New York, May 25: A team of ophthalmologists has found previously unreported eye problems in infants born to mothers who showed signs of Zika virus infection during pregncy. The researchers from Brazil and Stanford University observed unreported eye problems like retil lesions, haemorrhaging and abnormal blood vessel development in three Brazilian infants with microcephaly — a birth defect marked by smaller head and brain size caused by Zika virus. Besides these observations, the infants in this study — published in the jourl Ophthalmology — also exhibited other ocular symptoms noted in a previous study. Specifically, all three babies in this case study showed signs of pigmentary maculopathy — lesions that appear as speckles of pigment on the macula. Four eyes had symptoms of chorioretil atrophy marked by a darkly pigmented ring. (IANS)
