FRIDAY, Nov. 6, 2020 (HealthDay Information) — A brand new examine means that COVID-19 would not infect the attention’s cornea.
Though viruses equivalent to herpes simplex can infect the cornea and Zika has been present in corneal tissue and tears, this doesn’t look like the case with COVID-19, in accordance with researchers from Washington College College of Medication in St. Louis.
They mentioned the cornea seems to withstand an infection from the novel coronavirus.
It is not clear, nonetheless, if different tissue in and across the cornea, such because the tear ducts and the conjunctiva (free connective tissue that covers the eyeball), might be contaminated.
“Our findings don’t show that every one corneas are resistant,” mentioned first creator Dr. Jonathan Miner, an assistant professor of drugs.
“However each donor cornea we examined was immune to the novel coronavirus. It is nonetheless potential a subset of individuals could have corneas that help progress of the virus, however not one of the corneas we studied supported progress of SARS-CoV-2,” he mentioned in a college information launch.
Co-author Dr. Rajendra Apte mentioned some COVID-19 sufferers get eye symptoms equivalent to pinkeye (conjunctivitis), but it surely might be associated to secondary inflammation and never attributable to the viral an infection itself.
“The cornea and conjunctiva are identified to have receptors for the novel coronavirus, however in our research, we discovered that the virus didn’t replicate within the cornea,” mentioned Apte, a professor of ophthalmology and visible sciences. “Our information recommend that the novel coronavirus doesn’t appear to have the ability to penetrate the cornea.”
However due to unknowns that contain the tear ducts and the conjunctiva, it is too quickly to dismiss the significance of eye safety, the researchers mentioned.
“It is vital to respect what this virus is able to and take applicable precautions,” Miner mentioned. “We could be taught that eye coverings usually are not mandatory to guard in opposition to an infection within the normal neighborhood, however our research actually are only the start.”
The findings have been printed on-line Nov. 3 within the journal Cell Experiences.
