for tracking ellipsoid zone (EZ) changes in RP by quantifying the EZ area on en face spectral domainoptical coherence tomographic (SD-OCT) images. Design, Setting, and Participants Data for this observational case study were collected at the Department of Ophthalmology, University of California, Los Angeles, from May ...

      A Comparison of Methods for Tracking Progression in X-Linked Retinitis Pigmentosa Using Frequency Domain OCT
      PURPOSE: To compare the efficacy of frequency domain optical coherence tomography (fdOCT)-derived outer retinal measures in tracking disease progression in x-linked (xl) retinitis pigmentosa (RP) patients. METHODS: Macular volume scans and line scans (Spectralis) were obtained from 27 xlRP patients (15.3 6.4 years) at two visits approximately 2 years apart. Changes in average outer retinal layer thicknesses across the volume scan were compared to changes detected by ...

      Spectral-Domain Optical Coherence Tomography Measures of Outer Segment Layer Progression in Patients With X-Linked Retinitis Pigmentosa
      Importance Determining the annual rate of change in the width of the inner segment ellipsoid zone (EZ; ie, inner/outer segment border) in the context of short-term variability should allow us to better understand the value of this measure for future treatment trials in X-linked retinitis pigmentosa (XLRP). Objectives To identify the width of the central region showing an EZ and to determine the short-term repeat variability and the annual ...

      Purpose: The purpose of this study was to evaluate macular atrophy by frequency-domain optical coherence tomography (OCT) in patients with birdshot retinochoroidopathy and to compare the resulting thickness measures with visual acuity and multifocal electroretinography (mfERG). Methods: Measures were obtained from 14 eyes of 7 patients with birdshot retinochoroidopathy and 23 normal eyes. Optical coherence tomography-3 measures of macular thinning were related to visual acuity, mfERG response density, and time ...
