Hollenhorst plaque
Hollenhorst plaque
Hollenhorst plaque (pronounced: hohl-en-horst pla-k) is a medical term referring to a bright, cholesterol-rich embolus lodged in the retinal arterioles. It is named after Robert Hollenhorst, a renowned ophthalmologist who first described the condition.
Etymology
The term "Hollenhorst plaque" is derived from the name of the ophthalmologist Robert Hollenhorst, who first identified and described the condition in the mid-20th century. The word "plaque" comes from the Greek word "plakous," which means "flat and broad."
Definition
A Hollenhorst plaque is a bright, cholesterol-rich embolus that is typically lodged in the retinal arterioles. It is often associated with carotid artery disease and can be a sign of significant systemic vascular disease. The plaque can cause a blockage in the blood vessels of the eye, leading to vision problems or even blindness.
Symptoms
Symptoms of a Hollenhorst plaque may include sudden, painless vision loss or a field defect. However, many patients with Hollenhorst plaques are asymptomatic and the plaques are often discovered during routine eye examinations.
Diagnosis
Diagnosis of a Hollenhorst plaque is typically made through a comprehensive eye examination, including a dilated fundus examination. Additional tests such as fluorescein angiography or optical coherence tomography may also be used.
Treatment
Treatment for Hollenhorst plaque primarily involves managing the underlying vascular disease. This may include medications to control cholesterol and blood pressure, lifestyle modifications, or in some cases, surgical intervention.
