126 Acquired Disc ChangesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyOptociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction. They may occur in patients following central retinal vein occlusion.
127 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.
128 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.

131 Ocular Manifestations of Systemic DisordersAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyWilson's disease (hepatolenticular degeneration) is a progressive autosomal recessive multisystem disease that may result in cirrhosis of the liver, renal dysfunction, and motor neurologic disease. A Kayser-Fleischer ring may occur as a green-brown band at the level of Descemet's membrane in the cor...
132 Isolated Congenital Optic Disc AnomaliesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis optic disc displays multiple drusen. Note the pseudopapilledema here. One can differentiate this from true papilledema in that there is no obscuration of the vessel by the peripapillary nerve fiber layer as they cross the disc margin. This photograph was taken with barrier filters in place, but...
133 Optic Disc Drusen With AutofluorescenceAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis photograph of optic disc drusen demonstrates autoflourescence with flourescein barrier filters in place. Imaging: flourescein barrier filters.
134 Orbital TumorsAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyThis 30-year-old man had a retrobulbar intraconal mass OS.

139 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...

145 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...

148 Systemic Disorders With Optic Nerve and Retinal FindingsAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyA hypercoagulable state may result from deficiency of various factors involved in the clotting pathway, such as factor V.
