2-53b - Venous Pulsations | On the disc, look for spontaneous venous pulsations. Spontaneous venous pulsations can be seen in the large trunks of veins at the level of the disc margin. They are normally present and seen in 37-90% of normals -- depending on the experience of the examiner and the shape of the disc. The spontaneo... | Image |

2-7a - Disc Anatomy | The optic disc appearance is determined by: the size of the eye, the size of the scleral canal, how the nerve is inserted into the globe, the appearance of the lamina cribrosa, where myelination stops, and what is left behind in normal development. Even though this is a disc with a very large cup, i... | Image |

3-59a - Glioma | This 45-year-old man presented with vision loss in his right eye; his examination showed severe disc swelling in this eye and vision loss on visual field testing (3-59a). MRI with fat saturation and enhancement and MRI with T2 signals also confirm an enlarged optic nerve. (3-59c) Excisional biopsy o... | Image |

3-60a - Meningioma | This 35 year old woman presented with slowly progressive loss of central acuity to 20/30. 3-60a: Her visual field shows progressive restriction over time. 3-60b: Her disc was chronically swollen, with refractile bodies on the disc surface. 3-60d: The CT axial scan showed an enlarged calcified optic... | Image |

3-64a - Shunt Vessels (CRVO) | This man with a chronic CRVO and retino-choroidal collaterals developed AION and his collaterals disappeared. CRVO with retinochoroidal collaterals is almost always associated with multiple peripheral dot and blot hemorrhages as well as nerve fiber layer infarcts of various ages. Notice the retino-c... | Image |

3-66a - Shunt Vessels (Post-papilledema) | The retino-choroidal collaterals seen with chronic papilledema begin with a "Hairnet" of telangiectasias that gradually winnow down to one or more large collateral tortuous draining channel. The presence of these vessels is evidence of long standing disc swelling. When the CSF pressure is lowered, t... | Image |

4-35 - Cupped Optic Nerve | Atrophic Glaucoma Atrophic glaucomatous discs show thinning of the neuro-retinal rim, "saucerization" (which is shallow cupping), evidence of peripapillary atrophy, and pallor of the very narrow neuroretinal rim. Notice that there is severe atrophy of the nerve fiber layer. | Image |

4-52b - Dominant Optic Neuropathy | A son presented with bilateral optic atrophy of unknown etiology after he failed a school visual exam. When looking for dominant optic atrophy, look at the parents. Mother was examined to find similar kind of atrophy. 4-52a mother, 4-52b son. | Image |

Shunt Vessel Meningioma | RETINO-CHOROIDAL (OPTO-CILIARY) COLLATERAL VESSELS: (also known as Retinal-choroidal venous collaterals, opticociliary veins or ciliary shunt vessels) Retino-choroidal collaterals are potential telangiectatic connections between the retina and choroidal circulation. Although sometimes called "shunts... | Image |

Shunt Vessel Meningioma - MRI | Meningiomas block venous egress and open potential venous channels known as retinochoroidal (optociliary) collateral vein. This meningioma extends from the back of the globe through the optic canal. | Image |
