title: Vision screening for frail older people: a randomised trial.
abstract: OBJECTIVE
  To assess the effects of vision screening, and subsequent management of visual impairment, on visual acuity and vision-related quality of life among frail older people.
  
  
  METHODS
  Randomised controlled trial.
  
  
  METHODS
  Community in Sydney, Australia.
  
  
  METHODS
  616 men and women aged 70 years and over (mean age 81 years) recruited mainly from people attending outpatient aged care services.
  
  
  METHODS
  No vision assessment or intervention
  
  
  METHODS
  Comprehensive vision and eye examinations conducted by an optometrist. Three hundred subjects were seen by the study optometrist, with 146 judged to need treatment for a vision or eye problem. The optometrist arranged new glasses for 92 subjects; 24 were referred for a home visit by an occupational therapist; 17 were referred for glaucoma management; and 15 were referred for cataract surgery.
  
  
  METHODS
  Distance and near visual acuity (logMAR) and composite scores on the 25-item version of the National Eye Institute Visual Function Questionnaire, both assessed at a 12-month follow-up home visit.
  
  
  RESULTS
  After 12 months' follow-up, the mean (logMAR) distance visual acuity was 0.27 in the intervention group and 0.25 in the control group (p = 0.32). The mean (logMAR) near visual acuities were -0.01 in the intervention group and -0.03 in the control group (p = 0.26). The mean composite score on the National Eye Institute Visual Function Questionnaire was 84.3 in the intervention group and 86.4 in the control group (p = 0.49).
  
  
  CONCLUSIONS
  Vision screening by an optometrist for frail older people living in the community in Australia does not lead to improvements in vision or vision-related quality of life after 1 year's follow-up.
