- May have visual obscurations that clear completely lasting seconds
Fundoscopy
- Loss of spontaneous venous pulsations
- Disc margin blurring

Differential Diagnosis
- Malignant hypertension
- Idiopathic intracranial hypertension (pseudotumor cerebri)
- Intracranial mass
- Hydrocephalus
- Cerebral edema
- Salicylate toxicity
Evaluation
- MRI
- CT (if MRI unavailable)
- LP (if neuroimaging normal)
- Opening pressure >25 considered abnormal
Management
- Treat underlying condition
