Researchers studying babies with birth defects related to the Zika virus say they have discovered eye problems, not previously reported, possibly related to the virus, which could lead to severe visual impairment. With three Brazilian babies with microscopically, the researchers observed retinal damage, hemorrhage, and previously unrecognized abnormal blood vessel development related to the virus. The results are published online today in Ophthalmology, Journal of the American Academy of Ophthalmology.zika virus is now known to cause microscopically, a birth defect that is characterized by a smaller head and brain. In Brazil, the site of the most serious epidemic, almost 1.5 million people have the virus. Some 4,000 babies are newly born with microscopically, according to reports. As a result, the World Health Organization declared a public health emergency in February, adding urgency to the need for more research. An earlier study of 29 newborns in Brazil with a suspected zika congenital infection showed that a third had eye problems. This was ocular lesions, optic nerve abnormalities and corporation atrophy, a decrease of the retina and chloride, the latter of oxygen and nutrients supplied to the retina.
For this case study, researchers in ophthalmology in Brazil and Stanford University examined the eyes of three children born north of Brazil in late 2015, with microscopically. All had mothers with zika virus infections reported during the first trimester of pregnancy. Among the results, the researchers identified several types of eye problems not previously observed in relation to the zika virus, some of which could cause vision loss if left untreated. These include:
Hemorrhagic retinopathy or bleeding in the retina, the light-sensitive layer of cells lining the back of the eye;
Abnormal actualization in the retina, including signs of lack of blood vessels in the retina, where the cells can die; Y
Torpedo Naturopathy, identified by tortillas lesions in the macula, the central part of the retina.
In addition to these observations, infants in this study also had other ocular symptoms observed in the previous study. Specifically, the three infants in this case study showed signs of naturopathy, pigmented lesions that appear as pigmented spots on the macula. Four eyes had symptoms of corporation atrophy marked by the ring of dark pigmentation.
The study is small, with limited observation data. However, the results add to a growing body of clinical information on how the zika virus can affect the development and vision of children's eyes. The authors noted that it is unclear whether the viral infection itself causes ocular alterations or are a consequence of zika-induced microscopically.
"As far as I know, eye problems we found were not associated with the zika virus before.The next step is to differentiate which results are related to the zika virus itself against microscopically caused by the virus in order to better understand that babies Need screening. "
For now, the authors ask that all infants with microscopically in zika-affected areas be examined by an ophthalmologist. This is consistent with recent screening recommendations from the Centers for Disease Control and Prevention.
"Until further notice, health professionals in zika's endemic areas of infection are invited to present all children with microscopically on retinal examinations," the authors wrote. "The procedure can contribute significantly to our understanding of the infection."
