A new COVID-19 symptom: reddened eyes can be confused with conjunctivitis

A new COVID-19 symptom: reddened eyes

The ophthalmologists from the University of Alberta concluded that COVID-19 was manifested in a completely new syndrome that doctors had not previously observed. That is conjunctivitis that manifests itself in redness of the eyes. The experts say that this symptom should be considered as a sign of a possible infection, and doctors, before prescribing treatment to the patients, must first send them to take a coronavirus test, while observing all safety precautions.

Common and well-known symptoms of the coronavirus are cough, fever, shortness of breath, and recently, the scientists have found out that conjunctivitis and keratoconjunctivitis can also be primary symptoms.


In March, a 29-year-old patient, who was diagnosed with severe conjunctivitis and minimal respiratory symptoms, was admitted to a hospital in Alberta. The woman underwent a course of treatment and she felt much better. She reported that she returned from Asia. The patient was prescribed a test for COVID-19 and it turned out to be positive.

Carlos Solarte, an associate professor of the Department of Ophthalmology, noted that in the case of the eye disease in the case of the coronavirus it turned out to be the main symptom, the woman had no other manifestations of the virus. The lungs were clean and healthy.

The scientists conducted a study and found that from the very beginning of the epidemic, conjunctivitis was identified as a secondary symptom. It appeared in about 10-15% of the COVID-19 cases. From that moment, the researchers made every effort to find out how the virus can penetrate the body through the mucous membranes and act on them.


As a result, conjunctivitis and keratoconjunctivitis are now recognized as possible main symptoms of COVID-19. In the very first case, the patient recovered without any problems and complications.

But doctors and other specialists, her relatives and neighbors were in contact with her, they should have been in quarantine, but it did not happen. When all these people were examined, it turned out that not one had a positive reaction with the coronavirus test.
