1 Isolated congenital optic disc anomaliesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyPatients with midline closure defects may exhibit abnormalities in the optic nerve, choroid, retinal pigment epithelium or retina. Anterior closure defects may result in colobomas of the structures of the anterior segment, such as the iris.
2 Pupillary SyndromeAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyIntermittent dilation of the pupils may occur as a benign phenomenon in healthy young adults. In the absence of other third nerve signs, (eg, ptosis, diplopia, ophthalmoplegia), an isolated transient dilation of the pupil in an otherwise healthy adult is unlikely to represent a third nerve palsy. Tr...

4 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 ...

11 Neuro-Ophthalmic Imaging-Cerebral AngiographyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyEhlers-Danlos syndrome is a connective tissue disorder that may affect blood vessels and predispose some affected patients to development of carotid cavernous fistula. Most patients with high-flow direct carotid cavernous sinus fistulas have suffered acute traumatic tears in the internal carotid art...
12 Motility DisturbancesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis 5-year-old child presented with a 70 PD exotropia OS and a right face turn. She had a CT scan of the head at age 4 months that was normal , and she was felt to have an isolated left medial rectus paresis. Her acuity was 20/20 OU. She could fuse with a large face turn, and was orthomorphic is ex...
