Central retinal artery occlusion in an ANCA negative Churg-Strauss syndrome patient

To describe a central retinal artery occlusion in a patient with antineutrophil cytoplasmic antibody (ANCA) negative Churg-Strauss syndrome. Review of clinical and laboratory findings of a 44-year-old woman with ANCA negative Churg-Strauss syndrome that developed sudden vision loss in left eye. Left central retinal artery occlusion was diagnosed by retinal whitening, a cherry-red spot, and delayed arterial filling on fluorescein angiography. Perinuclear ANCA and cytoplasmic ANCA were negative. Central retinal artery occlusion can occur in ANCA negative Churg-Strauss syndrome. Patients with this diagnosis should be considered for prophylactic high dose corticosteroid, regardless of their ANCA status.
