Abstract: To determine the prevalence of pterygium and pinguecula and their determinants
Methods: This population-based cross-sectional study was conducted on geriatric population aged 60 and over in Tehran, Iran in 2019. Selected subjects were interviewed and subjected to optometric and ophthalmic examinations
Results: The age and sex standardized prevalence of pterygium and pinguecula in was 3.64% (95% CI: 2.94-4.49) and 55.57% (95% CI: 52.89-58.22), respectively. The prevalence of pterygium was 4.52% (95% CI: 3.5-5.81) in men and 2.79% (95% CI: 1.97-3.94) in women and the prevalence of pinguecula was 64.56% (95% CI: 60.92 - 68.03) in men and 46.72% (95% CI: 43.74 - 49.72) in women. According to the results of multiple logistic regression, pinguecula had a significant correlation with male sex (OR: 2.21, 95% CI: 1.63-2.99) and education level (OR: 0.52, 95% CI: 0.35-0.77) and pterygium had a significant relationship with male sex (OR: 2.2, 95% CI: 1.38-3.52), socioeconomic status (OR: 0.5, 95% CI: 0.26-0.97), education level (OR: 0.22, 95% CI: 0.08-0.61).
Conclusion: The prevalence of pinguecula and pterygium in this sudy were lower than other studies. Sex, socioeconomic status, and education level were the determinants of the prevalence of pinguecula and pterygium
