title: [Visual function evaluation in human immunodeficiency virus carriers].
abstract: OBJECTIVE
  To determine whether there are changes in the peripapillary nerve fibre layer, in colour vision, contrast sensitivity, dark adaptation and electroretinography changes in these patients who do not have infectious retinitis.
  
  
  METHODS
  We studied 52 patients without ocular pathology; the mean age was 35.88 years old.
  
  
  RESULTS
  We observed less thickness in all quadrants, except the nasal. The colour vision was altered in 27.77% of the patients. The contrast sensitivity test showed high frequency alterations. There was no statistically significant difference in the electroretinography test or in dark adaptation.
  
  
  CONCLUSIONS
  There are changes in the peripapillary nerve fibre layer thickness; also we found changes in colour vision, contrast sensitivity and a decreasing trend of the B wave in the electroreninogram.
