Kaleidoscope vision is a visual illusion created by the brain through which you possibly can see brilliant or fractured colours, similar to people who will be seen through this object. It occurs as one among the auras of retinal migraine, but might also be related to other more serious pathologies, similar to transient ischemic attacks and retinal detachment.
The term aura refers to sensory disturbances that will occur prior to the onset of a migraine headache. Kaleidoscope vision isn’t the one associated visual disturbance, as blind spots or brilliant lights might also be seen.
Auras or sensory disturbances may affect as much as 20% of individuals with migraine. They precede the pain and last roughly half-houralthough they’ll last anywhere from 5 minutes to 1 hour.
The headache normally occurs 10 to quarter-hour after the aura.
What’s kaleidoscope vision?
Kaleidoscope vision is an illusion produced by alterations within the visual cortex of the brain. Colours are brighter or fractured and sometimes images move.
It will probably affect one or each eyes, in addition to only a part of the visual field or your complete visual field.
It’s the results of a sudden increase in neuronal activity and occurs with or without pain. The medical term is scintillating scotoma.
Visual or ocular migraine is the most important reason behind kaleidoscope vision. Nonetheless, it could also occur in retinal migraine, strokes, or as a consequence of hallucinogen use.
Ocular migraine
The so-called visual or ocular migraine is as a consequence of structural abnormalities within the neurons of the visual cortex. It might take as much as an hour after kaleidoscope vision to experience the headache. As in other cases, there could also be no headache, which is named acetalgic migraine.
Sensory disturbances normally last between 10 and half-hour, but may extend for 1 hour. Along with being brought on by structural abnormalities of the visual cortex, they could be as a consequence of binocular visual dysfunction (improper alignment of the eyes).
Retinal migraine
Although it could be confused, a retinal migraine as a reason behind kaleidoscope vision has similar symptoms, although the origin is different. It’s a response to reduced blood flow to the retina, so the symptoms are unilateral.
Along with kaleidoscope vision, it causes flickering lights, blind spots or temporary blindness. The associated headache is throbbing and occurs in the course of the top on the side of the affected eye.
In visual or ocular migraine, the distorted image is in each eyes. In retinal migraine, it’s in just one eye.
To ensure if each eyes are affected, it’s really useful to cover one eye after which the opposite. If each eyes are affected, the image is distorted in each eye individually.
Stroke (CVA)
That is brought on by blockage of blood flow to the brain. It might be related to damage to the blood vessels, blood clots blocking the passage, or a narrowing as a consequence of the presence of plaques with fatty deposits.
It’s often called a transient stroke is a brief blockage through which symptoms last from just a few minutes to a maximum of 24 hours. Following a stroke or transient ischemic attack, there’s a high probability of getting one other stroke in the long run.
Any symptoms of a stroke ought to be reported to doctors immediately. Symptoms vary widely and include the next:
- Confusion
- Difficulty speaking
- Lack of consciousness
- Lack of balance and dizziness
- Tingling or numbness on one side of the body

Hallucinogen use
Lysergic acid diethylamide (often called LSD) and mescaline produce visual distortions with the presence of very brilliant, but unstable, coloured images that may resemble what’s visualized when searching through a kaleidoscope. For this reason the consumption of hallucinogens ought to be ruled out as a cause.
Kaleidoscope vision is an altered visual aura
The differing types of visual aura change the best way through which the person visualizes his or her surroundings.
There are three variants:
- Positive visual aura: Where a picture is visualized that isn’t actually there. It will probably be zigzag lines, squiggles, flashes, or dots.
- Negative visual aura: There’s a lack of vision that will be partial or total, i.e., starting from blind spots or lack of peripheral vision (tunnel vision) to a temporary period of total lack of vision.
- Altered visual aura: On this variant, what’s visualized is distorted, without adding or subtracting anything. Objects are seen as a straight, wavy, or blurred line. Perception of object size, distance, and color might also be modified.
There’s no specific treatment for kaleidoscope vision
Currently, there’s no cure for migraines. Kaleidoscope vision, like all other associated symptom, normally disappears inside 1 hour. Nonetheless, medications will be given to stop or relieve the headache. Sitting or lying down in a dark, quiet room, massaging the scalp, and using a warm compress on the brow are also really useful.
Over-the-counter pain relievers, similar to ibuprofen, are helpful. In some cases, beta-receptor blockers or calcium channel blockers are indicated.

It’s a scary symptom
Kaleidoscope vision will be frightening, especially the primary time it occurs. Nonetheless, it normally subsides inside just a few minutes, so calm down and wait on your vision to return to normal before walking, driving, or operating machinery. The causes of ocular migraine vary from individual to individual. On many occasions, they’ll’t be determined.
Some foods, similar to caffeine or chocolate, in addition to stressful conditions, will be triggers.
An ophthalmologist should all the time be consulted if kaleidoscope vision is present.
