In anterior optic neuropathy, optic nerve head is involved and in posterior ischemic optic neuropathy(PION) retrobulbar portion is involved. There is sudden loss of vision in both the entities but there are optic disc changes in anterior optic neuropathy while in posterior ischemic optic neuropathy optic disc is normal initially. Etiologically, posterior ischemic optic neuropathy is divided into non arteritic non-surgical, arteritic and perioperative non arteritic posterior ischemic optic neuropathy.
