    3. Polarization-multiplexed, dual-beam swept source optical coherence tomography angiography

      Polarization-multiplexed, dual-beam swept source optical coherence tomography angiography
      A polarization-multiplexed, dual-beam setup is proposed to expand the field of view for a swept source optical coherence tomography angiography (OCTA) system. This method used a Wollaston prism to split sample path light into two orthogonal-polarized beams. This allowed two beams to shine on the cornea at an angle separation of ~ 14 degrees, which led to a separation of ~ 4.2 mm on the retina. A 3-mm glass plate was ...

    5. Automated detection of photoreceptor disruption in mild diabetic retinopathy on volumetric optical coherence tomography

      Automated detection of photoreceptor disruption in mild diabetic retinopathy on volumetric optical coherence tomography
      Diabetic retinopathy is a pathology where microvascular circulation abnormalities ultimately result in photoreceptor disruption and, consequently, permanent loss of vision. Here, we developed a method that automatically detects photoreceptor disruption in mild diabetic retinopathy by mapping ellipsoid zone reflectance abnormalities from en face optical coherence tomography images. The algorithm uses a fuzzy c-means scheme with a redefined membership function to assign a defect severity level on each pixel and generate ...

    6. Optical Coherence Tomography Angiography in Neuro-Ophthalmology

      Optical Coherence Tomography Angiography in Neuro-Ophthalmology
      Optical coherence tomography (OCT) has become the most commonly performed imaging procedure in ophthalmology (1,2). Conventional OCT provides high-resolution structural information of the retina and optic nerve. More recent functional extensions such as Doppler OCT (3) and OCT angiography (OCTA) (4) have emerged as useful tools for vascular evaluation of eye diseases, including optic neuropathies. This issue of the Journal of Neuro-Ophthalmology has 2 articles (5,6) demonstrating the ...

    9. Automated drusen detection in dry age-related macular degeneration by multiple-depth, en face optical coherence tomography

      Automated drusen detection in dry age-related macular degeneration by multiple-depth, en face optical coherence tomography
      We introduce a method to automatically detect drusen in dry age-related macular degeneration (AMD) from optical coherence tomography with minimum need for layer segmentation. The method is based on the en face detection of drusen areas in C-scans at certain distances above the Bruchs membrane, circumventing the difficult task of pathologic retinal pigment epithelium segmentation. All types of drusen can be detected, including the challenging subretinal drusenoid deposits (pseudodrusen). The ...

      Projection-resolved optical coherence tomography angiography exhibiting early flow prior to clinically observed retinal angiomatous proliferation
      Purpose The purpose of this study is to analyze early retinal angiomatous proliferation (RAP) utilizing a novel imaging modality, Projection-Resolved Optical Coherence Tomography Angiography (PR-OCTA). Observations Five months prior to the diagnosis of a RAP lesion, cross-sectional PR-OCTA demonstrated flow in the outer retina contiguous with the deep retinal capillary plexus (DCP) and adjacent to a small pigment epithelial detachment. After development of a clinically visible RAP lesion, cross-sectional PR-OCTA ...
