Tekhopsia (Tekhopsia)

Teichopsia is a combination of visual perception of flickering multi-colored lights and areas of the visual field free from them (transient scotoma). This phenomenon is a type of visual hallucination.

Teichopsia is often observed at the very beginning of the development of a migraine attack. Patients describe the appearance of multi-colored flashes, sparks, spots or lines in their field of vision. These visual hallucinations may move, flicker, or pulsate. Sometimes they cover part of the visual field, creating a feeling of “falling out” of areas of the image - the so-called transient scotoma.

The appearance of teichopsia indicates the onset of a migraine aura. This migraine phase can last about 20 minutes. It is followed by the development of other symptoms - headache, nausea, photophobia.

Teichopsia is one of the most common manifestations of migraine with aura. The reasons for this phenomenon are not entirely clear; it is presumably associated with a wave of depolarization spreading across the visual cortex at the beginning of the attack. Diagnosis of teichopsia is based on a characteristic description of symptoms and their relationship with the development of migraine. Treatment is aimed at stopping the headache attack itself.

Teichopsia

Teichopsia is a condition that occurs when a person's visual system is unable to adequately process peripheral vision information. As a result, the perception of objects in the field of view is distorted. The teichopsia effect is characterized as the appearance of flicker-free segments of visible space that may appear more distant or distorted in color. It seems possible to describe teichopsia as a phenomenon when the level of functioning of the visual system is not high enough, which leads to increased susceptibility to visual stimuli within the area of ​​​​operation of the eye

**What is teichopsia?**

Teichopsia is a condition characterized by the appearance of flickering multi-colored dots in the visual field, but without visual obstructions.

It often occurs in people suffering from migraine during the initial period of an attack, although it can also occur with various visual impairments and mental illnesses. Usually flicker
