Phosphenes are thought to be related to another MS-related symptom: L'Hermitte's sign, in which a buzzing electrical sensation takes place briefly in the spine when the head is tilted forward. So-called "movement phosphenes" are known to follow any side-to-side movement of the eye. The imagery will fade eventually, but may still repeat itself after a brief period of rest. Phosphenes in those with MS may be sparked by sudden noises or movement of the gelatinous coating in the eyes, as well. You're just more likely to notice at night.Ībout a third of those with MS who experience optic neuritis also experience phosphenes. Interestingly, they don't happen only at night, but at any time when dysfunctional optic nerve behavior occurs. In optic neuritis, misfiring nerves in the brain by way of the optic nerve can render these strange little light shows.

The most obvious relationship phosphenes have with MS is by way of the common symptom, optic neuritis. Phosphenes are considered a normal phenomenon, but they have also made a brief acquaintance with MS. 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. Strong magnetic fields might also elicit a phosphene response.

Usually, they are caused by sounds, sudden movement, or pressure on the eye, all of which can aggravate or inflame the optic nerve. They occur when the cells in the retina fire in the absence of light, leading to impressions "seen" on the inside of the eyelids that are perceived as stars, bursts, defined shapes like circles, or swirls of light.
