title: [Measurement of retinal nerve fiber layer thickness of normal eyes with nerve fiber analyzer].
abstract: OBJECTIVE
  To study the retinal nerve fiber layer thickness (RNFLT) of normal eye and the correlation with age.
  
  
  METHODS
  RNFLT of 198 cases of normal eyes were examined by using nerve fiber analyzer (NFA).
  
  
  RESULTS
  There were significant inverse linear correlation between the RNFLT and age (r = -0.46, P < 0.01). In the analysis by the quadrant, the RNFLT was correlated with age in the superior and inferior quadrant. The mean ratio of superior and inferior quadrant thickness (S/I) was 1.041.
  
  
  CONCLUSIONS
  NFA seems to be an useful tool to measure the RNFLT quantitatively. The RNFLT of normal eye is found to be decreased with age.
