What Researchers Did
Researchers described a rare case of multiple branch retinal arteriolar occlusions and encephalopathy in a 53-year-old man 10 days after smallpox vaccination.
What They Found
The patient presented with sudden temporal visual field loss in his left eye, with examination revealing decreased visual acuity and a retinal infarct. Fluorescein angiography showed delayed arterial filling and multiple non-perfused areas, while brain MRI disclosed white matter focal lesions. Following treatment with methylprednisolone and immunoglobulins, his visual acuity improved and visual field was substantially restored at a 3-month follow-up.
Canadian Relevance
This case report describes a patient outside of Canada, therefore it has no direct Canadian relevance.
Study Limitations
As a single case report, this study's findings are not generalizable to the broader population and cannot establish causality.
