title: [Screening of selected parameters of visual system in children at the age of 6 to 10 in Great Poland area].
abstract: OBJECTIVE
  The goal of the work was to analyze parameters of visual system in children from Great Poland territory. Research covered: visual acuity and phoria at distance, stereo near vision, colour vision, near point of convergence, plus lens test.
  
  
  METHODS
  1138 children at the age of 6-10 years were examined, including 88 students in their spectacles. During the examination C-Landolt plates, +1.00 lens, Titmus Stereo Fly test, Ishihara plates, fixation ball and Maddox rod were used.
  
  
  RESULTS
  At least 70% children passed particular tests, but the whole examination was passed by only 40% children (in glasses 45% and 15%, respectively); among children who failed plus lens test, 36% did not pass stereotest; 12% of children (35% in glasses), failed stereotest and reached different visual acuity in both eyes, which can cause binocular dysfunction.
  
  
  CONCLUSIONS
  It is necessary to expand the scope of the school vision screening in school children using additional parameters connected with far and near vision and binocular vision.
