Ocular abnormalities were present in approximately 33% of patients with COVID-19, according to a case series published in JAMA Ophthalmology.
In this study, researchers retrospectively reviewed ocular manifestations and blood tests results and reverse transcriptase–polymerase chain reaction (RT-PCR) from nasopharyngeal and conjunctival swabs from 38 patients with COVID-19 treated in Hubei province (mean (SD) age: 65.8 (16.6) years).
Approximately 32% of patients had ocular manifestations such as conjunctival hyperemia, chemosis, epiphora, or increased secretions. These patients were more likely to have a severe form of COVID-19.
Of the patients with ocular abnormalities, approximately 92% had positive results for SARS-CoV-2 on RT-PCR from nasopharyngeal swabs and 16.7% had positive conjunctival and nasopharyngeal swabs.
"These data may assist ophthalmologists and others to understand the ocular manifestations of COVID-19, thus enhancing the diagnosis and prevention of the transmission of the disease," the authors wrote.
