People on ventilators often develop a type of eye irritation called chemosis, a swelling or bulging of the eye membranes and eyelids, Patel says. Other ocular symptoms can include dry eyes, redness, itching, blurry vision, sensitivity to light and the feeling that there is a foreign particle in the eye. This condition affected nearly 89 percent of people with eye symptoms, researchers in Iran reported in a 2021 meta-analysis that included 8,219 COVID patients across 38 studies. The most common symptom is conjunctivitis, or inflammation of the eye lining. Over the pandemic’s first year and a half, accumulated data have established that about 11 percent of people with COVID develop some kind of eye issue, according to a review of multiple studies. But because COVID causes severe respiratory problems and other symptoms, and because most eye doctors closed their offices during lockdowns, eyes were overlooked at first, Patel says. And in Toronto, the risk of infection was higher among health care workers who did not wear eye protection. During the 2003 SARS outbreak, researchers in Singapore detected the virus that causes that disease in patients’ tears. From the beginning of the pandemic, reports included red eyes as a common symptom. Li died from his illness early in 2020, but his case was not the only early clue that eyes might play a role in the virus’s spread. Moran Eye Center, who co-authored a 2021 review of research on COVID’s ocular symptoms. He likely caught the virus from an asymptomatic glaucoma patient, according to Bhupendra Patel, of the University of Utah’s John A. One of the first people who tried to warn the world about COVID was Li Wenliang, a Chinese ophthalmologist in Wuhan. “The data are growing to suggest that there are more neural consequences of this infection than we originally thought,” says Lee Gehrke, a molecular biologist at the Massachusetts Institute of Technology. Nearly two years into the pandemic, research on COVID’s effects on the eyes and ears suggests that scientists have much more to learn about how the virus affects our bodies and nervous systems, experts say. Instead of just a fever, cough or changes in taste and smell, the first signs of illness might include irritated eyes, hearing problems or balance issues. As researchers work to understand how the virus infiltrates our senses, their findings suggest that people may need to broaden the scope of warning signs for when to get tested. More than 10 percent of people who get COVID develop some type of eye or ear symptom, according to the latest data, and both categories are among the complaints that can end up persisting for a long time. Red eyes, ringing ears, sensitivity to light, trouble hearing: although a loss of taste and smell have become well-known sensory symptoms of COVID, accumulating research suggests that vision and hearing are also frequent targets of SARS-COV-2, the virus that causes the disease. ![]()
