Summary

The aim of this research is to evaluate visual functions in premature children who have suffered perinatal brain injury. This study includes children with intraventricular haemorrhage, periventricular leukomalatia, brain atrophy and posthaemorrhagic hydrocephalus, who required surgery. In addition to the general assessment, the following parameters were also evaluated during ophthalmology examination: visual acuity, refractive errors, strabismus. Only 35.4% of children had normal visual acuity. Refractive errors were identified in 55.8% of patients, hypermetropy prevailed (85.7% of all children with refractive disorders). Strabismus was found in 47.9% of children. These results suggest that premature children with brain injury should have regular ophthalmology assessment with early correction of their visual defects.

Key words:
premature children – posthemorrhagic hydrocephalus – periventricular leukomalatia – intraventricular haemorrhage – visual functions
