Metamorphopsia

Metamorphopsia (Greek μέταμφωψία - “fake vision”; translation from modern Russian) is a psychological illusion that manifests itself in a distorted perception of reality. Neurophysiologists associate such transformations of visual information with disruption of the central nervous system and visual pathways.

Metamorphopsia can be considered as a special case of perceptual illusions that arise due to defects in the visual apparatus, misunderstanding of visual stimuli, or so-called optical anomalies of the environment. If a person misinterprets light waves, then visual sensations may change. This phenomenon occurs as a result of a violation of color discrimination when

Metamorphopsia is a visual impairment characterized by distortions in the shape and size of visible objects. These distortions can occur both at the periphery of the visual field and in the central region. In this article we will look at what metamorphopsia is, what types exist and how they manifest themselves.

Metamorphopsia is a term used to describe the loss of the ability to perceive colors simultaneously with a distortion in the perception of contrast between colors. Usually this is accompanied by traces of previous visual images, and when trying to focus the gaze on them, the patient again experiences the same cloudings and darkening. The cause of the disorder may be a change in the sensitivity of the retina, which can only be determined by ophthalmoscopy. It is important to pay attention to accompanying symptoms such as headache, dizziness and nausea. If these signs persist for a long time, you should consult a doctor for diagnosis and treatment.

The disorder can be a symptom of various eye diseases, such as glaucoma or cataracts, as well as neurological disorders. An examination by an ophthalmologist and comprehensive studies will help identify the cause of the opacities and prescribe the correct treatment. To prevent metamorphosis, it is recommended to take vitamin complexes, rest on time and use sunglasses.
