PURPOSE: Coronavirus Disease 2019 (COVID-19) pneumonia may predispose to thromboembolic disease, including after the acute phase. We report on a unique case of central retinal vein occlusion (CRVO) occurring eight months after diagnosis of Coronavirus Disease 2019 (COVID-19) pneumonia in a likely case of post-COVID-19 syndrome. CASE REPORT: A 42-year-old man developed blurred vision in his right eye eight months after symptoms of pneumonia. He had no underlying medical conditions, but experienced exertional chest pain since diagnosis of COVID-19 was confirmed by detection of SARS-CoV-2 on nasopharyngeal swab and was also seeing cardiology for management of myocarditis. His best-corrected visual acuity on snellen chart testing was reduced to 6/18 in the affected right eye, and dilated fundal examination revealed a non-ischaemic CRVO. CONCLUSION: The thromboembolic complications of COVID-19 may extend to CRVO, which in this case presented months after onset of symptoms of pneumonia, in association with myocarditis.
