Importance: Most ocular lesions have been described for children with congenital Zika syndrome. The frequency of finding ocular abnormalities is unknown among children exposed to Zika virus (ZIKV) during pregnancy. This study was conducted on newborns whose mothers were positive for ZIKV, confirmed with reverse-transcription polymerase chain reaction (RT-PCR) testing.

Introduction: Didanosine is an adenosine analog, part of the nucleoside reverse-transcriptase inhibitor family. Since the description of didanosine-induced retinopathy in the early 1990s, little is known about the progression of this toxic retinopathy and the putative underlying mitochondrial defect.
Objectives: We report long-term follow-up for cases of didanosine-induced retinopathy and discuss a new hypothesis for pathophysiology based on the alteration of endogenous adenosine on the photoreceptor outer segment turnover and phagocytosis by the retinal pigment epithelium.

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.
