Things worth knowing about "Papilloedema"

Papilloedema is a swelling of the optic nerve head caused by raised intracranial pressure. It is a serious medical emergency requiring prompt evaluation.

What Is Papilloedema?

Papilloedema refers to swelling of the optic disc – the point where the optic nerve enters the eye and becomes visible on the retina. This swelling is typically caused by raised intracranial pressure (ICP) and usually affects both eyes simultaneously. Papilloedema is a serious neurological warning sign and always requires urgent medical investigation to identify and treat the underlying cause.

Causes

Papilloedema almost always results from elevated pressure within the skull. Common causes include:

Brain tumours (benign or malignant) obstructing cerebrospinal fluid (CSF) flow
Hydrocephalus (accumulation of CSF within the brain)
Meningitis or encephalitis (infection or inflammation of brain coverings)
Intracranial haemorrhage (e.g., subdural or subarachnoid bleeding)
Idiopathic intracranial hypertension (pseudotumour cerebri) – most common in overweight women of childbearing age
Cerebral venous sinus thrombosis (clots in the brain's venous sinuses)
Hypertensive crisis with severely elevated blood pressure

Symptoms

In early stages, papilloedema may cause few or no visual symptoms. As pressure increases, the following may occur:

Brief, transient visual obscurations lasting seconds (greying or blackening of vision)
Headaches, often worse in the morning or when bending forward
Nausea and vomiting
Double vision (diplopia), often due to sixth cranial nerve palsy
Enlargement of the blind spot on visual field testing
In advanced stages: permanent visual field loss or even blindness

Diagnosis

Diagnosis is primarily made through an ophthalmological examination:

Fundoscopy (ophthalmoscopy): Direct visualisation of the optic disc; papilloedema appears as blurred disc margins, disc elevation, and peripapillary haemorrhages
Optical coherence tomography (OCT): Precise measurement of the retinal nerve fibre layer thickness
Visual field testing (perimetry): Detection of visual field defects
Neuroimaging: MRI or CT scan of the brain to identify causes such as tumours, bleeds, or hydrocephalus
Lumbar puncture: Measurement of CSF opening pressure and analysis of spinal fluid
Blood pressure measurement: Exclusion of hypertensive crisis

Treatment

Treatment is directed at the underlying cause of raised intracranial pressure:

Brain tumour: Surgery, radiotherapy, or chemotherapy depending on tumour type and location
Hydrocephalus: CSF shunting procedures
Meningitis or encephalitis: Antibiotics or antiviral therapy
Idiopathic intracranial hypertension: Weight loss, acetazolamide (to reduce CSF production), therapeutic lumbar puncture, or optic nerve sheath fenestration in severe cases
Hypertensive crisis: Emergency blood pressure reduction
Cerebral venous sinus thrombosis: Anticoagulation therapy

Early treatment is essential to prevent permanent damage to the optic nerve and irreversible vision loss.

Distinction From Pseudopapilloedema

Not every elevated or unusual-looking optic disc indicates true papilloedema. Pseudopapilloedema – caused by optic disc drusen or high hyperopia – can mimic the appearance of papilloedema without raised intracranial pressure. Differentiation is achieved through OCT, fluorescein angiography, and neuroimaging.
