title: Correlation of visual function with health-related quality of life in glaucoma patients.
abstract: OBJECTIVE
  The purpose of this study was to assess visual impairment and quality of life (QOL), the relationship between visual function and health-related and vision-related QOL, and to identify factors significantly impacting QOL for glaucoma patients.
  
  
  METHODS
  One-on-one interviews of 280 glaucoma patients at a regional hospital in Taiwan from 1 April 2005 to 30 September 2005. Data collected included demographics, clinical examinations and treatment status. QOL data collected utilized the Chinese (Taiwanese) version of the Medical Outcomes Study Short-Form 36 Health Survey (SF-36) and the National Eye Institute Visual Function-25 (NEIVFQ-25).
  
  
  RESULTS
  The majority of study participants had open-angle glaucoma (54.3%) and were classified as moderate stage (33.6%). The higher the health-related QOL scores for both questionnaires, the fewer difficulties experienced by the patients. Moderate correlation was found between the SF-36 and NEIVFQ-25 subscales and visual function. Significant predicting factors for the SF-36 were gender, age, employment status, presence of systemic disease, better-eye visual acuity and better-eye mean defect. For the NEIVFQ-25, these were general vision, near and distance activities, colour vision and peripheral vision scores.
  
  
  CONCLUSIONS
  A combination of demographic data, clinical examination and QOL questionnaires may help clinicians better ascertain the impact of disease severity on glaucoma patients' QOL. This information may help in patient education, treatment compliance and selection of treatment options.
