Ocular ischemic syndrome: long-term ocular complications.

Area of Science:

• Ophthalmology
• Vascular Surgery
• Neurology

Background:

• Acute retinal arterial occlusive events are typically linked to carotid artery embolic disease and diagnosed noninvasively.
• Chronic retinal and choroidal impairments from ophthalmic artery insufficiency are often associated with severe carotid occlusive disease.
• These chronic conditions present diverse clinical features, making diagnosis difficult.

Purpose of the Study:

• To present the diagnostic and management experience of a senior author in complex cases of ophthalmic artery insufficiency.
• To highlight the challenges in recognizing chronic circulatory impairments due to carotid occlusive disease.

Main Methods:

• Review of clinical experience in diagnosing and managing patients with ophthalmic artery insufficiency.
• Noninvasive imaging techniques for evaluating carotid artery disease and its impact on ocular circulation.

Main Results:

• Acute events are generally recognized, with embolic sources often identified.
• Chronic impairments present diagnostic challenges due to varied clinical presentations.
• High-grade, hemodynamically significant carotid occlusive disease is a common cause.

Conclusions:

• Ophthalmic artery insufficiency due to carotid disease requires careful diagnosis due to its complex nature.
• Effective management relies on recognizing the diverse clinical manifestations and underlying carotid pathology.
• Further experience sharing is valuable for improving patient outcomes.
