Systemic disease and the eye Papilloedema True papilloedema is a swollen optic nerve head due to raised intracranial pressure – this results from impaired axoplasmic flow. Disc swelling can also occur in the absence of raised intracranial pressure, this can be due to disruption of axoplasmic flow, ischaemia or compressive states and oedema. Causes include: Raised intracranial pressure Cerebral mass lesion (tumour, abscess) Hydrocephalus, haemorrhage, haematoma Idiopathic intracranial hypertension Obstruction of ocular venous drainage Central retinal vein occlusion Cavernous sinus thrombosis Systemic disorders affecting retinal vessels Hypertension Vasculitis Hypercapnia Optic nerve damage Demyelination Leber's hereditary optic neuropathy Ischaemia Toxins – methanol, carbon monoxide Infiltration of optic disc Sarcoidosis Glioma Lymphoma
