title: Optic disc size and other parameters from optical coherence tomography in Vietnamese-Americans.
abstract: OBJECTIVE
  To investigate the optic disc parameters by optical coherence tomography (OCT) in Vietnamese with various types of glaucoma.
  
  
  METHODS
  Medical charts of Vietnamese and White patients within a single practice were reviewed. Disc and rim areas by OCT were compared among nonglaucoma controls, different types of glaucoma, and glaucoma suspect. The association of these parameters with demographic and ocular features was evaluated.
  
  
  RESULTS
  Data from 1416 Vietnamese and 57 White patients were included. A larger mean disc area was observed in eyes with primary angle-closure glaucoma than in eyes with primary angle-closure and primary angle-closure suspect (both P<0.001). There was no association between disc size with central corneal thickness (P=0.051) and sex (P=0.155). Vietnamese patients with glaucoma and glaucoma suspicion had larger discs than diagnosis-matched Whites (P=0.043 and 0.021, respectively).
  
  
  CONCLUSIONS
  Vietnamese patients with glaucoma seem to have larger optic discs than White patients. Central corneal thickness had no association with disc area in this study population.
