Method: A cross-sectional survey was conducted Between September and December 2014 to assess the prevalence and risk factors for OSDI.
Results: The OSDI average value was 40.46 ± 23.62 points, with 86.4% of patients (1967) having a OSDI score higher than 12 points. Women had OSDI symptoms more frequently than men (odds ratio: 1.17; 95% confidence interval: 1.08-1.28) and higher OSDI score (42.12 ± 24.03 vs. 38.01 ± 22.81 points). Patients without disease were younger than the patients with severe disease (45.30 ± 18.32 vs. 50.62 ± 18.86).
Conclusions: Ophthalmological patients have a prevalence of 80.4% of OSDI. Female and older age was associated with ocular surface disease.
