Background
- Bilateral optic disc swelling due to increased ICP
- This may sometimes be a presenting complaint, referred by an eye care provider, though will usually have associated symptoms such as headache, altered mental status, or vision changes.
Etiology
- All causes of elevated intracranial pressure
- Intracranial mass
- Decreased CSF outflow or resorption
- Increased CSF production or cerebral blood flow
- Most commonly caused by Idiopathic intracranial hypertension in individuals under 50.[1]
Clinical Features
- Increased ICP symptoms:
- Headache (esp with recumbency and in the morning)
- Nausea and vomiting
- Visual disturbance
- Visual acuity is usually normal or near-normal in the acute phase
- May have transient visual obscurations (blurriness or white out) that last seconds, then clear completely.[1]
- These may be triggered by position change or Valsalva
Fundoscopy
- Loss of spontaneous venous pulsations
- Disc margin blurring
- Cup is diminished or absent
Differential Diagnosis
- Idiopathic intracranial hypertension (other causes must be excluded)
- Intracranial mass
- Hydrocephalus
- Cerebral venous thrombosis
- Cerebral edema
Evaluation
- Careful neurologic exam including level of consciousness, pupils, and cranial nerves (especially CN VI-Abducens)
- Fundoscopic exam without dilation is often difficult - consider ocular ultrasound to assess optic nerve diameter
- Brain MRI with MR venography to identify secondary causes of elevated ICP
- Non-contrast head CT with CT venography may be a reasonable alternative depending on practice setting and patient urgency. Follow-up MRI may be required.
- Lumbar Puncture (if neuroimaging normal)
- Opening pressure >25 considered abnormal
Management
- Treat underlying condition
