Ocular Features and Associated Systemic Findings in SARS-CoV-2 Infection.Ocul Immunol Inflamm. 2020 Aug 17; 28(6):916-921.OI
To describe the prevalence of ocular features among COVID-19 patients and their relationship with clinical data, inflammatory markers and respiratory support therapy (including CPAP); to investigate SARS-CoV-2 in ocular secretions of symptomatic patients.
172 COVID-19 patients were evaluated for presence of ocular manifestations. Clinical and laboratory data were also reviewed. Conjunctival swabs were analyzed for SARS-CoV-2 by RT-PCR.
Forty-five patients (26.2%) reported ocular manifestations. Patients treated with CPAP were more likely to have ocular abnormalities (p <.01). The presence of ocular symptoms was not associated with more significant alterations on blood tests. Conjunctival swabs from patients with suspect conjunctivitis yielded negative results for SARS-CoV-2.
Ocular features are not infrequent in COVID-19 patients, but the presence of SARS-CoV-2 in ocular secretions is low. Ocular manifestations in hospitalized COVID-19 patients can also be a consequence of respiratory support therapy. Prevention of possible transmission through ocular secretions is still recommended.
