title: Apolipoprotein E polymorphisms in patients with primary open-angle glaucoma.
abstract: OBJECTIVE
  To investigate apolipoprotein E (APOE) polymorphisms, which are known to influence the risk of Alzheimer disease (AD), in patients with primary open-angle glaucoma (POAG).
  
  
  METHODS
  Retrospective case-control association study.
  
  
  METHODS
  Patients with POAG (n = 242) and controls (n = 187) were analyzed for the APOE epsilon 2/epsilon 3/epsilon 4 polymorphisms using minisequencing technique.
  
  
  RESULTS
  The Alzheimer-associated APOE epsilon 4 allele had similar frequencies in the POAG group and in the control group. There was no difference between cases and controls with regard to APOE genotypes.
  
  
  CONCLUSIONS
  If a common pathogenic mechanism exists for the two age-related neurodegenerative diseases, POAG and AD, it does not involve APOE polymorphisms.
