      2. High dose Corticosteroids immediately (do not wait for temporal artery biopsy)
        1. Prednisone 2 mg/kg/day or Methylprednisolone 250 mg every 6 hours IV
        2. Goal is to preserve other, healthy eye
    3. Non-arteritic Ischemic Optic neuropathy
      1. Corticosteroids are also indicated immediately

Optic Neuropathy, Ischemic (C0155305)

Definition (MSHCZE) Onemocnění s ischemií přední části papily zrakového nervu způsobené okluzí ciliárních tepen. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (MSH) Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.
