title: The effect of anisometropia on binocular visual function.
abstract: OBJECTIVE
  To investigate the effects of anisometropia on binocular vision.
  
  
  METHODS
  One to three dioptres of unilateral hyperopia, myopia or astigmatism was induced in 30 normal adults. The effect on binocularity was assessed with the Worth-four dot test, Titmus stereo test and Bagolini's lenses.
  
  
  RESULTS
  Binocular vision deteriorated with increasing anisometropia. Spherical anisometropia was more deleterious than astigmatic anisometropia.
  
  
  CONCLUSIONS
  In addition to amblyopia, the potential effect of anisometropia on binocular vision should be considered while prescribing spectacles in young children during the sensitive period.
