You shouldn’t drive or do anything else while you’re having a migraine aura. A migraine aura lasts only a few minutes, but it can cause severe pain. When you get an aura, it means that there is an abnormality in your brain. Migraine AurasĪuras are caused by abnormal electrical activity in the part of your brain called the occipital lobe. They may also be accompanied by other symptoms such as nausea, vomiting, numbness, tingling, pain, and sensitivity to sound. Auras typically begin with flashing lights or blind spots. When this occurs, doctors call it a “visual aura.”Īuras are warning signs that happen before a migraine headache begins. Some people who suffer from migraine headaches also experience kaleidoscope vision. There are many instances where kaleidoscope vision occurs when you suffer a migraine. Still another theory states that kaleidoscope vision could occur due to a temporary loss of consciousness. One theory suggests that kaleidoscope vision happens because the brain is trying to make sense of the rapidly changing images.Īnother theory says that kaleidoscope vision is caused by a malfunctioning eye muscle. However, there are several theories about what causes kaleidoscope vision. The cause of kaleidoscope vision is not fully understood. If you see prisms or other patterns while looking at something, such as a wall, floor, ceiling, tree, etc., this may be kaleidoscope vision. How can you tell if your vision is experiencing kaleidoscope vision? It’s also known as “flashing vision” or “flashback vision.” The term kaleidoscope vision was first used in 1878 by Sir William Crookes, who described it as “a sudden change from one thing to another without transition.” If you would like to learn more about ocular migraines, contact your eye specialist, or call us at Shanbom Eye Specialist.Kaleidoscope vision is a type of visual perception that occurs when the eyes are focused on an object or scene, and then suddenly shift focus to another. A helpful first step is a visit to the ophthalmologist, who can rule out any disorders of the delicate and irreplaceable retina at the back of the eye as well as evaluate the optic nerve for any pathology. The symptoms of an ocular migraine can mimic those of other serious conditions such as retinal detachment, retinal artery thrombosis (a clot in one of the vessels that supplies blood to the retina), transient ischemic attacks (temporary loss of blood flow to areas of the brain), or stroke. These might include strong lights, certain foods, stress, overexertion, and sleep deprivation. The best way to avoid ocular migraines is to avoid known triggers. Simply sitting down and waiting for it to pass should help prevent any physical harm that could come as a result of vision distortion. For example, if driving, the patient should pull over to the side of the road and wait for it to pass. When an ophthalmic migraine interferes with the vision, patients should take some safety precautions. Typically, the vision in only one eye is affected, and these visual disturbances are consistent from one episode to the next. These effects can occur individually or in combination. Scintillations, flickering or flashing lights Scotoma, a blind spot that gradually increases in size Ocular migraine symptoms usually include: This is referred to as an ocular or ophthalmic migraine. However, some people experience these visual disturbances without the pain of a migraine headache. Auras that precede or occur at the same time as migraine headaches can include visual symptoms that include flashes of light, blind or shimmering spots, kaleidoscope or zigzag patterns in your field of vision. Visual disturbances with migraine headaches are quite common.
