ABSTRACT
Purpose:
To estimate the prevalence and risk factors of dry eye disease symptoms and clinical diagnoses in Sao Paulo city, state of Sao Paulo, Brazil.
Methods:
A total of 582 participants over 18 years old, living in the east zone of Sao Paulo city responded to a short questionnaire. Dry eye disease was on that is defined by the presence of severe symptoms or previous clinical diagnosis of dry eye disease by an ophthalmologist. The association between dry eye disease and possible risk factors was assessed.
Results:
Overall dry eye disease severe symptoms and/or clinical diagnoses prevalence was calculated as 24.4% for both sexes. Women presented a higher frequency of severe symptoms of dry eye disease (16.07%) than men (8.48%; p=0.0244), as well as the composite of severe symptoms or diagnosed dry eye disease, presented by 26.86% of women and 18.18% of men (p=0.0366). In women, ages between 55 to 75 years old were associated with dry eye disease severe symptoms (OR=3.11; 95%CI 1.56-6.23, p=0.001) and diagnosed dry eye disease (OR=2.02; 95% CI 1.04-3.93, p=0.037). Hypertension was significantly associated with dry eye disease symptoms (OR=1.98; 95% CI 1.14-3.43, p=0.015) and diagnoses (OR=3.54; 95% CI 1.92-6.53, p=0.0001) in women. Eye drops use was associated with severe symptoms of dry eye disease and diagnosed dry eye disease in both women and men (p≤0.01).
Conclusions:
Dry eye disease prevalence in Sao Paulo city is higher in women than in men. Age and hypertension were stronger risk factors of dry eye disease for women, while eye drops use was a significant indicator of dry eye disease for both sexes.
