Recently, a study showed that even if the COVID-19 virus in the nasal cavity of patients with COVID-19 was cleared, the virus would remain in the eyes of patients with infectious disease. Let'shear what experts say about the phenomenon that COVID-19 remains in the eyes of patients.
Why does COVID-19 remain in the eyes?
The eyes, like the nasal cavity and bronchi, have many mucous membranes, which are sensitive to viruses, so the eyes are also one of the transmission routes of COVID-19. At present, there is no specific study on the residual time of COVID-19 in the eyes, but according to the common viral conjunctivitis, the virus content in the eyes will gradually decrease after the systemic symptoms improve, which basically takes 2-3 weeks.
If there is COVID-19 in the eyes of the confirmed patient, it should be treated as viral conjunctivitis on the basis of systemic antiviral therapy. At the same time, some artificial tears can be used appropriately, because the artificial tears can play the role of diluting the virus and protect the eye surface. In addition, you must remember to wash your hands frequently and do not rub your eyes with your hands at will.
In the special period of fighting against the COVID-19 epidemic, how should we protect our eyes?
Spring is a period of high incidence of some eye diseases. For those who have a history of allergic conjunctivitis or other allergic diseases, special attention should be paid in special periods. If the eyes are dry and itchy for a long time, you must go to a doctor for examination in time. Do not rub the eyes to avoid increasing the chance of virus infection.
However, patients who have recently undergone eye surgery, especially the elderly, should try to reduce the time they go out to wear masks after surgery, because some of the gas exhaled when wearing masks will rise to the eyes, which is not conducive to eye rehabilitation.
In addition, it should be noted that some people are allergic to masks. When wearing masks, the exhaled gas will rush into the eyes, causing red and itchy eyes. If this happens, you should check your masks to ensure that they are from a regular and hygienic source. At the same time, we should reduce the number of people in crowded places and reduce the time to wear masks.
