Cortical blindness after cerebral angiography. Case report

Area of Science:

• Neurology
• Radiology
• Ophthalmology

Background:

• Cerebral angiography is a diagnostic imaging procedure.
• Cortical blindness is a visual impairment resulting from damage to the occipital cortex.

Observation:

• A patient developed cortical blindness following cerebral angiography.
• Computerized tomography (CT) scans showed contrast medium in the occipital visual areas.
• The patient experienced focal seizures post-angiography.

Findings:

• Contrast medium persisted in the brain's visual cortex.
• This persistence may be linked to the observed focal seizures.
• Reduced renal function contributed to the prolonged presence of contrast material.

Implications:

• This case suggests contrast medium can directly cause cortical blindness.
• Understanding contrast agent effects is crucial for patient safety.
• Further research into managing contrast-induced neurological events is warranted.
