COMPARATIVE ASSESSMENT OF SIZE OF THE PUPIL IN SUBJECTS WITH MIGRAINE AND PHOTOPHOBIA TO NORMAL SUBJECTS AND CORRELATION OF SEVERITY OF HEADACHE TO PUPIL SIZE

Abstract

Background: Abnormalities in the size of the pupil are a reason for migraine in photophobia in subjects. However, existing
literature data is scarce concerning the grade of severity of migraine and the relation of pupil size in affected subjects.
Aim: The present study aimed to comparatively assess the size of the pupil in subjects with migraine and photophobia to
normal subjects and the correlation of the severity of headache to pupil size.
Methods: The present study assessed 100 subjects having migraine with photophobia and were compared to 100 control
subjects that had no history of headaches and were gender and age-matched. The size of the pupil was assessed using IOL
Master 700 in all the subjects. The severity of the headache was assessed using the MIDAS (Migraine disability assessment)
test questionnaire and MIDAS grades from 1 to 4 depicting minimal disability to severe disability in all the subjects. Pupil
size was compared in all the grades.
