All patients underwent a comprehensive ophthalmologic examination and PR-VEP was performed binocularly in a room with constant dim illumination. The P100 peak time in the 60' arc stimuli was used, and the results were correlated with visual acuity, cephalic perimeter at birth, and funduscopic findings.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              Thirty-seven children were included in the congenital Zika syndrome group and 15 in the control group. The mean age was 18.5 \u00b1 0.9 months (range: 17 to 20 months) in the congenital Zika syndrome group and 24.3 \u00b1 1.6 months (range: 21 to 28 months) in the control group. The P100 response was normal in 7 patients (18.9%) with congenital Zika syndrome, borderline in 2 (5.4%), abnormal with prolonged latency in 18 (48.6%), and abnormal with no response in 10 (27.0%). A significant correlation between the visual acuity and P100 peak time was observed (\n              <jats:italic>P<\/jats:italic>\n              &lt; .001). The P100 values were not correlated significantly with the cephalic perimeter at birth (\n              <jats:italic>P<\/jats:italic>\n              = .412) or the funduscopic findings (\n              <jats:italic>P<\/jats:italic>\n              = .510). PR-VEP in children with congenital Zika syndrome and no funduscopic findings was significantly worse than in the control group (\n              <jats:italic>P<\/jats:italic>\n              = .001).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>Children with congenital Zika syndrome have characteristically abnormal PR-VEPs regardless of the funduscopic findings and severe microcephaly.
