| 1 |  | 3-33b - Papilledema Stages | Grading Papilledema: Stage 2 = Elevation of the disc margin 360 degrees. Since the blood vessels at the disc margin are not swollen or obscured, this disc could be mistaken for pseudo-papilledema. | Image |
| 2 |  | Bilateral Iris Colobomas | Coloboma literally means a "gap"-and can be used to describe any fissure, hole, or gap in the eye. The term most often is used to refer to a congenital gap in the disc, retina, the choroid, and the iris. Colobomas occur because the embryonic fissure fails to fuse. Since the fissure closure begins in... | Image |
| 3 |  | 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 |
| 4 |  | 3-59c - 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 |
| 5 |  | Notching of the Neuro-retinal Rim | The neuro-retinal rim becomes thinner; in particular the rim superotemporally and inferortemporally may develop a notch which is usually superior or inferior and rarely nasal or temporal. These notches are believed to be due to focal ischemic damage to the neuro-retinal rim. Glaucoma with Notching a... | Image |
| 6 |  | 2-4a - 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 |
| 7 |  | 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 |
| 8 |  | 3-65 - Shunt Vessels (Glaucoma) | Chronic end-stage glaucoma produces high pressure that interferes with venous drainage from the disc and broad smooth venous collaterals drain the disc centrifugally to the disc margin where they drain. | Image |
| 9 |  | 2-6a - Little Red Discs | | Image |
| 10 |  | 2-6b - Little Red Discs | | Image |
| 11 |  | 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 |
| 12 |  | 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 |
| 13 |  | 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 |
| 14 |  | 3-60b - 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 |
| 15 |  | 3-60d - 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 |
| 16 |  | 3-4 - Tilted Disc | Tilted discs are normal variants caused by oblique insertion of the optic nerve to the globe. They can be and frequently are mistaken for papilledema. In this case the superior edge of the disc is tilted and appears elevated. This disc exhibits a nasal inferior tilt. | Image |
| 17 |  | 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 |
| 18 |  | 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 |
| 19 |  | 4-60a - 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. 4-60a mother, 4-60b son. | Image |
| 20 |  | 3-5b - Myelinated Nerve Fibers | Myelinated nerve fibers are frequently confused with papilledema. The feathery edge of the myelinated fibers that conceal the disc and vessel should provide the clue. These myelinated nerve fibers make the disc look blurred. | Image |
| 21 |  | 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 |
| 22 |  | 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 |
| 23 |  | 3-66d - 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 |
| 24 |  | 3-36a - Papilledema Stages | Grading Papilledema: Stage 5 Stage 5 = Dome-shaped appearance with all vessels being obscured. (Sometimes called "champagne cork" swelling--because of its dome shape.) | Image |
| 25 |  | 3-32b - Papilledema Stages | Grading Papilledema: Stage 1 Stage 1 = C shaped blurring of the nasal, superior and inferior borders. Usually the temporal margin is normal. Also notice the chorio-retinal folds (arrows) that eminate toward the macula (m) | Image |
