The Frequency of Hand-to-Eye/Nose Contact can Increase the Risk of Ocular Symptoms in SARS-CoV-2-Infected Patients
Abstract PurposeSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has the capacity to use the eye for transocular entry. The characteristics of lacrimal drainage remind us to pay attention to the transmission route passing through the nasolacrimal ducts and then into the respiratory tract. The aim of this study was to assess ocular symptoms and hand-to-eye/nose contact behaviour in SARS-CoV-2-infected patients. MethodsA questionnaire was designed by brain storing method according to practical requirements, then the survey of ocular symptoms and hand-to-eye/nose contact behaviour in SARS-CoV-2-infected patients was administered in person. The patients answered the items under the guidance of a nurse. The data of ocular symptoms and basic information was collected analysed. The correlation between ocular symptoms and hand-to-eye/nose contact behaviour was evaluated.Results The most common ocular symptoms were increased discharge (in 53.19% of patients), foreign body sensation (44.68%), tearing (44.68%), conjunctival congestion (40.43%) and mild eye pain (40.43%). In total, 61.7% of patients had nasal obstruction and running. A total of 40.4% of patients blew their nose more frequently than usual because of nasal symptoms. A total of 63.8% of patients rubbed their eyes with their hands 1-5 times per day. Only 44.68% of patients washed their hands immediately when arriving at home more than 6 days per week. Increased frequencies of blowing noses (p=0.032), washing hands (p=0.025), and rubbing eyes (p=0.005) can affect ocular symptoms. The frequency and the way of face washing had no correlation with ocular symptoms.ConclusionsOcular symptoms in SARS-CoV-2-infected patients are much more common than currently reported but nonspecific. This prompt us pay more attention to the true incidence of conjunctivitis in SARS-CoV-2-infected patients. The frequency of hand-to-eye/nose contact can increase the risk of presenting ocular symptoms. However, hand washing can decrease the risk. These results provide direct evidence of behaviour change and smooth the concerns for many people.
