Retinal migraine poses a (rare) danger of permanent vision loss, so you should get checked by a doctor if you suspect you may be affected. Headaches normally accompany or follow the visual symptoms within an hour. Visual symptoms impact just one eye and are more disruptive, commonly including negative visual aura symptoms like partial loss of vision (scotoma) and temporary blindness. Retinal migraine has more disruptive visual symptoms and is the more potentially-dangerous type of ocular migraine. It may be unpleasant, but just hang on - it’ll be over soon! Retinal migraine This type of migraine may occur with or without a headache.

Visual symptoms are short-lived, usually lasting less than an hour, and they’ll always subside. Migraine with aura has the milder symptoms of the two types, more commonly including positive visual aura symptoms like seeing stars, squiggles, etc. calcium channel blockers or beta blockersĪnd here’s how the types of ocular migraines differ… Migraine with aura.Treatments used to prevent migraines include: NSAIDs such as ibuprofen or aspirin may relieve pain, and anti-nausea medications like promethazine may ease discomfort during an ocular migraine - you can buy both over the counter. The visual symptoms can be blamed on rogue electrical activity in the occipital lobe that spreads very slowly - just a few millimeters per minute - and interferes with visual processing.

These may be accompanied or followed by other migraine symptoms such as: Symptoms of ocular migraines include positive, negative, and altered visual auras, and may also include sensory or dysphasic auras - all of which are described under the Symptoms heading found above. Those affected by ocular migraines commonly experience different symptoms with each episode, and fewer than 20 percent of people who have them experience visual aura symptoms each time they have a migraine. Let’s first discuss what they have in common before pointing out some key differences. There are two kinds of ocular migraine to consider which have similar symptoms but present different levels of danger: migraine with aura, and retinal migraine. The most common of all causes of kaleidoscope vision, this type of migraine is characterized by any number of other possible visual disruptions. So, what on earth can cause kaleidoscope vision? In addition to migraine, there are a few other conditions that could be to blame. These cause the arm and leg on one side of the body, and potentially the face, to feel weak. These cause difficulty with language or speech. These begin with a tingling sensation or numbness in one hand that moves up along the arm, perhaps reaching the face within 20 minutes. While less common, it may also be accompanied or followed by another type of aura, if your other senses feel like getting in on the fun.

distorted distance of objects (they appear closer or further than actual)Ī visual aura may affect one or both eyes and may be accompanied or followed by a headache.

distorted size of objects (they appear larger or smaller than actual).

color distortion or lack of color vision.

These distort the way you see objects without adding or removing anything from your vision.

loss of peripheral vision (aka tunnel vision).

blind spots or partial loss of vision (aka scotoma).

These are characterized by partial or total loss of vision.

shimmering zigzag lines which may move or grow.

seeing stars, dots, squiggly lines, or flashes resembling the afterimage of a flash of light.

Types of visual auras and their symptoms include: There are three types of visual auras, and each can have different effects. Read on for more info about the possible causes of kaleidoscope vision and their treatments.ĭon’t get the wrong idea - having kaleidoscope vision doesn’t necessarily resemble looking through an actual kaleidoscope, nor is it the only type of visual distortion associated with a visual migraine aura. Kaleidoscopes are neat toys, but fractured vision without the help of one is no bueno. They can affect all or just part of your field of vision, and they generally last no more than an hour most often they last between 10 to 30 minutes. Visual auras may be accompanied by a headache and may not affect both eyes equally. The aura itself is not a condition, but a symptom of another condition - usually a migraine, but there are other, more serious possibilities to rule out as well. Visual auras can also disturb other senses such as touch, smell, or hearing. Kaleidoscope vision is generally the result of a visual disturbance called a migraine aura, which is caused by an electrical flare in the occipital lobe of the brain - the area responsible for processing images. This can be alarming, especially if you don’t recall taking the “ brown acid.” When your vision becomes scrambled, fractured, or vividly colorful, you’re experiencing kaleidoscope vision.
