Sore eyes are probably the most important vision-based indicator of COVID-19, based on a research led by an Indian-origin scientist which offers extra understanding of how the novel coronavirus travels by the physique.
Researchers at Anglia Ruskin College (ARU) within the UK requested individuals who had a confirmed COVID-19 analysis to finish a questionnaire about their signs, and the way these in comparison with earlier than they examined constructive.
“This is the first study to investigate the various eye symptoms indicative of conjunctivitis in relation to COVID-19, their time frame in relation to other well-known COVID-19 symptoms and their duration,” mentioned research lead creator Professor Shahina Pardhan, Director of the Imaginative and prescient and Eye Analysis Institute at ARU.
The research, revealed within the journal BMJ Open Ophthalmology, discovered that sore eyes was considerably extra frequent when the members had COVID-19, with 16 per cent reporting the difficulty as one in every of their signs.
Simply 5 per cent of the members reported having had the situation beforehand, the researchers mentioned.
Whereas 18 per cent of individuals reported affected by photophobia or mild sensitivity as one in every of their signs, this was solely a 5 per cent enhance from their pre-COVID-19 state, they mentioned.
The research discovered that of the 83 respondents, 81 per cent reported ocular points inside two weeks of different COVID-19 signs, and of these, 80 per cent reported their eye issues lasted lower than two weeks.
The most typical reported signs general had been fatigue — suffered by 90 per cent of respondents — a fever seen 76 per cent and a dry cough which was reported by 66 per cent.
“While it is important that ocular symptoms are included in the list of possible COVID-19 symptoms, we argue that sore eyes should replace ‘conjunctivitis’ as it is important to differentiate from symptoms of other types of infections, such as bacterial infections, which manifest as mucous discharge or gritty eyes,” Pardhan mentioned.
“This study is important because it helps us understand more about how COVID-19 can infect the conjunctiva and how this then allows the virus to spread through the body,” she added.
