Teichopsia
Teichopsia
Teichopsia (pronunciation: tie-kop-see-uh) is a medical term used to describe a specific type of visual aura. It is often associated with migraines and is characterized by the perception of a fortification spectrum, a phenomenon where the individual sees zigzag lines or a pattern resembling the battlements of a castle.
Etymology
The term 'Teichopsia' is derived from the Greek words 'teichos' meaning wall and 'opsis' meaning view or sight. It was first used in the medical literature by Dr. Hubert Airy in the 19th century to describe the fortification spectra he experienced before the onset of a migraine.
Symptoms
Teichopsia is often preceded by a scotoma, an area of decreased vision surrounded by a normal field of vision. The individual may see a pattern of lines, often zigzag, that gradually expands and moves across the field of vision. The lines may be colored or may appear as black and white. This phenomenon usually lasts less than an hour and is followed by a headache.

- Migraine: A type of headache characterized by severe pain, often accompanied by nausea, vomiting, and sensitivity to light and sound.
Treatment
There is no specific treatment for Teichopsia. It is usually a symptom of a migraine and treatment is focused on relieving the symptoms of the migraine. This may include rest, medication, and avoiding triggers.
