151 Isolated Optic Neuritis/NeuropathyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyPapilledema usually results in bilateral optic disc edema without visual loss. The blind spot may enlarge initially, but progressive visual field loss may occur with chronic optic disc edema. Asymmetric or frankly unilateral optic disc edema may occur due to structural disc fractures that prevent th...

156 Isolated Optic Neuritis/NeuropathyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietySeveral Primary Mutations result in Leber's hereditary optic neuropathy, including mitochondrial deletions at positions 11778, 3460, and 14484. Although the 11778 is the most common mutation, the 11484 has the best prognosis for spontaneous recovery. This case exhibits the 3460 mutation.

172 Neuro-Ophthalmic Imaging-MRIAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyAxial view of Arnold-Chiari malformation on a patient with downbeat nystagmus. Note the presence of the cerebellar tonsils posterior to the caudal medulla. In addition to downbeat nystagmus, Arnold-Chiari malformations can sometimes lead to increased intracranial pressure and papilledema.
