Pupil perimetry.


The pupillomotor and visual sensitivity were compared at the same 76 points across the 30 degrees field. The timing and amplitude of pupillary contractions to focal light stimuli were recorded using a computerized infrared pupillometer linked to a Humphrey automated perimeter. Pupil perimetry and standard threshold perimetry showed matching defects in the visual field of patients with ischemic and compressive optic neuropathy, but not in patients with primary open-angle glaucoma. Patients with isolated occipital strokes showed matching homonymous visual and pupillary fields, suggesting a suprageniculate influence upon the pupillary light reflex. Pupil perimetry is a useful objective form of perimetry and can be used to compare the effect of disease on the visual and pupillary pathways.
