Ophthalmological examination and VEPs in preterm children with perinatal CNS involvement

Abstract

In preterm children (gestational age of 26-29 weeks) with perinatal posthemorrhagic hydrocephalus, visual evoked potentials (VEPs) to pattern and motion stimuli were examined at ages 4 - 11 years. In all eyes pathological VEPs changes were found irrespective of about normal visual functions in some of them.

Motion-onset VEPs were more sensitive, which suggests a more significant involvement of the magnocellular system/dorsal stream of the visual pathway.
