movement phosphene
   A term introduced in or shortly before 1976 by the American neurologists Floyd A. Davis et al. to denote a type of * phosphene (i.e. a transient flash or spark of light) that may be evoked by eye movement. Etiologically, movement phosphenes are associated primarily with optic neuritis and multiple sclerosis. They should not be confused with *flick phosphenes, which occur physiologically. As noted by Davis et al., the movement phosphene is conceptualized as a clinical sign analogous to the Lhermitte sign in cervical cord lesions. The term movement phosphene is used in opposition to the terms * convergence phosphene, flick phosphene, and * sound phosphene.
