A phosphene is the phenomenon of seeing light without light actually entering the eye. The word phosphene comes from the Greek words phos light and phainein to show.

Phosphenes can be directly induced by mechanical, electrical, or magnetic stimulation of the retina or visual cortex , or by random firing of cells in the visual system.

Phosphenes have also been reported by meditators [4] called nimitta , people who endure long periods without visual stimulation the prisoner's cinema , or those who ingest psychedelic drugs.

The most common phosphenes are pressure phosphenes, caused by rubbing or applying pressure on or near the closed eyes. They have been known since antiquity, and described by the Greeks.

Experiences include a darkening of the visual field that moves against the rubbing, a diffuse colored patch that also moves against the rubbing, well defined shapes such as bright circles that exist near or opposite to where pressure is being applied, [7] a scintillating and ever-changing and deforming light grid with occasional dark spots like a crumpling fly-spotted flyscreen , and a sparse field of intense blue points of light.

Pressure phosphenes can persist briefly after the rubbing stops and the eyes are opened, allowing the phosphenes to be seen on the visual scene.

Hermann von Helmholtz and others have published drawings of their pressure phosphenes. One example of a pressure phosphene is demonstrated by gently pressing the side of one's eye and observing a colored ring of light on the opposite side, as detailed by Isaac Newton.

Another common phosphene is "seeing stars" from a sneeze , laughter, a heavy and deep cough, blowing of the nose , a blow on the head or low blood pressure such as on standing up too quickly or prior to fainting.

It is possible these involve some mechanical stimulation of the retina, but they may also involve mechanical and metabolic such as from low oxygenation or lack of glucose stimulation of neurons of the visual cortex or of other parts of the visual system.

Less commonly, phosphenes can also be caused by some diseases of the retina and nerves, such as multiple sclerosis.

The British National Formulary lists phosphenes as an occasional side effect of at least one anti-anginal medication. The name "phosphene" was coined by J.

Phosphenes have been created by electrical stimulation of the brain, reported by neurologist Otfrid Foerster as early as Brindley and Lewin inserted a matrix of stimulating electrodes directly into the visual cortex of a year-old blind female, using small pulses of electricity to create phosphenes.

These phosphenes were points, spots, and bars of colorless or colored light.

Auch Medikamente rufen Phosphene hervor.

Phosphene Strong magnetic fields might also elicit a phosphene response. If you’ve ever closed your eyes and rubbed really hard, you may experience an eye-shaped phosphene projected onto your eyelid afterward that lasts for a second or more before disappearing. Phosphenes and multiple sclerosis. Phosphine (IUPAC name: phosphane) is a colourless, flammable, very toxic gas compound with the chemical formula PH 3, classed as a pnictogen phosphine is odourless, but technical grade samples have a highly unpleasant odour like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4). phosphene: [ fos´fēn ] an objective visual sensation that occurs with the eyes closed, and in the absence of retinal stimulation by visible light. Phosphene definition is - an impression of light that occurs without light entering the eye and is usually caused by stimulation of the retina (as by pressure on the eyeball when the lid is closed) or by excitation of neurons in the visual system (as by transcranial magnetic stimulation). A phosphene is the phenomenon of seeing light without light actually entering the eye. The word phosphene comes from the Greek words phos (light) and phainein (to show).
