Background: Dry eye disease is a multifactorial chronic disorder of the ocular surface, which leads to symptoms of discomfort and distress. Dry eye disease is a global health concern and is one of the most frequent ocular diseases encountered in an ophthalmology clinic. The estimated prevalence of dry eye disease in the literature ranged from 7.4% to 93.2%. Saudi Arabia's population, especially in the eastern province, is at great risk of developing dry eye disease, however, there is hardly any nationwide study that assesses the prevalence of dry eye disease among the general population and its risk factors.Aim: The aim is to estimate the prevalence of dry eye disease and determine its risk factors among the general population of Saudi Arabia.Methods: This study was a cross-sectional study conducted on the general population of Saudi Arabia between September 2022 and November 2022. A convenient sampling technique was deployed for participant recruitment, where a self-administered questionnaire was created and dispersed to the general population all over the country with an invitation to participate in the study. Dry eye disease prevalence was assessed using Ocular Surface Disease Index survey. The Chi-square test was used to test for factors associated with the prevalence of dry eye disease, and undiagnosed dry eye disease. Multivariate logistic regression was also used to determine risk factors for dry eye disease.Results: A total of 1,381 participants were included in this study. The prevalence of dry eye disease among the general population of Saudi Arabia was observed to be (17.5%). Among the participants (11%) had mild dry eye disease, (4.7%) had moderate dry eye disease, and (1.7%) had a severe dry eye disease. Among those observed to have a dry eye disease, (58.09%) were not previously diagnosed. The following factors were observed to be significantly associated with having dry eye disease, being female, having thyroid disease, having systemic lupus erythematosus/rheumatoid arthritis, using antidepressants, using antihistamine/decongestants, using electronic devices for a prolonged time, using contact lenses, having a history of eye surgery, history of conjunctival/eyelid infection, and history corneal abrasions/erosions/ulceration. Conclusion: This study revealed that the prevalence of dry eye disease among the general population of Saudi Arabia is notably lower than what was observed in other local studies and similar to what was found in some global studies. Adjusted binary multivariate logistic regression revealed that the risk factors were only: being female, using antidepressants, using antihistamines/decongestants, and prolonged use of electronic devices.
