Abstract Objectives We compared the laboratory and clinical symptoms of coronavirus disease 2019 (COVID-19), other viral (beside COVID-19), and bacterial conjunctivitis patients with the values of controls. Methods Twenty COVID-19, 15 other viral, 15 bacterial patients, and 15 control group were included in the study. COVID-19 was diagnosed with the real time reverse transcription–polymerase chain reaction while the indirect immunofluorescent antibody test was used in the detection of other viral agents. Bacterial agents were determined with the detection of the agent. The ophthalmologic examination of all cases was carried out by direct penlight, and the anterior segment evaluation was performed. The laboratory findings of all cases included in the study were obtained from the hospital records. Results It was determined that 5% conjunctivitis and 5% diplopia developed in patients diagnosed with COVID-19, 20% conjunctivitis developed in patients due to other viral agents, and 66.6% conjunctivitis developed in patients due to bacterial agents. Conclusion The incidence of conjunctivitis in COVID-19 patients was lower than in other viral and bacterial groups. Neutrophil/lymphocyte ratio and C-reactive protein come to the forefront as precious parameters with high specificity and sensitivity that might be useful to distinguish these diseases.
