SARS-CoV-2 can not penetrate eyes cornea, study finds | Corona virus cannot enter eye cornea, latest study reveals

Mumbai: A new study by researchers at Washington University School of Medicine has revealed that the cornea in the eye resists infection with the corona virus (SARS-Cov-2). Other viruses such as simplex and zika virus affect the cornea, while the corona virus is unable to replicate itself here. According to the findings published in the journal Cell Report, researchers are yet to find out whether the cornea and other tissues around it remain unaffected.

Not all corneas are resistant
Jonathan J Minor, the author of the report, said, ‘Our findings do not prove that all corneas are resistant, but every donor cornea we examined was resistant to the corona virus. It is still possible that a group of people may have a cornea that helps the virus grow, but none of those we studied were going to help SARS-CoV-2 grow. ‘

Symptoms visible in some patients’ eyes
Rajendra S. Apte, professor in the Department of Ophthalmology and Ophthalmology at John F. Hardness, said, ‘Some Kovid-19 patients get eye symptoms, such as conjunctivitis (pink eye), but it is unclear whether viral infection is the cause. There can be other reasons for this. He said, ‘The cornea and conjunctiva are known as receptors of the corona virus, but in our studies we found that the virus did not replicate in the cornea.’

Study is in the initial stage
Researchers also discovered key substances in corneal tissue, which may stimulate or inhibit the growth of the virus. In conclusion, the authors said, ‘Actually our study is still in the beginning. We need more clinical studies to better understand all possible routes of SARS-CoV-2 transmission including the eye. ‘
