Abstract
Background: Dry eye syndrome is a common worldwide problem that can decrease the quality of life and vision among the general population. The prevalence of dry eye varied according to diagnostic criteria, population, and age distribution. Information on the prevalence and risk factors of dry eye can be used to ensure that the appropriate treatment for dry eye patients and the general population are administered correctly.
Objective: Determined the prevalence and risk factors for dry eye syndrome in Thai population.
Methods: Six hundred twenty five subjects between the ages of 50 to 90 were recruited from the Romklao District, Bangkok, Thailand. Subjects were interviewed to assess whether they currently have symptoms of dry eyes, grade the severity, and to determine the risk factors. Associations between dry eyes and risk factors were determined by binary logistic regression.
Results: Out of 625 subjects, 89 subjects (14.2%) had dry eye syndrome. The prevalence of dry eyes was greater in females (16.6%) compared to males (10.6%), p = 0.029. Dry mouth symptoms, allergic history, and previous eye surgery were significantly associated with dry eyes (p = 0.005, 0.013, <0.001, respectively).
Conclusion: Prevalence of dry eyes in the elderly Thai population is 14.2% in our urban study.
