Teichopsia

Teichopsia is a neurological symptom that is often associated with migraines. It is characterized by the perception of a zigzag pattern, also known as a "fortification spectrum," which is typically followed by a period of visual impairment known as a scotoma. The term "teichopsia" comes from the Greek words "teichos" (wall) and "opsis" (vision), referring to the fort-like appearance of the zigzag pattern.

Symptoms and Causes

Teichopsia is a type of aura that precedes a migraine. The zigzag pattern typically begins in the center of the visual field and expands outward. This pattern may be colored or black and white, and it usually lasts for less than an hour. Following the aura, a scotoma typically occurs, which can cause partial or complete loss of vision in one or both eyes.

The exact cause of teichopsia is unknown, but it is thought to be related to changes in blood flow in the brain. It may also be related to the release of certain chemicals in the brain during a migraine.

Diagnosis and Treatment

Teichopsia is typically diagnosed based on the patient's description of their symptoms. There are no specific tests for teichopsia, but a doctor may perform a neurological examination to rule out other conditions.

Treatment for teichopsia is focused on managing migraines. This may include medications to prevent migraines or to treat them once they occur. Lifestyle changes, such as avoiding triggers and managing stress, may also be helpful.
