Abstract
Introduction:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus causing an ongoing pandemic in 2020. Although the symptomatic patients infected by SARS-CoV-2 generally show respiratory distress, atypical manifestations such as conjunctivitis are also observed. A series of cases is reported in which reverse transcriptase polymerase chain reaction (RT-PCR) testing on tears had demonstrated the presence of the virus. However, the transmission of the virus through ocular fluids remains unknown.Case description:In this case report, the development of conjunctivitis is presented as the sole symptom of a new coronavirus disease 2019 (COVID-19) in an emergency health care worker. The patient’s first application was to the ophthalmology clinic due to redness, stinging, tearing, and photophobia for one day in the right eye. The patient had no symptoms of fever, cough, shortness of breath, or fatigue. Two days later, the RT-PCR test, blood analysis, and chest computed tomography (CT) were applied to the patient for being in contact with a COVID positive patient. Conjunctival swabs did not identify SARS-CoV-2 by RT-PCR. However, nasopharyngeal swab and blood test confirmed the diagnosis of COVID-19. Chest CT did not show pneumonia.Conclusion:This phenomenon shows that conjunctivitis may occur as a sole manifestation of COVID-19 which needs to be carefully evaluated by health care workers and eye care professionals during the pandemic.
Highlights
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus causing an ongoing pandemic in 2020
It is known that the main route of transmission of the SARS-CoV-2 is through the respiratory tract, several studies have raised concerns due to infection in the unprotected eyes (Table 1)
SARS-CoV-2 can be detected in the swab samples taken from the conjunctiva by the reverse transcriptase polymerase chain reaction (RT-PCR) method
Summary
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus causing an ongoing pandemic in 2020. SARS-CoV-2 gains entry into host cells by binding to the angiotensin-converting enzyme 2 (ACE-2) receptor, which is distributed among various tissues, including the conjunctiva.[1] During the SARS associated coronavirus outbreak of 2003, a study indicated that healthcare workers suffered from a higher risk of SARS infection when there was unprotected eye contact with secretions.[2] There are increasing reports suggesting that a few COVID19 pneumonia cases began with conjunctivitis as the initial symptom following contact with confirmed patients.
