A 38-year-old male patient presented with acute scotoma in the left eye. Color fundus photograph shows three retinal infiltrates with a triangle-shaped area of retinal ischemic whitening adjacent to a retinal infiltrate (arrow) (a). Fluorescein angiography confirms the presence of branch retinal artery occlusion corresponding to the area of retinal ischemic whitening (arrow). It also shows early hypofluorescence of the larger infiltrates and isofluorescence of the smaller infiltrate (b) and late staining of all three retinal infiltrates, retinal vascular leakage, and optic disc hyperfluorescence (c). Laboratory testing was positive for Mediterranean spotted fever (Rickettsia Conorii infection)
