What might be a consequence of carotid artery atherosclerosis for those with retinal artery occlusion?

Carotid artery atherosclerosis can have significant implications for various vascular systems in the body, particularly concerning the brain and the eyes. The correct answer, which highlights the increased risk of stroke, reflects the underlying pathology of atherosclerosis affecting the carotid arteries.

When atherosclerosis develops, plaque builds up in the carotid arteries, narrowing them and potentially leading to turbulent blood flow. This condition can result in emboli—small clots or debris—that can dislodge and travel to other parts of the body, including the retinal arteries. A retinal artery occlusion can occur as a result, leading to vision loss. The same mechanisms that impair blood flow to the retina can also increase the risk of strokes, as the compromised blood flow can result in ischemic events in the brain if the carotid arteries become significantly blocked or an embolus travels upward.

Consequently, individuals with carotid artery atherosclerosis and retinal artery occlusion share a heightened risk for cerebrovascular accidents due to the interconnected nature of vascular health, making stroke a direct and critical consequence of the underlying atherosclerotic disease.

The other options involve complications that are not directly linked to the primary pathophysiological processes at play with carotid artery atherosclerosis
