Etiology of papilledema

  • Papilledema refers to passive disc edema caused by increased intracranial pressure
  • It is usually bilateral, although unilateral papilledema can exist in certain conditions

Conditions causing increased intracranial tension and papilloedema:

  • Congenital conditions
    • craniosynostosis
    • aqueductal stenosis
  • Intracranial space occupying lesions (ICSOL’s)
    • especially lesions in the midbrain, cerebellum, occipital lobe and parietal lobe (as they tend to cause greater block to drainage of CSF)
    • Fast growing lesions result in rapid development of papilledema
  • Intracranial haemorrhage
  • Intracranial infections like meningitis, encephalitis
  • Cerebral oedema following blunt injury to head
  • Block in arachnoid granulations
  • Systemic conditions
    • Malignant hypertension
    • Pregnancy induced hypertension
  • Idiopathic intracranial hypertension
