Area of Science:

  • Neurology
  • Radiology
  • Ophthalmology

Background:

  • Transient cortical blindness is an uncommon adverse event associated with contrast media used in angiography.
  • Angiography is a key diagnostic tool in vascular imaging.

Observation:

  • A 64-year-old male developed transient cortical blindness.
  • This occurred subsequent to subclavian arteriography performed to address an occluded axillofemoral graft.

Findings:

  • The patient's visual deficit was temporary, resolving spontaneously.
  • The event underscores a potential neurological complication of iodinated contrast agents.

Implications:

  • Awareness of this rare complication is crucial for clinicians performing and interpreting angiographic procedures.
  • Further research may elucidate mechanisms and preventative strategies for contrast-induced neurotoxicity.
