Summary

Transient light-induced vision loss can signal severe carotid artery disease. Prompt diagnosis and surgical intervention are crucial to prevent stroke.

Area of Science:

  • Ophthalmology
  • Neurology
  • Vascular Surgery

Background:

  • Ocular ischemic syndrome (OIS) is a severe condition resulting from reduced blood flow to the eye.
  • Carotid artery disease is a primary cause of OIS, often presenting with diverse and sometimes subtle symptoms.

Observation:

  • A case report detailing a 54-year-old male experiencing transient, painless, and asymmetrical visual loss triggered by bright light exposure.
  • This symptom, termed bilateral amaurosis, was investigated through carotid ultrasound and angiography.

Findings:

  • Diagnostic imaging revealed significant bilateral carotid artery disease, including left internal carotid artery occlusion and severe stenosis in the right internal carotid artery and both external carotid arteries.
  • The patient's visual disturbances and abnormal photostress test results resolved completely following a right carotid endarterectomy.

Implications:

  • Light-induced amaurosis is an underrecognized manifestation of OIS linked to substantial carotid occlusive disease.
  • Early identification of this symptom is critical for initiating timely surgical intervention and mitigating the significant risk of stroke.
