Table showing comparison of tear samples and nasopharyngeal swab samples over the course of coronavirus disease 2019 (COVID-19) illness. Cycle threshold results of all nasopharyngeal swabs are displayed. All tear samples showed negative results on both viral isolation and reverse-transcription polymer chain reaction analysis. These results are labelled by a red box.
