title: Screening for depression in low-vision elderly.
abstract: OBJECTIVE
  To determine the sensitivity and specificity of the Geriatric Depression Scale (GDS) in older low-vision patients, and to compare GDS scores with the diagnosis of major depression in statistical models examining the interrelationships of vision, depression and disability.
  
  
  METHODS
  Cross-sectional survey.
  
  
  METHODS
  Community-residing older persons attending the low-vision clinic of Wills Eye Hospital, Philadelphia, PA, USA.
  
  
  METHODS
  Geriatric Depression Scale, DSM-III-R Checklist for Depression, Community Disability Scale and Snellen Visual Acuity.
  
  
  RESULTS
  The sensitivity and specificity of the GDS (GDS = 11) were 63% and 77%, respectively. A receiver operating characteristic curve showed that the GDS's ability to discriminate patients with and without major depression was no better than chance. Although the GDS was limited as a screen for major depression, it was useful in statistical models examining the interrelationships of vision, depression and disability.
  
  
  CONCLUSIONS
  Depressive symptoms are common among elderly patients with impaired vision attending a low-vision clinic. Although the GDS is unable to discriminate patients with and without major depression in this population, it is valuable as a continuous measure of depressive symptomatology to examine the interrelationships of vision, depression and disability.
