목적 : To determine the prevalence of disc hemorrhage in a large Korean population based on the data from the nationwide cross-sectional survey, the Korea National Health and Nutrition Examination Survey (KNHANES).
방법 : We performed a retrospective review of the KNHANES dataset covering January 2012 to December 2012. The study population comprised 5,612 subjects (≥ 19 years of age), who completed a comprehensive glaucoma evaluation (including Goldmann applanation tonometry, fundus photography, and frequency doubling perimetry). Two masked graders evaluated fundus photography to detect the disc hemorrhage (DH). The prevalence of DH in each subject was defined as the presence of DH at least in one eye.
결과 : In a total of 5,612 subjects, 292 (5.20%) were diagnosed as a glaucoma, and 29 (0.52%) had a DH. In glaucomatous subjects, the prevalence of DH was 4.11% (12 subjects), which was significantly higher than that of 5,320 non-glaucomatous subjects (0.32%, 17 subjects; P <0.001). In glaucomatous subjects with DH, refractive errors were more myopic than those without DH (-0.79 ± 0.76 vs -0.61 ± 2.55 diopter, P = 0.049). In multiple regression analysis, it revealed that the presence of DH was not significantly correlated with age, gender, refractive error, and IOP in glaucomatous subjects.
결론 : In the general Korean population, the prevalence of DH was 0.52%, and that of DH in glaucomatous subjects was 4.11%.
