Abstract

STUDY DESIGN-PROSPECTIVE COMPARATIVE STUDY
PURPOSE-TO COMPARE PRE AND POST MYDRIATIC PUPIL SIZE IN DIABETICS VS NON DIABETICS
METHODS-THE STUDY INCLUDED 63 DIABETIC AND 63 NON DIABETIC PATIENTS. PUPILLARY SIZE OF ALL PATIENTS WERE MEASURED BEFORE DILATATION AND THEN MYDRIATIC EYE DROPS WERE INSTILLED FOLLOWED BY MEASUREMENT OF PUPIL SIZE USING PUPIL GAUGE. SIZE OF PUPIL WERE COMPARED BETWEEN DIABETICS AND NON DIABETICS.
RESULTS-THE PRE MYDRIATIC PUPIL SIZE OF 1-2MM WAS FOUND ONLY IN DIABETIC PATIENTS (38%) (P<0.05) WHEREAS 39 DIABEIC PATIENTS (61.9%) AND 63 NON DIABETICS (100%) HAD PRE MYDRIATIC PUPIL SIZE 3-4MM (P<0.05). 43 DIABETIC PATIENTS (68.3%) AND 13 NON DIABETIC PATIENTS (20.6%) HAD POST MYDRIATIC PUPIL SIZE 6-7MM (P<0.05) WHEREAS 20 DIABETICS (31.7%) AND 50 NON DIABETICS (79.4%) HAD POST MYDRIATIC PUPIL SIZE 7-8MM (P<0.05).
CONCLUSION-PRE AND POST MYDRIATIC PUPILLARY SIZE WERE SMALLER IN DIBETIC PATIENTS AS COMPARED TO NON DIABETIC PATIENTS.
