Accordingly, the IL-1β tear film concentration was found to be higher in patients with pneumonia complicating COVID-19 (median [IQR] = 0.52 [0.96] pg/ml for patients with pneumonia vs 0.28 [0.29] pg/ml for patients without pneumonia; p = 0.0041). The gene discussed is IL1B; the disease is susceptibility to pneumonia measurement.
