    2. Optical Coherence Tomography in High Myopia

      Optical Coherence Tomography in High Myopia
      Optical coherence tomography (OCT) is a precise technology that can be used for interrogating tissue structure and function noninvasively, painlessly, and quickly using near-infrared light. At its inception, OCT was typically a tool for assessing tissue thickness. Time-domain OCT is fast enough to scan a circle centered on the optic nerve head (circumpapillary) to assess retinal nerve fiber layer (RNFL) thickness. With the development of spectral-domain OCT, volumetric (3-dimensional) scanning ...

      Clinical Utility of Optical Coherence Tomography in Glaucoma
      Optical coherence tomography (OCT) has established itself as the dominant imaging modality in the management of glaucoma and retinal diseases, providing high-resolution visualization of ocular microstructures and objective quantification of tissue thickness and change. This article reviews the history of OCT imaging with a specific focus on glaucoma. We examine the clinical utility of OCT with respect to diagnosis and progression monitoring, with additional emphasis on advances in OCT technology ...

    5. Optic Nerve Head Measurements With Optical Coherence Tomography: A Phantom-Based Study Reveals Differences Among Clinical Devices

      Optic Nerve Head Measurements With Optical Coherence Tomography: A Phantom-Based Study Reveals Differences Among Clinical Devices
      Purpose : Optical coherence tomography (OCT) can monitor for glaucoma by measuring dimensions of the optic nerve head (ONH) cup and disc. Multiple clinical studies have shown that different OCT devices yield different estimates of retinal dimensions. We developed phantoms mimicking ONH morphology as a new way to compare ONH measurements from different clinical OCT devices. Methods : Three phantoms were fabricated to model the ONH: One normal and two with glaucomatous ...

    6. The APOSTEL recommendations for reporting quantitative optical coherence tomography studies

      The APOSTEL recommendations for reporting quantitative optical coherence tomography studies
      Objective: To develop consensus recommendations for reporting of quantitative optical coherence tomography (OCT) study results. Methods: A panel of experienced OCT researchers (including 11 neurologists, 2 ophthalmologists, and 2 neuroscientists) discussed requirements for performing and reporting quantitative analyses of retinal morphology and developed a list of initial recommendations based on experience and previous studies. The list of recommendations was subsequently revised during several meetings of the coordinating group. Results: We ...

    10. Virtual Averaging Making Nonframe-Averaged Optical Coherence Tomography Images Comparable to Frame-Averaged Images

      Virtual Averaging Making Nonframe-Averaged Optical Coherence Tomography Images Comparable to Frame-Averaged Images
      Purpose : Developing a novel image enhancement method so that nonframe-averaged optical coherence tomography (OCT) images become comparable to active eye-tracking frame-averaged OCT images. Methods : Twenty-one eyes of 21 healthy volunteers were scanned with noneye-tracking nonframe-averaged OCT device and active eye-tracking frame-averaged OCT device. Virtual averaging was applied to nonframe-averaged images with voxel resampling and adding amplitude deviation with 15-time repetitions. Signal-to-noise (SNR), contrast-to-noise ratios (CNR), and the distance between the ...

    15. In Vivo Evaluation of White Matter Integrity and Anterograde Transport in Visual System After Excitotoxic Retinal Injury With Multimodal MRI and OCT

      In Vivo Evaluation of White Matter Integrity and Anterograde Transport in Visual System After Excitotoxic Retinal Injury With Multimodal MRI and OCT
      Purpose. Excitotoxicity has been linked to the pathogenesis of ocular diseases and injuries and may involve early degeneration of both anterior and posterior visual pathways. However, their spatiotemporal relationships remain unclear. We hypothesized that the effects of excitotoxic retinal injury (ERI) on the visual system can be revealed in vivo by diffusion tensor magnetic resonance imagining (DTI), manganese-enhanced magnetic resonance imagining (MRI), and optical coherence tomography (OCT). Methods. Diffusion tensor ...

  3. Quotes

    1. OCT will be able to detect glaucomatous abnormalities prior to our current functional measurement technology being able to detect them, and the earlier in the disease that you can detect damage or progression, the more likely it is you are able to prevent further progression with less intensive intervention.
      In Emerging technologies open new horizons in glaucoma structural evaluation, management
    2. I’m delighted by the Champalimaud Foundation’s recognition of our efforts...We continue to work on improving OCT and in the next decade, it could be as portable and easy to use as a standard ophthalmoscope.
      In Joel S. Schuman, M.D., Part of Team Receiving António Champalimaud Vision Award
    3. That gives the promise to better track progression to detect change over time, and that is really a big advance in terms of changes from time-domain OCT.
      In OCT devices increasingly finding use outside retinal practice
    4. You can look for characteristic nerve fiber layer abnormalities that are seen in glaucoma and these will show up as arcuate abnormalities — deviations from normal — on the deviation map of the spectral-domain OCT.
      In OCT devices increasingly finding use outside retinal practice
    5. With imaging we have much younger technology. The progression assessments with these technologies seem to be more sensitive than functional assessment, but they don't necessarily overlap with functional assessment or even with each other.
      In Better Glaucoma Progression Tracking
    6. I think that in future iterations we will be able to have focal assessment of change, looking at the overall trend as in regression, but also looking at event analysis, analogous to the GPA on visual field.
