Purpose To investigate the relationship between laboratory blood parameters and ocular findings in hospitalized moderate or severe COVID-19 patients. Methods Ophthalmologic examination of 215 patients who were hospitalized with the diagnosis of COVID-19 was performed in their beds and their ocular findings were noted. Blood parameters were compared in patients with and without conjunctivitis like symptoms. Results Conjunctivitis like inflammatory findings were detected in 15 (7.44%) of 215 moderate or severe COVID-19 patients. There was no difference between the patients with and without ocular findings in terms of laboratory findings such as WBCs, neutrophil counts, lymphocyte counts, NLR, LDH, procalcitonin, D-dimer, CRP, and ferritin. Conclusion There was a significant relationship between COVID-19 and an acute conjunctival inflammatory response. Blood parameters that determined progression in patients with COVID-19 were not significant in terms of ocular findings.
