FRIDAY, November 6, 2020 (HealthDay News) – A new study found COVID-19 does not cause corneal infections of the eye.
Although viruses like herpes simplex can infect the cornea and Zika has been found in corneal tissue and tears, this does not appear to be true for COVID-19, according to researchers from the College of Medicine. study Washington in St. Petersburg
The cornea seems to be able to fight infection from the new coronavirus, they said.
However, it is not clear if other tissues in and around the cornea, such as the tear duct and conjunctiva (the loose connective tissue covering the eyeball), could become infected.
“Our findings do not prove that all corneas are resistant to drugs,”; said the first author, Dr Jonathan Miner, an assistant professor of medicine.
“But every donor cornea we have tested is resistant to the new coronavirus,” he said. “There may be a small number of people whose cornea supports viral growth, but none of them are. Which cornea we studied supports the development of SARS-CoV-2 “. in a university newsletter.
Co-author Dr Rajendra Apte said that some patients with COVID-19 have eye symptoms such as red eye pain (conjunctivitis), but it may be related to secondary inflammation, rather than the infected body.
“The cornea and conjunctiva are known to have receptors for the new coronavirus, but in our studies we found that this virus,” said Apte, professor of ophthalmology and visual sciences. does not multiply in the cornea ”. “Our data shows that the new coronavirus doesn’t seem to be able to penetrate the cornea.”
But because of the unknowns involving tear duct and conjunctiva, it is too early to rule out the importance of eye protection, the researchers said.
“It is important to respect the capabilities of the virus and take the appropriate precautions,” Miner said. “We may know that blindness is not needed to protect against infection in the general community, but our studies are really just the beginning.”
The findings were published online November 3 in the journal Mobile Reporting.
