Abstract

Purpose: To describe two cases of retinal artery occlusion followed by contralateral amaurosis fugax associated with eosinophilic granulomatosis with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome). Observations: Case 1 is a 57 year-old male who presented with transient vision loss in the right eye two weeks after a cilioretinal artery occlusion in the left eye. Evaluation eventually led to a diagnosis of EGPA. The patient was treated with high-dose steroids followed by systemic immunomodulatory therapy. Vision in the right eye recovered to 20/20 with no further episodes of vision loss. Case 2 is a 55 year-old male with a known diagnosis of EGPA who presented with transient vision loss in the right eye four weeks after a central retinal artery occlusion of the left eye. This patient also successfully recovered vision in the right eye after treatment with high-dose steroids following a change in his systemic immunomodulatory therapy. Conclusions and Importance: While ANCA-vasculitides are an uncommon cause of retinal artery occlusion and amaurosis fugax, it is important that they remain in the differential diagnosis, as good visual outcomes can be achieved with prompt initiation of appropriate therapies.
