Abstract

PURPOSE
To investigate the prevalence, clinical manifestations, and risk factors of dry eye syndrome (DES) among people over 50 years old in the Incheon area.
METHODS
A cross-sectional prevalence study was performed on 462 people over 50 years old in Dong-gu, Incheon. DES was defined as the constant or frequent presence of symptoms of both dryness and irritation. Symptoms and past medical history were assessed by a survey. Eye examination included slit lamp examination, Schirmer test, and tear break-up time (T-BUT). Age, sex, living habits, systemic and eye diseases were also analyzed to determine the risk factors of DES.
RESULTS
The prevalence of DES was 26.2%. The major symptoms were as follows in descending order: dryness (77.9%), tearing (75.2%), and sandiness (72.7%). An average of 12.1 +/- 6.0 mm in the Schirmer test and 6.7 +/- 2.4 seconds in the T-BUT were significantly different in the DES group from the normal group (p < 0.001). Variables such as age, sex, living habits, and eye diseases were not related to the diagnosis of DES, whereas diabetes was the only risk factor of DES with statistical significance (p = 0.03).
CONCLUSIONS
In the present study, the prevalence of DES among people over 50 years old in the Incheon area was 26.2%. Schirmer test and T-BUT were considered to be helpful tools for the diagnosis of DES, and diabetes was a significant risk factor of DES.
