A 72-year-old male patient was referred to our outpatient clinic with a painful left eye protrusion accompanied by marked conjunctival chemosis and
external ophthalmoplegia being progressed despite topical and oral
antibiotic therapy. He developed ocular symptoms 9 days after receiving his second
SARS-CoV-2 vaccine (VeroCell). Of note, in previous history, 2 weeks after the first dose of the
COVID-19 vaccine, he also developed a life-threatening laryngeal oedema treated at an emergency care unit. MRI of the orbit excluded pansinusitis as possible origin of the
orbital cellulitis, and repeated
COVID-19 antigen and antibody PCR tests were negative during his hospitalization. On the next day after his admittance, parenteral
dexamethasone 250 mg/die treatment was commenced resulting in a quick and complete resolution of the symptoms. Due to the facts regarding this case, such as the temporal coincidence and the lack of respective comorbidity, there might be a causative relationship between the vaccination and the presented
orbital cellulitis. To the best of our knowledge, this is the first report on
orbital cellulitis as a possible ocular adverse event following
COVID-19 vaccination.
