Zika virus may persist in the eyes

According to a study it's said that zika virus is capable of infecting the eye. The study in mice helps in explaining the answers all the questions put forward related to it. Researchers have found that Zika virus can live in eyes and have identified genetic material from the virus in tears.The study explains how the patients affected by this develop eye disease which also includes a condition known as uveitis which may leads to permanent vision loss.The study on Cell Reports explains the effects of virus infection in eyes of mouse fetuses,newborns and adults. The upcoming researchers are now planning complementary studies in human patients infected with virus.Its just said that eye is like a reservoir for Zika virus. This cause mild disease in adults may also leads to Brain damage and death
fetuses. About third of all babies infected in utero with Zika shows eye disease such as inflammation of the optic nerve, retinal damage or blindness after birth. In adults it causes redness and richness in eyes and in some rare cases uveitis.To see the effects the researchers infected an adult mice and found the live virus in eyes a week later.This confirms that virus can travel to eye but still not confirmed that whether it's crossing the blood retina.Even the people could acquire zika infection through contact with the tears from infected people. It's found that infected mice's tears contained Zika RNA.
