Purpose: To report a case of multiple superior quadrant intraretinal haemorrhages in post-COVID-19 patient.
Case description: A 58-year-old male with a history of coronary artery disease and hypertension, presented with multiple superior quadrant intraretinal haemorrhages in the superonasal quadrant of the left eye 1 month after hospitalization for COVID-19. The right eye was normal. During his 10-day stay, he was treated with hydroxychloroquine, lopinavir + ritonavir, ceftriaxone, and his pre-existing antiplatelet therapy. During hospitalization, a complete medical work up showed an anomalous increase in D-dimer. He did not require intensive care support.
Conclusions: In this report, we focused on the origin of retinal bleeding in a post COVID-19 patient, likely due to a focal occlusion of a vessel. Considering the nature of SARS-CoV-2 infection, we hypothesize that retinal haemorrhages were caused by a combination of factors including the patient's antiplatelet therapy and the thrombotic microvascular injury caused by the virus.
