      Explore Nature Publishing Group Ophthalmology
      Quantification of Retinal Nerve Fibre Layer Thickness on Optical Coherence Tomography with a Deep Learning Segmentation-Free Approach
      This study describes a segmentation-free deep learning (DL) algorithm for measuring retinal nerve fibre layer (RNFL) thickness on spectral-domain optical coherence tomography (SDOCT). The study included 25,285 B-scans from 1,338 eyes of 706 subjects. Training was done to predict RNFL thickness from raw unsegmented scans using conventional RNFL thickness measurements from good quality images as targets, forcing the DL algorithm to learn its own representation of RNFL. The ...

      Reflections on the Utility of the Retina as a Biomarker for Alzheimer’s Disease: A Literature Review
      As a part of the central nervous system, the retina may reflect both physiologic processes and abnormalities related to diseases of the brain. Indeed, a concerted effort has been put forth to understand how Alzheimers disease (AD) pathology may manifest in the retina as a means to assess the state of the AD brain. The development and refinement of ophthalmologic techniques for studying the retina in vivo have produced evidence ...

      Coextensive synchronized SLO-OCT with adaptive optics for human retinal imaging
      We describe the details of a multimodal retinal imaging system which combines adaptive optics (AO) with an integrated scanning light ophthalmoscopy (SLO) and optical coherence tomography (OCT) imaging system. The OCT subsystem consisted of a swept-source, Fourier-domain mode-locked (FDML) laser, with a very high A-scan rate (1.6 MHz), whose beam was raster scanned on the retina by two scannersone resonant scanner and one galvanometer. The high sweep rate of ...

      Optical Coherence Tomography Angiography and Glaucoma: A Brief Review
      Optical coherence tomography angiography (OCTA) is a new modality in ocular imaging which provides non-invasive assessment and measurement of the vascular structures in the retina and optic nerve head. This technique provides useful information in glaucoma, such as quantitative assessment of vessel density. Vessel density measurement can be affected by various subject-related, eye-related, and diseaserelated factors. Overall, OCTA has good repeatability and reproducibility, and can differentiate glaucoma eyes from normal ...

      En face optical coherence tomography imaging of beta and gamma parapapillary atrophy in high myopia
      Objective Recent studies have suggested that optical coherence tomography (OCT)-based classification of parapapillary atrophy (PPA) may be helpful in distinguishing glaucomatous from myopic optic disc changes. However, the pathological implications of PPA may be different in highly myopic eyes that exhibit optic disc deformations distinct from low to moderate myopia. Therefore, we conducted the current study to investigate factors associated with OCT-defined PPA zones measured in en face reconstructed ...
