| Ischemic Optic Neuropathy, Arteritic | |
| When anterior ischemic optic neuropathy is secondary to an arteritic process such as temporal arteritis, the appearance of the optic disc is often distinctive. Instead of exhibiting hyperemia, the disc is noticeably pale in the acute phase. Hemorrhage is less pronounced than in non-arteritic AION, and may even be absent, as in this case. Paradoxically, the degree of nerve fiber layer opacification is less in arteritic cases, leaving the retinal vessels visible near the disc margin. | |
