Design

Case Series at Tertiary Hospital

29 infants with microcephaly and presumed congenital Zika

2015: 1st Dec - 25 th Dec

Interventions

Wide field digital imaging

DDx of infections ruled out through serological and clinical examinations

Design and Interventions

23/29 mothers suspected Zika during pregnancy. Trimester: 18 = 1st; 4 = 2nd; 1 = 3rd.

58 eyes of 29 children

17 eyes of 10 children = Ocular Abnormalities

7/10 = Bilateral

Results

Examples

2 month old infant

RE: granular, pigmentary mottling in the macular.

LE: Chorioretinal lobulated atrophic lesion and slight pigmentary mottling

1 month old infant

RE & LE: paramacular supertemporal round chorioretinal atrophy surrounded by a hyper pigmented halo and hyper pigmented mottling

I month old infant

RE: enlarged cup-disc ratio and macular pigmentary mottling

LE: roundish macular chorioretinal atrophic lesion with a hyper pigmented halo and pigmentary mottling, as well as an enlarged cup-disc ration

1 month old infant

RE & LE: supertemporal perimacular chorioretinal scar with perilesional pigmentary mottling

20 day old infant

RE: optic disc hypoplasia, peripapillary nasal atrophy and excavated nasal round lesion with a hyper hyper pigmented halo, with a colobomatous-like aspect

LE: optic disc hypoplasia, peripapillary nasal atrophy, and a retinal nasal lesion with a similar pattern

Findings in infants with microcephaly & presumed Zika Virus congenital infection

DiscussionMajor health problem

Retinal lesions

Posterior pole

Optic disc

Screen infected mothers without microcephalic infants?

Limitations

1 hospital

General findings

Lack of prior research

‘Presumed Zika’

ConclusionsRetinal lesions similar to West Nile virus

Need serological tests to confirm findings

Micro = routine exam

Ophthalmologists should be aware…
