Ocular manifestations in Congenital Zika syndrome: About a case of torpedo maculopathy

PURPOSE: To describe pertinent imaging studies and clinical features of a torpedo maculopathy presumably associated with congenital Zika syndrome. OBSERVATION: A 23-month-old child, with no prematurity or microcephaly at birth, was examined in the Ophthalmology department of the University Hospital of Fort-de-France (Martinique, French West Indies), as part of a systematic screening of malformations in children suspected of maternal-fetal exposure to Zika virus. Zika infection was confirmed in the mother's serum by Reverse Transcriptase Polymerase Chain Reaction during the third trimester of pregnancy. Fundus examination found a unilateral hypopigmented retinal lesion, temporal to the macula, with an apex pointing to the fovea. Explorations in spectral-domain optical coherence tomography showed a subretinal cleft with broadening and attenuation of the interdigitation zone, elevation of the outer limiting membrane and the ellipsoid zone, without thinning of the outer retinal layers. CONCLUSION AND IMPORTANCE: There is a proven risk of congenital eye defects after Zika infection during pregnancy. We report here the first case of torpedo maculopathy without microcephaly, in a child suspected of maternal-fetal exposure to Zika.
