Angioid streaks

Angioid Streaks

Angioid streaks (pronounced: an-gee-oid streaks) are a clinical finding in the retina of the eye. They are characterized by irregular, jagged lines that radiate outwards from the optic disc.

Etymology

The term "angioid streaks" is derived from the Greek words "angeion" meaning vessel and "eidos" meaning form or shape. This is due to the streaks' resemblance to blood vessels in their pattern and distribution.

Definition

Angioid streaks are breaks in Bruch's membrane, a thin layer of tissue located in the retina. These breaks appear as dark, irregular lines that radiate outwards from the optic disc. They are often associated with certain systemic diseases, such as Pseudoxanthoma elasticum, Ehlers-Danlos syndrome, and Paget's disease of bone.

Clinical Significance

Angioid streaks are typically asymptomatic and are often discovered during routine eye examinations. However, they can lead to complications such as choroidal neovascularization, which can cause vision loss if left untreated.

Diagnosis

Diagnosis of angioid streaks is typically made through a comprehensive eye examination, including a dilated fundus examination and optical coherence tomography. In some cases, fluorescein angiography may be used to confirm the diagnosis.

Treatment

Treatment for angioid streaks is typically aimed at managing any underlying conditions and preventing complications. This may include regular eye examinations, use of anti-VEGF medications, and in some cases, laser photocoagulation or photodynamic therapy.
