301 Optic NeuropathiesRosa A. Tang, MDOptic atrophy might be a false-localizing sign of optic nerve disease, as retinal disease may secondarily produce optic atrophy. In retinitis pigmentosa, for example, patients may exhibit a waxy disc palor. Fundus imaging. Anatomy: Retina. Disease/Diagnosis: Retinitis pigmentosa; Optic atrophy.
302 Acquired Disc ChangesRosa A. Tang, MDOptociliary 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.
303 Ocular Manifestations of Systemic DisordersRosa A. Tang, MDThyroid eye disease may result in proptosis and restrictive external ophthalmoplegia. The extracoular muscles are often diffusely enlarged with sparing of the tendons.
304 Ocular Manifestations of Systemic DisordersRosa A. Tang, MDThyroid eye disease may cause proptosis and extraocular muscle enlargement that may be seen on orbital imaging studies. In general, coronal images allow the best visualization of the extraocular muscle enlargement. Pair with 94_45 and 94_46.
305 Ocular Manifestations of Systemic DisordersRosa A. Tang, MDThyroid eye disease can result in significant upper eyelid retraction and axial proptosis resulting in exposure keratopathy.
306 Isolated Congenital Optic Disc AnomaliesRosa A. Tang, MDNormally, there is no visible myelination of the nerve fiber layer in the retina. Occasionally, visible myelination occurs that takes on a characteristic white, arcuate, feathery appearance that follows the contour of the nerve fiber layer. Disease/Diagnosis: Myelinated Nerve Fiber.
307 Acquired Disc ChangesRosa A. Tang, MDAlthough optociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction, they may occur in patients with chronic open-angle glaucoma.
308 Neuro-Ophthalmic Imaging-MRIScott Forman, MDThis 23-year-old right-handed man had a history of idiopathic recurrent optic neuritis. The patient presented with acuity of 20/400 OD and 20/100 OS, with a central scotoma OD and a complete temporal defect OS. MRI with fat suppression and gadolinium revealed enhancement of the intracranial nerve an...

316 Neuro-Ophthalmic Vascular DiseaseSteven A. Newman, MDOcclusion of a branch or central retinal artery may result in acute visual loss. The ophthalmoscopic findings are retinal whitening due to ischemic retina in the distribution of the occluded artery. Sparing or selective involvement of cilioretinal artery branches may occur. Patients with a central r...
