1 Acquired Disc ChangesAAO/NANOS - American Academy of Ophthalmology / North American Neuro-Ophthalmology SocietyAlthough optociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction, they may occur in patients with chronic open-angle glaucoma.
2 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.
3 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.
4 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.
