178 Acquired Disc ChangesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyAlthough optociliary shunt vessels are venous collaterals that typically form in response to chronic venous obstruction, they may occur on a congenital basis as seen here.
179 Acquired Disc ChangesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyOptociliary shunt vessels are venous collaterals that form after chronic venous obstruction. The presence of optic atrophy, progressive visual loss, and optociliary shunt vessels may indicate a compressive optic nerve lesion such as meningioma.

183 Neuro-Ophthalmic Vascular DiseaseAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyArteriovenous malformations are dysplastic vascular channels. They may result in neuro-ophthalmologic findings from direct compressive effects, secondary hemorrhage, or secondary seizure disorder. CT and/or MRI may demonstrate the lesion, but cerebral arteriography is usually required to better defi...
184 Ocular Manifestations of Congenital/Inherited DiseasesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyNeurofibromatosis, type 1, is an autosomal dominant phakomatosis characterized by Lisch nodules of the iris (hamartomas) plexiform neurofibromas, café-au-lait spots on the skin, and axillary freckling. Intracranial tumors such as optic pathway gliomas may occur.
185 Ocular Manifestations of Congenital/Inherited DiseasesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyTuberous sclerosis is an autosomal dominant phakomatosis characterized by astrocytic hamartomas of the retina or optic nerve, adenoma sebaceum of the face, periungual fibromas, and astrocytic hamartomas of the brain, with secondary seizures and mental retardation

187 Ocular Disease with Retinal FindingsAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyChoroidal folds may result from choroidal tumors, compression on the eye wall from thyroid ophthalmopathy, orbital pseudotumor, orbital tumor, posterior scleritis, hypotony, scleral laceration, retinal detachment, marked hyperopia, or secondary to papilledema. Intraocular pressure measurements, refr...
188 Bridge ColobomaAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThe patient is a 35-year-old asymptomatic woman with a bridge coloboma, also known as double optic disc
189 Isolated congenital optic disc anomaliesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis image shows drusen that are especially prominent superotemporally. Pair with 92_64 and 92_67.
190 Optic disc drusen, fluorescein angiogramAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyImages 92_64 and 92_67 demonstrate the characteristics of optic disc drusen on flourescein angiography. This image shows the early arteriovenous phase, with irregular dye uptake and focal hypoflourescence superotemporally. Pair with 92_63 and 92_67
191 Optic nerve drusen, late fluorescein angiogramAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyImages 92_64 and 92_67 demonstrate the characteristics of optic disc drusen on flourescein angiography. This image displays the nodular staining of the drusen without leakage. Pair with 92_63 and 92_64.
192 Isolated congenital optic disc anomaliesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis is a photograph of peripheral drusen. The paired image 92_69 demonstrates the typical autofluorescence.
193 Optic disc drusen autofluorescenceAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis case of optic disc drusen demonstrates the typical autofluorescence. Pair with 92_68.
194 Congenitally Tilted Optic DiscAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyColobomas or defects of the optic nerve may exhibit spontaneous pulsations.
195 Ocular Manifestations of Congenital/Inherited DiseasesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyImage shows a patient with the Laurence-Moon-Biedl syndrome, an autosomal recessive syndrome characterized by obesity, mental retardation, retinitis pigmentosa (see Image 91_07), polydactyly, and hypogonadism. Pair with 91_07.
196 Neuro-Ophthalmic Consequences of TherapyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology Societyradiation retinopathy may mimic diabetic or hypertensive optic neuropathy. A history of irradiation to the eye, orbit, or head is mandatory. Radiation retinopathy usually occurs many months after radiation therapy.
197 Isolated Optic Neuritis/NeuropathyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyPapilledema may produce visual loss due to chronic atrophic papilledema, secondary macular hemorrhage, exudate or edema, secondary ischemic optic neuropathy, or secondary subretinal neovascular membrane formation. Patients with papilledema and visual loss should be suspected of harboring one of thes...
198 Isolated Optic Neuritis/NeuropathyAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyPapilledema may produce visual loss due to chronic atrophic papilledema, secondary macular hemorrhage, exudate or edema, secondary ischemic optic neuropathy, or secondary subretinal neovascular membrane formation.

199 Neuro-Ophthalmic Vascular DiseaseAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyAneurysms of the intracranial circulation may act as mass lesions and compress the afferent of efferent visual pathway. Ophthalmic artery aneurysms may compress the optic nerve and result in an optic neuropathy (ie, visual loss, afferent pupillary defect, optic atrophy). Treatment includes endovascu...
