title: Central corneal thickness and visual field loss in fellow eyes of patients with open-angle glaucoma.
abstract: OBJECTIVE
  To determine the relationship of central corneal thickness (CCT) and visual field loss between fellow eyes in primary open-angle glaucoma.
  
  
  METHODS
  Retrospective, observational case series.
  
  
  METHODS
  Records review of glaucoma patients seen at local Veterans Administration eye clinic. Those with CCT measurements performed within one month of visual field testing were included. Patients were excluded with vision below 20/40 or disease that would affect visual fields. Intrasubject (between fellow eyes) differences in CCT, mean deviation (MD), and pattern standard deviation (PSD) were calculated by subtracting left eye value from right eye value.
  
  
  RESULTS
  Of the 100 subjects (94 males), the Spearman correlation coefficient between intrasubject differences in CCT vs intrasubject differences in MD was 0.36 (P = .0003). The Spearman correlation for differences in CCT vs differences in PSD was -0.31 (P = .0019).
  
  
  CONCLUSIONS
  Our study suggests that worse visual field changes tend to occur in the eye with the thinner cornea.
