- Moore's lightning streaks
- The eponym Moore's lighting streaks refers to a subclass of the group of *phosphenes characterized by brief, vertical flashes of light in the temporal field of one eye, typically occurring in the dark, and typically elicited by acceleration of the eye or the head. Moore's lightning streaks are traditionally classified as *entoptic phenomena. They tend to be attributed to vitreous traction. The eponym Moore's lightning streak was coined in or shortly before 1941 by the American ophthalmologist Frederick Herman Verhoeff (1874-1968), in honour of his British colleague Robert Foster Moore (1878-1963), who had described the concomitant phenomenon in 1935. Conceptually and phenomenologically, Moore's lightning streaks are considered closely akin to the * fiery rings of Purkinje and the * flick phosphene.ReferencesMoore, R. (1935).
