APICAL ORBITAL INFLAMMATION IN GIANT CELL ARTERITIS INFLAMACIÓN ORBITARIA APICAL EN ARTERITIS DE LA TEMPORAL

Case report: Our purpose is to describe a case of an acute optic neuropathy with apical muscle thickening in a patient already diagnosed with giant cell arteritis. Loss of visual acuity and perimetric concentric constriction responded rapidly to intravenous glucocorticoid therapy. There has been no relapse during continued long-term therapy with cyclophosphamide. Discussion: Giant cell arteritis is a systemic, idiopathic vasculitis; among its less frequent complications is orbital pseudotumor. Our patient required urgent treatment to avoid visual acuity loss due to compressive neuropathy and perineuritis (Arch Soc Esp Oftalmol 2007; 82: 47-50).
