Visual evoked potential changes in pre-diabetics, type 2 diabetics and normal subjects
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2018, Vol 5, Issue 3
Abstract
Introduction Diabetes mellitus type 2 is the most common metabolic disorder and diabetic retinopathy is the leading cause of blindness Persistent hyperglycemia leads to damage of microvasculature supplying the retina and optic pathway Visual evoked potential is the most commonly used test to evaluate the integrity of visual pathway The purpose of the study is to compare the visual evoked potential latency and amplitude between the prediabetes diabetes and normal controlsMaterials and Methods There were three groups in the study with 23 patients in each group prediabetic group diabetic group and controls Group was made based on fasting blood sugar levels Pattern visual evoked potential was measured in all the groups by connecting scalp electrodes according to 1020 International electrode placement system Latency and amplitude of N75 P100 and N145 were measured and used for statistical analysisResults All the parameters individually were compared between three groups using ANOVA test There was no statistical difference between latencies and amplitude all the three parameters N75 P100 N145 in all the three channels O1NE O2 NE OzNE in all the three groupsConclusion There is no differences in the visual evoked potential latency and amplitude in the between prediabetics diabetes and controls Keywords Visual evoked Potential Diabetic retinopathy Prediabetes P100 N75 N145
