A Rare Hydrocephalus Complication: Cortical Blindness.

Area of Science:

• Neuroscience
• Ophthalmology
• Pediatrics

Background:

• Hydrocephalus, an excess of cerebrospinal fluid in the brain, can lead to serious neurological complications.
• Posterior cerebral artery compression from tentorial herniation is a known mechanism for occipital lobe infarction.

Observation:

• Cortical blindness, a rare complication of hydrocephalus, can be challenging to diagnose, particularly in pediatric and vulnerable populations.
• This case highlights a child experiencing ventricular shunt malfunction leading to acquired cortical blindness.

Findings:

• Bilateral occipital lobe infarction, resulting in cortical blindness, is an exceptionally rare consequence of hydrocephalus.
• The underlying cause is the compression of the posterior cerebral artery due to tentorial herniation.

Implications:

• Early recognition and management of hydrocephalus are critical to prevent irreversible vision deficits.
• This case underscores the importance of considering cortical blindness in the differential diagnosis of vision loss in patients with hydrocephalus and shunt issues.
