Ventura LO, et al. - Researchers evaluated the visual impairment in a large sample of infants with congenital Zika syndrome (CZS) and compared with a control group using the same assessment protocol. The mean age of the CZS group at examination was 8.5 ± 1.2 months; of the controls, 8.4 ± 1.8 months. Findings demonstrated that severe visual impairment was presented by infants with CZS. For assessment of the ocular findings, visual acuity, and visual developmental milestones tested against age-matched controls, a protocol was suggested. Compared to controls, the visual development milestones were less achieved by infants with CZS.
