    1. Measurable Range of Subfoveal Choroidal Thickness With Conventional Spectral Domain Optical Coherence Tomography

      Measurable Range of Subfoveal Choroidal Thickness With Conventional Spectral Domain Optical Coherence Tomography

      Purpose : We investigate the measurable range of subfoveal choroidal thickness (SFCT) with conventional spectral domain optical coherence tomography (SD-OCT) in normal healthy eyes. Methods : All subjects underwent an SD-OCT horizontal line scan centered at the fovea with standard and enhanced depth imaging (EDI) techniques. Two independent observers manually measured SFCT on standard and EDI-OCT images, if two choroidal borders were identified. The rate of successful measurement with standard OCT was evaluated. Inter- and intraclass correlation coefficients and Bland-Altman plots were used for analysis. Results : OCT images of 724 normal healthy eyes from 374 subjects were evaluated. Although the inner choroidal ...

    2. Association between Systemic Hypertension and Macular Thickness Measured by Optical Coherence Tomography

      Association between Systemic Hypertension and Macular Thickness Measured by Optical Coherence Tomography

      Purpose: This study aimed to evaluate an association between hypertension and macular thickness. Methods: Eight hundreds and twenty-seven Korean adults composed of 163 pairs of twins and their family members were included in this population-based cross-sectional study. Macular thickness was measured with optical coherence tomography at nine macular subfields defined by the Early Treatment of Diabetic Retinopathy Study. Cardiometabolic risk factors, including body mass index (BMI), hypertension, diabetes, lipid profiles, and smoking status, were assessed. Linear mixed regression analysis was conducted with consideration of familial correlations and adjustment for covariates. Results: Age-, sex-, and axial length-adjusted analysis showed that systemic ...
