    2. A Topographic Comparison of OCT Minimum rim Width (BMO-MRW) and Circumpapillary Retinal nerve Fiber Layer (cRNFL) Thickness Measures in Eyes with or Suspected Glaucoma

      A Topographic Comparison of OCT Minimum rim Width (BMO-MRW) and Circumpapillary Retinal nerve Fiber Layer (cRNFL) Thickness Measures in Eyes with or Suspected Glaucoma
      Prcis: Bruchs membrane opening-minimum rim width and circumpapillary retinal nerve fiber layer thickness measures may be improved by comparing probability levels and accounting for blood vessel locations. Purpose: To understand the differences between two optical coherence tomography (OCT) measures of glaucomatous damage: the Bruchs membrane opening-minimum rim width ( BMO-MRW ) and circumpapillary retinal nerve fiber layer (cRNFL) thickness. Materialsand Methods: OCT circle scans were obtained for an early glaucoma group (EG ...

    3. Improving the Detection of Glaucoma and Its Progression: A Topographical Approach

      Improving the Detection of Glaucoma and Its Progression: A Topographical Approach
      Glaucoma is typically defined as a progressive optic neuropathy characterized by a specific (arcuate) pattern of visual field (VF) and anatomical changes. Therefore, we should be comparing arcuate patterns of damage seen on VFs with those seen on optical coherence tomography ( OCT ) maps. Instead, clinicians often use summary metrics such as VF pattern standard deviation (PSD), OCT retinal nerve fiber (RNF) global thickness, etc. There are two major impediments to ...

    4. Qualitative evaluation of neuroretinal rim and retinal nerve fibre layer on optical coherence tomography to detect glaucomatous damage

      Qualitative evaluation of neuroretinal rim and retinal nerve fibre layer on optical coherence tomography to detect glaucomatous damage
      Purpose To understand the added value of Bruchs membrane opening-minimum rim width (BMO-MRW) measurements to conventional circumpapillary retinal nerve fibre layer (cpRNFL) thickness measurements on optical coherence tomography (OCT) imaging for discriminating between perimetric glaucoma and healthy eyes, evaluated through a qualitative evaluation. Methods 384 healthy eyes and 188 glaucoma eyes were evaluated, and glaucoma eyes were categorised as perimetric (n=107) based on a history of 3 consecutive abnormal ...

    6. An Examination of the Frequency of Paravascular Defects and Epiretinal Membranes in Eyes With Early Glaucoma Using En-face Slab OCT Images

      An Examination of the Frequency of Paravascular Defects and Epiretinal Membranes in Eyes With Early Glaucoma Using En-face Slab OCT Images
      Purpose: To examine the frequency of paravascular defects (PDs) and macular epiretinal membranes (ERMs) in eyes categorized as having mild glaucoma or glaucoma suspect using en-face slab analysis of optical coherence tomography (OCT) scans. Materials and Methods: Fifty-seven glaucomatous eyes, 44 low-risk suspect eyes, and 101 healthy control eyes were included in the study. The 101 glaucomatous and suspect eyes had a mean deviation better than 6dB on the 24-2 ...

      Optical coherence tomography circle scans can be used to study many eyes with advanced glaucoma
      Purpose To examine the utility of optical coherence tomography (OCT) for studying eyes with advanced glaucoma [i.e., eyes with a 24-2 visual field (VF) mean deviation (MD) worse than -15 dB], we tested the hypothesis that if these eyes had a 10-2 total deviation (TD) map with points better than -8 dB, then the topographically corresponding regions on the circumpapillary retinal nerve fiber layer (cpRNFL) should show a preserved ...

    8. Comparison of Widefield and Circumpapillary Circle Scans for Detecting Glaucomatous Neuroretinal Thinning on Optical Coherence Tomography

      Comparison of Widefield and Circumpapillary Circle Scans for Detecting Glaucomatous Neuroretinal Thinning on Optical Coherence Tomography
      Purpose : Our purpose was to compare the effectiveness of detecting progressive retinal nerve fiber layer (RNFL) thickness changes using widefield scans compared to circumpapillary circle scans derived from optic disc volume scans when using a manual region-of-interest (ROI) approach . Methods : In a prospective observational study, a total of 125 eyes diagnosed clinically with glaucoma or suspected glaucoma that had both widefield (12 9 mm) and optic disc (6 6 mm ...

      Evaluation of a Qualitative Approach for Detecting Glaucomatous Progression Using Wide-Field Optical Coherence Tomography Scans
      Purpose : To determine the effectiveness of detecting glaucomatous progression by a qualitative evaluation of wide-field (12 9 mm) scans on optical coherence tomography imaging. This method was compared to a conventional quantitative analysis of the global circumpapillary retinal nerve fiber layer (cpRNFL) thickness. Methods : A total of 409 eyes with a clinical diagnosis of glaucoma or suspected glaucoma for which two wide-field scans were obtained at least 1 year apart ...

      Evaluation of a Region-of-Interest Approach for Detecting Progressive Glaucomatous Macular Damage on Optical Coherence Tomography
      Purpose : To evaluate a manual region-of-interest (ROI) approach for detecting progressive macular ganglion cell complex (GCC) changes on optical coherence tomography (OCT) imaging. Methods : One hundred forty-six eyes with a clinical diagnosis of glaucoma or suspected glaucoma with macular OCT scans obtained at least 1 year apart were evaluated. Changes in the GCC thickness were identified using a manual ROI approach (ROI M ), whereby region(s) of observed or suspected ...

      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 ...

Methods : Wide-field ssOCT cube scans were obtained from 16 patients (16 eyes). Averaged B-scans and SW-AF images were obtained using Spectralis HRA+OCT. NIR-AF images were obtained from 6 eyes.

      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.

    1. With the NSTIN plot, the temporal quadrant of the retinal nerve fiber layer is displayed in the center of the B-scan. This portion of the disc is crucial for everyday visual function, and identification of abnormal thinning in this region is essential for managing glaucoma.
