Summary
Transient cortical blindness is a rare complication after angiography. This case shows temporary vision loss resolved spontaneously within 15 hours, suggesting contrast agent disruption of the blood-brain barrier.
Area of Science:
- Neurology
- Ophthalmology
- Radiology
Background:
- Transient cortical blindness (TCB) is an uncommon complication associated with angiography procedures.
- The exact pathophysiology of TCB following angiography remains speculative, but contrast agent-induced blood-brain barrier disruption is a likely mechanism.
Observation:
- A 52-year-old male experienced transient vision loss after undergoing coronary angiography.
- The patient's vision spontaneously returned within approximately 15 hours post-procedure.
Findings:
- Brain magnetic resonance imaging (MRI) revealed no acute pathology.
- The episode of transient vision loss resolved without specific therapeutic intervention.
Implications:
- This case highlights the possibility of TCB following coronary angiography.
- The self-resolving nature of the event suggests a temporary and reversible disruption of neurological function.
