Researchers with a clear message
Corona infection can lead to eye problems
Have you ever had Corona? Then, according to American researchers, you should be examined by an ophthalmologist.

How many times have you been infected with coronavirus in the past?
In fact, this question is almost irrelevant, because even those who have tested positive only once should take care of their eyes: a new study suggests that Covid-19 can cause long-term damage to the optic nerve. What exactly did the researchers find? We clarify.

What is the connection between eye sight and corona infection?
Pawan Kumar Singh, Assistant Professor of Ophthalmology, said at the end of a study: All those infected with Corona should be examined by an ophthalmologist.
This applies to anyone without symptoms of Covid-19. No matter how long ago the infection occurred, according to the doctor, the damage to the eye may have resulted.

Study: Mouse test shows coronaviruses can be detected in animal retinas
What exactly did researchers at the Missouri School of Medicine discover?
When testing for coronavirus in mice, the animals inhale the coronavirus through their noses and mouths. A few hours later, the scientists noticed that the viruses were also detected in the retinas of the mice.

SARS-CoV-2 is able to break the sensory barrier in the retina.
Corona Viruses Can Break the Blood-Retinal Barrier!
This barrier on the retina is actually designed to protect the eye from infection. Prophylaxis usually prevents pathogens from reaching the retina.
If this is exceeded, it can cause inflammatory reactions in the eye, which in worst cases can lead to complete loss of vision.

Researchers with a clear message: “We recommend a visit to an ophthalmologist”
Until now, scientists thought that corona infection could lead to eye damage, especially if the virus comes into direct contact with the surface of the eyes due to the high viral load in the air.
What’s interesting about the new results is that coronaviruses can enter the eyes in other ways as well.
When viruses previously entered the body through the mouth or nose. Against this background, research leader Singh concluded that everyone infected with the coronavirus should “look for signs of pathological changes in the retina” at least once. (mjä)
