Arteritic ischemic optic neuropathy occurs in the setting of giant cell arteritis and often produces devastating irreversible vision loss. It is a medical emergency because there is a high risk of fellow eye involvement if high-dose corticosteroid treatment is not initiated in a timely fashion. In this chapter, we begin by reviewing the clinical features of anterior and posterior ischemic optic neuropathy. We next review the clinical features of arteritic ischemic optic neuropathy. We then discuss the clinical features and workup for giant cell arteritis. Lastly, we review the initial and long-term management approach for ischemic optic neuropathy occuring in the setting of giant cell arteritis.
