Study summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified, highly contagious RNA virus causing respiratory infectious disease, Coronavirus Disease 2019 (COVID-19). Conjunctivitis has been reported as a rare finding of the disease, and preliminary studies showed that the virus RNA could be detected in ocular secretions using polymerase chain reaction (PCR) assays when conjunctivitis present. This study aims to estimate the proportion of SARS-CoV-2 associated conjunctivitis among patients with suspected viral conjunctivitis presented to the ophthalmology clinics of Wilmer Eye Institute during the COVID-19 pandemic. The investigators also aim to identify whether SARS-CoV-2 associated conjunctivitis is an isolated finding or an early sign of COVID-19.

What researchers measure

Primary outcomes

  1. Proportion of conjunctival samples tested positive for SARS-CoV-2

    Number of conjunctival samples with positive PCR divided by the total number of conjunctival samples

    Time frame: 1 year

Secondary outcomes

  1. Proportion of nasal samples tested positive for SARS-CoV-2 among patients with positive conjunctival samples

    Number of nasal samples with positive PCR divided by the number of conjunctival samples with positive PCR

    Time frame: 1 year

  2. Proportion of nasopharyngeal samples tested positive for SARS-CoV-2 among patients with positive conjunctival samples

    Number of nasopharyngeal samples with positive PCR divided by the number of conjunctival samples with positive PCR

    Time frame: 1 year

  3. Rate of development of COVID-19 in the study patient population

    Number of patients developed COVID-19 divided by the number of the study population

    Time frame: 1 year

  4. Positive conjunctival sample rate in patient developed COVID-19

    Number of conjunctival samples with positive PCR divided by the number of patients developed COVID-19

    Time frame: 1 year
