Summary
Transient cortical blindness is a rare complication of coronary angiography, potentially caused by contrast agents disrupting the blood brain barrier. This case highlights temporary vision loss and occipital lobe involvement, resolving within 48 hours.
Area of Science:
- Neurology
- Radiology
- Ophthalmology
Background:
- Cortical blindness is a rare complication following cerebral angiography.
- Contrast agents are implicated in the development of post-angiography blindness.
- The exact mechanism of contrast-induced blood-brain barrier disruption in occipital areas remains unclear.
