[Acute insufficiency of the chorioretinal circulation]

Area of Science:

• Ophthalmology
• Vascular Neurology

Background:

• Sudden visual acuity loss can significantly impair patients' quality of life.
• Identifying the underlying causes of visual disturbances is crucial for timely intervention.

Observation:

• Six patients presented with a sudden drop in visual acuity and central scotoma.
• Fundus examination revealed ischemic edema and cotton wool bodies in the posterior pole.
• Fluorescein angiography demonstrated delayed choroidal and/or central retinal arterial injection.

Findings:

• All patients exhibited carotid artery circulatory insufficiency.
• The findings suggest a link between carotid artery disease and posterior pole ischemia.
• Choroidal artery obstruction is proposed as a potential mechanism for macular injury.

Implications:

• This study highlights the importance of evaluating carotid artery status in patients with acute visual disturbances.
• Understanding the pathogenesis of macular injury in this context can guide treatment strategies.
• Early detection and management of carotid artery disease may prevent irreversible vision loss.
