Abstract

The neurological outcome for infants with Grade I/II intraventricular hemorrhage (IVH) is debated. The aim of this study was to determine whether very low birth weight infants (VLBW, <1500 g) with grade i ii (ivh) have altered visuocortical activity compared infants no ivh. we assessed the quantitative swept parameter visual evoked potential (svep) responses by three different stimuli. data from 52 vlbw were 13 or ivh, enrolled at 5-7 months corrected age. acuity thresholds and suprathreshold response amplitudes compared. grating (ga), contrast sensitivity (cs) vernier (va) each worse in ivh groups (8.24 cpd group vs. 13.07 for ga; 1.44% 1.18% cs 1.55 arcmin 0.58 va). slopes of amplitude va significantly lower infants. spatial frequency tuning function was shifted downward on axis, without a change slope. these results indicate that are associated deleterious effects cortical vision development function. free pmc article. pmcid: pmc4500802 < p>
