Alice in Wonderland syndrome is often associated with distortion of sensory perception, which involves visual, somatosensory, and non-visual symptoms. [12] AIWS is characterized by the individual being able to recognize the distortion in the perception of their own body [3] and is episodic. AIWS episodes vary in length from person to person.
Anxiety and headaches accompany the episodes of visual distortion associated with epilepsy. While Valproic acid has been used to treat this type of seizure, [ 20 ] anti-seizure medications appropriate for focal-onset seizures, like oxcarbazapine , have also been used successfully in the treatment of epilepsy-related macropsia.
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
Visual snow as a temporary occurrence under certain conditions is normal and doesn't require intervention. [ citation needed ] Visual snow syndrome is a pathological condition, where visual disturbances persist constantly and may be caused by issues in the visual or nervous system, requiring medical attention.
Hallucinogen persisting perception disorder (HPPD) is a non-psychotic disorder in which a person experiences apparent lasting or persistent visual hallucinations or perceptual distortions after using drugs, [1] including but not limited to psychedelics, dissociatives, entactogens, tetrahydrocannabinol (THC), and SSRIs.
It is light-sensitive and communicates visual messages to the brain. If the retina detaches, it moves and shifts from its normal position. This can cause photopsia, but can also cause permanent vision loss. Medical attention is needed to prevent vision loss. Procedures may include laser treatment, freezing, or surgery.
Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. [6] Certainly, additional symptoms may be present with the amaurosis fugax, and those findings will depend on the cause of the transient monocular vision loss. [citation needed]
