title: Comparison of a five-degree visual field between two programs of different testing field range.
abstract: OBJECTIVE
  A five-degree visual field with two programs of different testing field size was studied, and the visual fields between them were compared.
  
  
  METHODS
  Observational study.
  
  
  METHODS
  Forty-six patients with open-angle glaucoma were tested by Humphrey field analyzer (Carl Zeiss Meditec, Inc, Dublin, California, USA) programs 30-2 full threshold and 10-2 full threshold. Forty reliable results with both programs were analyzed.
  
  
  RESULTS
  Sensitivity of the same position within a five-degree field was significantly higher with the 10-2 program than with the 30-2 program. Higher sensitivity within a five-degree field with the 10-2 program significantly correlated with that with the 30-2 program.
  
  
  CONCLUSIONS
  Visual field determined by automated perimetry was influenced by testing field size.
