What is a Hollenhorst plaque?

A Hollenhorst plaque is a clinical sign. It is commonly a contributing factor in the diagnosis of retinal artery occlusion (RAO). In order for a Hollenhorst plaque to cause an RAO, the plaque must completely obstruct the vessel.  RAOs can occur in the central retinal artery (CRAO) or one of its branches (BRAO). Hollenhorst plaques are only one possible cause of a CRAO/BRAO and should not be thought of as synonymous. As discussed in the differential diagnoses, other types of emboli exist with the ability to occlude. There are also non-embolic causes of retinal artery occlusion including nocturnal arterial hypotension and transient vasospasm. Hollenhorst plaques, like other types of retinal emboli, may not stay in one place. The plaque may dislodge and move to a smaller diameter vessel before it gets lodged again, or the plaque may dissolve completely. The presence of a Hollenhorst plaque is a confirming diagnosis; however, the absence of a plaque does not rule out the possibility of embolic occlusion.

Where does Hollenhorst plaque originate?

Hollenhorst plaques tend to originate from carotid arteries or the aorta. This finding is consistent with carotid disease originating from atherosclerotic lesions.  The initial assumption, among eye care providers, upon discovering a Hollenhorst plaque is that it originated from the stenosed, ipsilateral internal carotid artery. The direct anatomical route between the internal carotid artery (ICA) and central retinal artery (CRA) supports this assumption. The ophthalmic artery is the first branch of the ICA, which then leads into the CRA. [3][4]

How prevalent are retinal emboli?

The prevalence increases with age. Retinal emboli are significantly more prevalent in men than in women. Hollenhorst plaques make up the majority of the retinal emboli at 80%. An estimated 10% of carotid emboli reach the retinal arteries. [5]

What is the ocular test for occlusion?

Ocular testing may involve fluorescein angiography (FA) as a supplemental test. Expected results for an occlusion include: delay in the retinal arterial filling, delayed arteriovenous transit time, and variable amounts of residual retinal circulation. It is very rare to see a complete lack of retinal filling even though the vessel is completely occluded. The choroidal filling should be normal since the occlusion has occurred anterior to the ophthalmic artery. There is also a restoration of retinal circulation within days/weeks after an RAO via anastomoses with the central retinal artery; therefore, an FA is of little benefit if delayed. [4][9]

Can a carotid artery cause monocular blindness?

Ulcerated plaques just distal to the bifurcation of the common carotid artery into its external and internal branches may be a source of retinal emboli that can be asymptomatic or produce transient monocular blindness. [6][7]

Is platelet fibrin emboli a refractile disease?

Platelet-fibrin emboli: White/gray, dull (non-refractile), elongated. This can be a finding for both cardiac and carotid disease; however, cholesterol emboli are more common in carotid disease.

Which type of cell can fall off the main lesion and lodge in the retinal arterioles?

Tumor cells: These proliferative neoplastic cells which can fall off the main the main lesion and lodge in the retinal arterioles.
