title: Quality of life in patients with age-related macular degeneration: results from the VISION study.
abstract: OBJECTIVE
  To assess the impact of treatment with pegaptanib sodium vs usual care on vision-related quality of life (VRQoL) in patients with age-related macular degeneration (AMD).
  
  
  METHODS
  VRQoL was a secondary end point in the trial, a prospective, randomized, double-masked, multicentre, dose-ranging study. Three doses of pegaptanib (0.3, 1, and 3 mg) were compared with usual care with respect to changes in VRQoL as indicated by the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ 25), administered at baseline and weeks 30 and 54. Four of the NEI-VFQ 25 domains were prospectively designated as primary: near vision, distance vision, role limitations, and dependency. Between-group differences were assessed using an analysis of covariance model with age, gender, and baseline score as covariates.
  
  
  RESULTS
  NEI-VFQ 25 data were available for 569 subjects. At week 54, improvements in the distance vision and role limitations domains were greater in pegaptanib than usual care arms. No substantial increase in ocular pain was noted in pegaptanib-treated patients. No clear superiority of any particular dosage strength of pegaptanib was demonstrated, and no significant differences or trends favoured usual care on any domain score or the NEI-VFQ 25 composite score. The greatest VRQoL benefit was seen in responders (lost<3 lines) to treatment.
  
  
  CONCLUSIONS
  The VISION trial provided evidence of trends in quality-of-life benefit associated with effective treatment of AMD using pegaptanib. Treatment with pegaptanib is expected to contribute significantly to VRQoL improvement for responder patients.
