|
Optic Neuropathies | Rosa A. Tang, MD | Optic 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 Changes | Rosa A. Tang, MD | Optociliary 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 Disorders | Rosa A. Tang, MD | Thyroid 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 Disorders | Rosa A. Tang, MD | Thyroid 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 Disorders | Rosa A. Tang, MD | Thyroid eye disease can result in significant upper eyelid retraction and axial proptosis resulting in exposure keratopathy. |
306 |
|
Isolated Congenital Optic Disc Anomalies | Rosa A. Tang, MD | Normally, 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 Changes | Rosa A. Tang, MD | Although optociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction, they may occur in patients with chronic open-angle glaucoma. |
