Papilledema
- Signs
- Early and mild Papilledema
- Subtle gray peripapillary halo
- Normal radial Optic Nerve head disrupted
- Nerve fibers accentuated by grayish opacity
- Concentric folds of the retinochoroid
- Subtle gray peripapillary halo
- Moderate Papilledema
- Borders of optic disc become obscure
- Disc margins are progressively elevated
- Nerve head diameter increases
- Major blood vessels leaving the disc are obscured
- Severe Papilledema
- Optic Nerve head protrudes
- Peripapillary halo demarcated
- Optic cup is obliterated
- Early and mild Papilledema
- Associated findings
- Loss of spontaneous retinal vein pulsations
- Pulsations disappear at CSF Pressure > 250 mm water
- Unreliable sign
- Many normal patients lack venous pulsations
- Hyperemia
- Retinal vessel tortuosity
- Retinal hemorrhages
- Retinal exudates
- Nerve fiber infarctions (cotton wool spots)
- Optic Nerve pallor
- Loss of spontaneous retinal vein pulsations
- Interpretation
- Suggests increased Intracranial Pressure
- Causes: Pseudopapilledema
- Optic disc drusen
- Tilted optic disc
- Diagnostics
- Stereoscopic indirect fundoscopy
- Optic Nerve ultrasound
- Drusen are highly reflective
- Papilledema shows a distended Optic Nerve sheath
Papilledema (C0030353) | |
|---|---|
| Definition (MSH) | Swelling of the OPTIC DISK, usually in association with increased intracranial pressure, characterized by hyperemia, blurring of the disk margins, microhemorrhages, blind spot enlargement, and engorgement of retinal veins. Chronic papilledema may cause OPTIC ATROPHY and visual loss. (Miller et al., Clinical Neuro-Ophthalmology, 4th ed, p175) |
| Definition (CSP) | swelling of the optic disk, usually in association with increased intracranial pressure, characterized by hyperemia, blurring of the disk margins, microhemorrhages, blind spot enlargement, and engorgement of retinal veins. |
| Definition (NCI) | (pap-il-eh-DEE-ma) Swelling around the optic disk, the area where the optic nerve (the nerve that carries messages from the eye to the brain) enters the eyeball. Papilledema occurs when increased brain pressure caused by tumors or other problems results in swelling of the optic nerve. |
| Definition (NCI) | Swelling around the optic nerve, usually due to pressure on the nerve by a tumor. |
