51 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.

57 Optic NeuropathiesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyOptic disc edema with a macular star figure has been referred to as neuroretinitis.
58 Optic NeuropathiesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyOptic disc edema with a macular star figure may occur in infectious diseases (eg, cat-scratch disease, syphilis, tuberculosis, Lyme disease), inflammatory diseases (eg, sarcoid), ischemic diseases (anterior ischemic optic neuropathy), and in papilledema. Infectious causes should be sought in patient...
59 Ocular Manifestations of Systemic DisordersAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThyroid eye disease is the most common cause of unilateral or bilateral proptosis in the adult patient. Other signs of thyroid eye disease should be sought, including lid retraction, inferior scleral show, and lid lag. Patients with markedly asymmetric or strictly unilateral proptosis should probabl...

61 Motility DisturbancesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThe trochlear nerve (fourth nerve) runs from the midbrain, exits dorsally, crosses in the anterior medullary velum, enters the subarachnoid space, travels within the lateral wall of the cavernous sinus, and enters the orbit through the superior orbital fissure. A trochlear nerve palsy may be due to ...

63 Neuro-Ophthalmic Vascular DiseaseAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyCarotid cavernous fistulas (CCFs) are connections between the arterial blood flow from the carotid artery system and the cavernous sinus. CCFs may be direct high-flow fistulas or indirect low-flow fistulas. Most direct CCFs are due to trauma. Enlargement of the superior ophthalmic vein may be demons...

65 Isolated Optic Neuritis/NeuropathyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis 36-year-old man noticed blurry vision in his right eye when attempting to sight a gun. He also reported bifrontal headaches responsive to aspirin. Acuity was 20/50 OD, 20/13 OS. His right eye could be refracted to 20/20 with a +2.50 sphere.
