title: [Changes in the visual system in low birth weight children].
abstract: OBJECTIVE
  Evaluation of the visual system, especially refraction, in children with low birth weight under observation between 1990-1992.
  
  
  METHODS
  248 children with birth weight 600-2500 g and gestational age 26-37 weeks underwent ophthalmological examination including USG, ERG and VER. The children were first examined between 3-4 weeks of life, then at 8 and 12 weeks and 6, 12, 18 and 24 months.
  
  
  RESULTS
  Refractive errors were found in 216 of patients, in 85.2% hypermetropia. ROP occurred in 7 children with birth weight below 1500 g and gestational age 27-32 weeks. Other ocular changes were observed in 19 (7.6%) of the examined children.
