British scientists from Anglia Ruskin University (ARU) have revealed a way to detect coronavirus through the eyes: inflammation of the eyes, itching and photophobia may be indicative of COVID-19.
Itching, inflammation and light intolerance are common to other diseases, such as conjunctivitis. However, experts have concluded that eye discomfort may occur in the initial stages of infection with the coronavirus.
The three most common eye symptoms experienced by participants were photophobia (18 percent), eye pain (16 percent) and itchy eyes (17 percent). However, 81 percent reported that they experienced eye symptoms within two weeks of experiencing other COVID-19 symptoms. In 80 percent, symptoms lasted less than two weeks.
It is noted that photophobia can occur not only from exposure to bright sunlight, but also from a cell phone screen, computer and fireplace fire. Scientists have found that coronavirus eye discomfort also occurs in blind people. The reason is that there are light-sensitive cells in the retina that react to light, resulting in a burning or tingling sensation.
Previously, scientists at Washington University School of Medicine in St. Louis found a way to determine which patients with COVID-19 have a high risk of developing complications. It turned out that patients who were eventually admitted to the ICU and also had a high risk of dying quickly had high levels of mitochondrial DNA.
