Ischemic Ocular Involvement in Eosinophilic Granulomatosis with Polyangiitis: A Case Report.

To report an uncommon, ocular ischemic involvement in a patient diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). Case report. A 77-year-old male exhibited headaches, scotomas and decreased visual acuity. The temporal artery biopsy revealed necrotizing vasculitis with eosinophilic infiltration. The patient responded to corticosteroid therapy, and no relapses were observed after 24 months of follow-up. This case highlights the importance of differentiating EGPA from other ischemic ocular conditions like giant cell arteritis. Temporal artery biopsy remains an essential diagnostic tool in these complex cases, and further guidelines are needed to manage ischemic manifestations in EGPA patients.
