  • Abstract
  • Look Inside

Pupillary escape phenomenon is a well-known sign in patients with disorders of anterior visual pathways, especially in those with optic nerve dis-eases. Day blindness is also known to be another sign of optic neuritis. This sign was analyzed by Enoch in 1978.

We examined these two phenomena in about 30 patients with optic nerve diseases. Pupillary escape phenomenon was measured by infrared television iriscorder during stimulation by relatively intense light. Visual fatigue phenomenon was also measured as the temporal change of CFF (Critical Flicker-fusion Frequency) by subjective method.
