title: Associations between glaucomatous visual field loss and participation in activities of daily living.
abstract: OBJECTIVE
  This study investigated the association between visual field loss and participation in daily activities in individuals with glaucoma.
  
  
  METHODS
  Seventy-nine patients were recruited from the Royal Victorian Eye and Ear Hospital. Visual fields were assessed using the Esterman binocular visual field tests and participation in daily activities was assessed using the Impact of Vision Impairment (IVI) questionnaire. Visual acuity and contrast sensitivity were also measured.
  
  
  RESULTS
  There was no independent relationship between visual field loss and IVI score (r = -0.20; P = 0.09), except for the mobility domain (r = 0.25; P = 0.03). Mobility was the most affected domain of the IVI (mean = 1.2). Over a quarter of the patients reported experiencing moderate to severe restriction with mobility activities despite relatively minor binocular field loss.
  
  
  CONCLUSIONS
  Mobility is the area in which glaucoma patients encounter difficulties even when the visual field and visual acuity are relatively good. Questions related to mobility could be asked to identify those patients who need rehabilitation.
