    1. Classification of optical coherence tomography images using a capsule network

      Classification of optical coherence tomography images using a capsule network

      Background Classification of optical coherence tomography (OCT) images can be achieved with high accuracy using classical convolution neural networks (CNN), a commonly used deep learning network for computer-aided diagnosis. Classical CNN has often been criticized for suppressing positional relations in a pooling layer. Therefore, because capsule networks can learn positional information from images, we attempted application of a capsule network to OCT images to overcome that shortcoming. This study is our attempt to improve classification accuracy by replacing CNN with a capsule network. Methods From an OCT dataset, we produced a training dataset of 83,484 images and a test ...

    2. Wavy and elevated retinal pigment epithelial line in optical coherence tomographic images of eyes with atypical Vogt-Koyanagi-Harada disease

      Wavy and elevated retinal pigment epithelial line in optical coherence tomographic images of eyes with atypical Vogt-Koyanagi-Harada disease

      Purpose We report the changes of the retinal pigment epithelium (RPE) determined by optical coherence tomography in a patient with atypical Vogt–Koyanagi–Harada (VKH) disease during the recovery phase. Method Case presentation. Results A 74-year-old woman presented with a central scotoma associated with disc hyperemia, serous retinal detachment, and scleral thickening in her left eye, and was diagnosed with VKH. OCT showed a serous retinal detachment and a wavy RPE contour that corresponded to the choroidal folds. The OCT images clearly showed the dynamic changes of the retina, RPE, and choroid during the recovery phase. Conclusions The OCT was ...

    3. Technical Note: Method for estimating volume of subretinal fluid in cases of localized retinal detachment by OCT ophthalmoscopy

      The volume of the subretinal fluid can be used to assess the condition of different types of retinal and macular disorders. The purpose of this report is to introduce a method to measure the volume of the subretinal fluid with the images of the optical coherence tomography (OCT) Ophthalmoscope in three cases of central serous chorioretinopathy and one case of retinal pigment epithelial detachment. We used the topography-mode program of the OCT Ophthalmoscope and measured the average height of the retinal detachment. By multiplying the size of the area of the retinal detachment and the average height of the retinal ...
