Pupil cycle time in noncompressive optic neuropathy.
Pupil cycle time was found to correlate with the clinical findings in 24 patients with noncompressive optic nerve pathology, including 11 cases of multiple sclerosis. Furthermore, subclinical multiple sclerosis was detected by the prolongation of pupil cycle time and was confirmed by visual evoked potential analysis. There was a correspondence between dynamics in the clinical findings and the pupil cycle time in two cases of multiple sclerosis that were followed up.
