title: Basic tear secretion measurement in pterygium.
abstract: OBJECTIVE
  To evaluate the correlation between dry eye and pterygium.
  
  
  METHODS
  A prospective study of basic tear secretion in 30 patients who had unilateral pterygium was performed. Schirmer's test with anesthesia was assessed in both eyes of patients with unilateral pterygium.
  
  
  RESULTS
  Mean Schirmer's test value in the eye with pterygium was 11.6 +/- 0.4 mm and 12.4 + 0.4 mm, without pterygium. The Schirmer's test value was decreased significantly in the eye with pterygium.
  
  
  CONCLUSIONS
  This study revealed that the Schirmer's test value with anesthesia was decreased significantly in the eye with unilateral pterygium when compared with a healthy eye.
