    2. Diagnosis of Choroidal Disease With Deep Learning-Based Image Enhancement and Volumetric Quantification of Optical Coherence Tomography

      Diagnosis of Choroidal Disease With Deep Learning-Based Image Enhancement and Volumetric Quantification of Optical Coherence Tomography
      Purpose: The purpose of this study was to quantify choroidal vessels (CVs) in pathological eyes in three dimensions (3D) using optical coherence tomography (OCT) and a deep-learning analysis. Methods: A single-center retrospective study including 34 eyes of 34 patients (7 women and 27 men) with treatment-nave central serous chorioretinopathy (CSC) and 33 eyes of 17 patients (7 women and 10 men) with Vogt-Koyanagi-Harada disease (VKH) or sympathetic ophthalmitis (SO) were ...

    6. Denoising Swept Source Optical Coherence Tomography Volumetric Scans using a Deep Learning Model

      Denoising Swept Source Optical Coherence Tomography Volumetric Scans using a Deep Learning Model
      Purpose: To evaluate the use of a deep learning (DL) noise-reduction model on swept source optical coherence tomography (SS-OCT) volumetric scans. Methods: Three groups of images including single-line highly averaged foveal scans (Averaged images), foveal B-scans from volumetric scans using no averaging (Unaveraged images) and DL denoised versions of the latter (Denoised images) were obtained. We evaluated the potential increase in signal to noise ratio by evaluating the contrast to ...

    7. Ophthalmic apparatus and ophthalmic optical coherence tomography method

      Ophthalmic apparatus and ophthalmic optical coherence tomography method
      An ophthalmic apparatus according to an embodiment includes a fixation system, a data acquisition device, analyzing circuitry, and controlling circuitry. The fixation system projects fixation light onto a subject's eye. The data acquisition device acquires data by applying optical coherence tomography scanning to the subject's eye onto which the fixation light is being projected. The analyzing circuitry analyzes the data to specify the position of a predetermined site ...

      Ophthalmological device
      In an ophthalmological device, a memory stores a three dimensional data set acquired by applying OCT to a subject's eye. A fourth color coding unit assigns color information according to a depth position to the three dimensional data set. A fourth layer region identifying unit identifies layer regions by applying segmentation to the three dimensional data set, A fourth blood vessel region extracting unit extracts a blood vessel region ...
