Purpose: To describe the prevalence of vitreoretinal diseases in the Korean population 50 years or older at a health screening center.
Methods: The participants of this study included 11,180 adults 50 years of age and older who visited the Health Promotion Center of Kangbuk Samsung Hospital from January to December 2006. Digital images of non-mydriatic fundus photographs were examined. We calculated the sex- and age-adjusted prevalence of vitreoretinal diseases using the direct standardized method based on the number of resident registrations.
Results: The age- and sex-adjusted prevalence of vitreoretinal diseases in Korean adults 50 years of age and older was 9.9%. The prevalence of vitreoretinal diseases significantly increased with age (P=0.000). There was no significant gender difference in the prevalence of vitreoretinal diseases (p=0.553). Age-related macular degeneration was the most common vitreoretinal disease, with an age- and sex-adjusted prevalence of 5.2%. Epiretinal membrane, retinal vein occlusion, and diabetic retinopathy were common vitreoretinal diseases in that order, and the age- and sex-adjusted prevalences were 1.5%, 1.1%, and 0.9%, respectively.
Conclusions: The prevalence of vitreoretinal diseases in a screened Korean population 50 years and older was 9.9%. Vitreoretinal diseases are a major ophthalmic problem in Korea. As the Korean population continues to age and the prevalence of diabetes increases, further investigations about the epidemiology and prevention of vitreoretinal diseases are needed.
