Evaluation of coronavirus in tears and conjunctival secretions of patients with SARS‐CoV‐2 infection

Abstract

AbstractObjectiveThis study aimed to assess the presence of novel coronavirus in tears and conjunctival secretions of SARS–CoV‐2‐infected patients.MethodsA prospective interventional case series study was performed, and 30 confirmed novel coronavirus pneumonia (NCP) patients were selected at the First Affiliated Hospital of Zhejiang University from 26 January 2020 to 9 February 2020. At an interval of 2 to 3 days, tear and conjunctival secretions were collected twice with disposable sampling swabs for reverse‐transcription polymerase chain reaction (RT‐PCR) assay.ResultsTwenty‐one common‐type and nine severe‐type NCP patients were enrolled. Two samples of tear and conjunctival secretions were obtained from the only one patient with conjunctivitis yielded positive RT‐PCR results. Fifty‐eight samples from other patents were all negative.ConclusionWe speculate that SARS‐CoV‐2 may be detected in the tears and conjunctival secretions in NCP patients with conjunctivitis.
