PURPOSE: To describe and analyze ocular features in infants with microcephaly due to presumed congenital Zika syndrome.
METHODS: Ophthalmologic evaluation, including indirect ophthalmoscopy and eye fundus imaging, visual acuity testing with Teller Acuity Cards, and strabismus assessment were performed in infants with microcephaly at a nongovernmental organization clinic for visually disabled children.
RESULTS: A total of 70 infants with microcephaly were referred to the clinic. Of these, 25 (mean age, 3 months; 14 males) had ophthalmologic changes: 18 (26%) had intraocular abnormalities, including macular chorioretinal atrophy, mottled retinal pigment epithelium and optic nerve pallor; 7 patients (10%) had strabismus or nystagmus without intraocular abnormalities. Visual acuity was below normal range in all 11 infants tested.
CONCLUSIONS: Ophthalmologic abnormalities occurred in 36% of the patients. Macular circumscribed chorioretinal atrophy, focal mottled retinal pigment epithelium, optic nerve pallor, early-onset strabismus, nystagmus and low visual acuity were common ophthalmological features in infants with microcephaly due to presumed congenital Zika syndrome.
