Hollenhorst

Hollenhorst plaque is a medical condition characterized by the presence of cholesterol crystals in the retinal arteries. These plaques are typically associated with a higher risk of stroke and other cardiovascular diseases. The condition is named after Robert Hollenhorst, a renowned ophthalmologist who first described the condition.

Symptoms[edit | edit source]

Hollenhorst plaques are usually asymptomatic, meaning they do not cause any noticeable symptoms. However, they can occasionally cause transient visual loss, known as amaurosis fugax. This occurs when the plaques temporarily block blood flow to the retina.

Causes[edit | edit source]

The primary cause of Hollenhorst plaques is atherosclerosis, a condition characterized by the buildup of fats, cholesterol, and other substances in and on the artery walls. Other risk factors include high blood pressure, diabetes, and smoking.

Diagnosis[edit | edit source]

Hollenhorst plaques are typically diagnosed during a routine eye examination. The plaques appear as bright, refractile lesions in the retinal arteries. Additional tests, such as carotid ultrasound or magnetic resonance angiography (MRA), may be performed to assess the extent of atherosclerosis.

Treatment[edit | edit source]

Treatment for Hollenhorst plaques primarily involves managing the underlying atherosclerosis. This may include lifestyle changes, such as quitting smoking and adopting a healthier diet, as well as medication to control blood pressure and cholesterol levels. In some cases, surgical intervention may be necessary.
