    1. A New Optical Coherence Tomography Method for Subfoveal Choroidal Thickness Measurement: A Singlecenter Observational Study

      A New Optical Coherence Tomography Method for Subfoveal Choroidal Thickness Measurement: A Singlecenter Observational Study

      Background : Several macular pathologies are associated with choroidal vascular supply, and thus require choroidal thickness evaluation. However, there is no standard subfoveal choroidal thickness (SFCT) measuring method. This study investigated a new method to measure the SFCT, using optical coherence tomography. Methods : This is a single-center observational study. Eighty-two senior medical students participated as observers and independently measured the SFCT on five standard optical coherence tomography images of healthy adults in a tertiary care setting. They used three different methods: (1) the observer’s own method, (2) the conventional method, perpendicular to the retinal pigment epithelium, and (3) the new ...

    2. Outer Retinal Layers Alterations in Chronic Central Serous Chorioretinopathy: Spectral Domain-OCT and Fundus Autofluorescence Findings

      Outer Retinal Layers Alterations in Chronic Central Serous Chorioretinopathy: Spectral Domain-OCT and Fundus Autofluorescence Findings

      Purpose To document alteration of the outer retinal layers and fundus autofluorescence (FAF) change in eyes with chronic central serous chorioretinopathy (CSCR). Methods Seventeen eyes of fifteen patients diagnosed with chronic CSCR from January 2014 to March 2015 with at least 6 months of follow-up and no history of surgery were enrolled in this study. Morphologic alterations in the retinal pigment epithelium (RPE), the photoreceptor inner segment/outer segment (IS/OS) junction layer, and the outer retina were evaluated by Spectral domain optical coherence tomography (SD-OCT). The FAF images were obtained via Heidelberg Retina Angiogram using a view mode of ...

    3. Choroid in Myopic Choroidal Neovascularization Measured Using SD-OCT

      Choroid in Myopic Choroidal Neovascularization Measured Using SD-OCT

      Purpose Using the spectral domain optical coherence tomography (SD-OCT), we studied the difference in the choroidal morphology between the choroidal neovascularization (CNV) area and the area surrounding CNV. Methods This retrospective study consisted of 19 patients with myopic CNV lesion in eye; fellow eyes were used as controls. All eyes were analyzed by measuring the choroidal thickness and large choroidal vessel size using SD-OCT. Eyes with CNV were divided into groups; the neovascular lesion was defined as group 1, the surrounding area as group 2. Subfovea of the fellow eye was defined as group 3. Results The choroidal thickness was ...
