  • Abstract
  • Look Inside

Three patients with unilateral tonic pupil were investigated for pupillary light reflex under open-loop photic stimulus.

Following 15 minutes dark adaptation, successive 5 pupillary light reflexes were measured alternative-ly on both eyes with adequate rest by the use of a new infrared videopupillogram. The videopupil-logram was developed by one of us (Utsumi) which could elicit the light reflex by the photie stimulus under open-loop condition. The effects of tonic pupils on each pupillary parameters (Fig.1) were obtained from the following formula:

Amplitude of effect=20 log (tonic pupil/normal pupil) (db).
