Whether or not treatment is available to those with palinopsia depends on the cause of the disorder. For example, if it is related to seizures, then seizure medication may mitigate the symptoms. However, for most sufferers, palinopsia is considered a lifelong condition.

Pathophysiology. Illusory palinopsia is a dysfunction of visual perception, resulting from diffuse, persistent alterations in neuronal excitability that affect physiological mechanisms of light or motion perception. Illusory palinopsia is caused by migraines, HPPD, prescription drugs, head trauma, or may be idiopathic.

Oscillopsia is a vision problem in which objects appear to jump, jiggle, or vibrate when they’re actually still. The condition stems from a problem with the alignment of your eyes, or with the systems in your brain and inner ears that control your body alignment and balance.

Visual snow is a neurological disorder characterized by a continuous visual disturbance that occupies the entire visual field and is described as tiny flickering dots that resemble the noise of a detuned analogue television.

The cause of visual snow is unclear. Those affected typically also have migraines. The underlying mechanism is believed to involve excessive excitability of neurons in the right lingual gyrus and left cerebellar anterior lobe of the brain.

Summary. Visual snow syndrome affects the way the visual information is processed by the brain and eyes. People with visual snow syndrome see many flickering tiny dots, like snow or static, that fill the entire visual field.

The most common cause of kaleidoscopic vision is a visual migraine. This may also be called an ocular or ophthalmic migraine. The technical term for it is scintillating scotoma. It most often occurs in both eyes.

Most people with visual snow syndrome see these tiny dots all the time in both eyes. It may get worse after looking at a screen for a long period of time or during times of high stress.

The perception of visual snow does not appear to worsen significantly following its initial appearance. It is generally not progressive. On the other hand, visual snow rarely disappears once it appears.

Visual snow syndrome is a very rare disease which can be detrimental to patients. It is often described as a visual disturbance present in the entire visual field with flickering white and black dots, similar to the static seen on an analogue television [2].

Most people see splashes of colors and flashes of light on a not-quite-jet-black background when their eyes are closed. It’s a phenomenon called phosphene, and it boils down to this: Our visual system — eyes and brains — don’t shut off when denied light.

Something that looks like heat waves shimmering in your peripheral vision? If you have, you may have been experiencing what is known as an ocular migraine. Ocular migraines occur when blood vessels spasm in the visual center of the brain (the occipital lobe) or the retina.

Ablutophobia, like all phobias, is an anxiety disorder. It’s clinically known as a specific phobia, which is an excessive or unreasonable fear of an object or situation. 1 It can manifest in many ways, from a fear of showering to a complete phobia of all washing.
