Objective: To describe the prevalence and one-year incidence of retinal vein occlusion (RVO) and associated risk factors in a Japanese population at a medical checkup institution in Osaka.
Methods: Fundus photography was performed on 28,781 participants aged 19–93 from April 2019 to March 2020 as part of the medical checkup. We determined the prevalence of RVO, including central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) by assessing the photographs, and analyzed the associated risk factors for RVO using medical checkup data.
Results: Of the 28,781 participants, RVO, BRVO, and CRVO were found in 334, 311, and 23 participants with 1.2%, 1.1%, and 0.08% prevalence, respectively. New RVO, BRVO, and CRVO were found in 57, 52, and 5 participants with a one-year incidence of 0.2%, 0.18%, and 0.02%, respectively. According to multivariate logistic regression analyses of subjects with and without RVO, there was a significant difference in the age, with an odds ratio (OR) of 1.03 (95% confidence interval [CI]=1.01–1.04); hypertension (OR=2.56, 95%CI=1.90–3.44); and AV nicking (mild: [OR=9.73, 95%CI=2.3–41.1]; moderate: [OR=298, 95%CI=73.6–1,210]; and severe: [OR=1,210, 95%CI=289–5,080]); respectively.
Conclusions: The prevalence of RVO was 1.2% and the one-year incidence of RVO was 0.2%. The strong correlation between RVO and the risk factors of hypertension and AV nicking suggests that blood pressure control and the prevention of arteriosclerosis would be associated with a lower incidence and prevalence of RVO.
