    2. Global optical coherence tomography measures for detecting the progression of glaucoma have fundamental flaws

      Global optical coherence tomography measures for detecting the progression of glaucoma have fundamental flaws
      Objective To understand the problems involved in using global OCT measures for detecting progression in early glaucoma. Subjects/Methods Eyes from 76 patients and 28 healthy controls (HC) had a least two OCT scans at least 1 year apart. To determine the 95% confidence intervals (CI), 151 eyes (49 HC and 102 patients) had at least two scans within 6 months. All eyes had 24-2 mean deviation -6dB. The average ...

    3. Did the OCT Show Progression Since the Last Visit?

      Did the OCT Show Progression Since the Last Visit?
      Identifying progression is of fundamental importance to the management of glaucoma. It is also a challenge. The most sophisticated, and probably the most useful, commercially available clinical tool for identifying progression is the Guided Progression Analysis (GPA), which was initially developed to identify progression using 24-2 visual field tests. More recently it has been extended to retinal nerve fiber layer (RNFL) and ganglion cell + inner plexiform layer (GCIPL) thicknesses measured ...

    4. Robust and Interpretable Convolutional Neural Networks to Detect Glaucoma in Optical Coherence Tomography Images

      Robust and Interpretable Convolutional Neural Networks to Detect Glaucoma in Optical Coherence Tomography Images
      Recent studies suggest that deep learning systems can now achieve performance on par with medical experts in diagnosis of disease. A prime example is in the field of ophthalmology, where convolutional neural networks (CNNs) have been used to detect retinal and ocular diseases. However, this type of artificial intelligence (AI) has yet to be adopted clinically due to questions regarding robustness of the algorithms to datasets collected at new clinical ...

    5. Reasons why OCT Global Circumpapillary Retinal Nerve Fiber Layer Thickness is a Poor Measure of Glaucomatous Progression

      Reasons why OCT Global Circumpapillary Retinal Nerve Fiber Layer Thickness is a Poor Measure of Glaucomatous Progression
      Purpose: To assess the effects of local defects, segmentation errors, and improper image alignment on the performance of the commonly used optical coherence tomography (OCT) measure of progression, that is the change in global (average) circumpapillary retinal nerve fiber layer (cpRNFL) thickness (G). Methods: One hundred fifty eyes suspected of, or with, early glaucoma had OCT circle and cube scans obtained using eye tracking on two occasions at least 1 ...

    6. Optical Coherence Tomography Can Be Used to Assess Glaucomatous Optic Nerve Damage in Most Eyes With High Myopia

      Optical Coherence Tomography Can Be Used to Assess Glaucomatous Optic Nerve Damage in Most Eyes With High Myopia
      Precis: It is generally assumed that optical coherence tomography ( OCT ) cannot be used to diagnose glaucomatous optic neuropathy ( GON ) in high myopes. However, this study presents evidence that there is sufficient information in OCT scans to allow for accurate diagnosis of GON in most eyes with high myopia . Purpose: The purpose of this study was to test the hypothesis that glaucomatous damage can be accurately diagnosed in most high myopes ...

    7. 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 ...

    8. 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 ...

    9. 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 ...

      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 ...

      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 ...

    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.
