Abstract
Purpose: To report fundamental epidemiologic data for choroidal parameters such as choroidal thickness and index of choroidal vascularity in Japanese individuals and to evaluate their correlations with age, sex, systemic parameters, and other ocular parameters. Design: Population-based cohort study. Participants: A total of 9850 individuals participated in the first follow-up of the Nagahama Prospective Cohort for Comprehensive Human Bioscience (the Nagahama Study) conducted between 2013 and 2016. Methods: , and CVI, their associations with age, sex, axial length (AL), and spherical equivalent (SE) were evaluated using linear regression analysis with adjustments for possible confounders. Main Outcome Measures: , and CVI in the healthy Japanese population and their characteristics. Results: < 0.001). Conclusions: and CVI suggested that younger individuals have a more lumen-rich choroid for their choroidal thickness than older individuals.
