Seasonal allergy symptoms Watery or itchy eyes Nasal itching, congestion, or a runny nose Sneezing and/or post-nasal drip Itchy sinuses (nose and/or throat). CUHK Medicine study shows a higher prevalence of dry eye disease among post-COVID-19 patients. “This finding suggests the risk of tear film instability after recovery from COVID is associated with the severity of the acute infection.” See more dry eye and COVID content Reference 1. Kelvin HN Wan, assistant professor in the Department of Ophthalmology and Visual Sciences of CU Medicine, and lead author of the study, in a news release. “We found that every one-point reduction in Ct-value (inversely correlated with the viral load) from the respiratory specimen collected at hospital admission increased the risk of having any dry-eye-related ocular surface symptoms during the first month after recovery by 10%,” said Dr. March 25, 2021, 3:14 PM 4:26 May Kravitz had COVID-19 briefly but then started experiencing eye pain. Researchers reason this may be due to oxygen delivery causing gas flow to increase the evaporation of tear film. This implied a higher risk for DED when compared to post-COVID-19 participants who had not needed supplementary oxygen during hospitalization. Researchers reported that Participants who were previously treated for COVID-19 and received supplementary oxygen during hospitalization had a tear break-up time (TBUT) that was 1.6 seconds shorter than average (typically +10 seconds), researchers reported.
