A 15-year-old African-American boy presented with unilateral decrease in vision following an episode of myopericarditis. His ocular examination was significant for diffuse retinal oedema and intraretinal haemorrhages. He was diagnosed with a central retinal vein occlusion and was referred to rheumatology for further evaluation following negative hypercoaguable studies. He was later found to have systemic lupus erythematous. Approximately 8 months after presentation, the patient's vision improved and remained stable at 20/40.
