Pupillography as Screening Tool for Brain Insulin Resistance

Summary

Cerebral insulin action is important in the regulation of whole body glucose metabolism. However, the cerebral insulin action differs between individuals - there is a so called cerebral insulin resistance. The influence of central insulin action on peripheral metabolism seems at least partially mediated via the autonomous nervous system. A noninvasive method to measure autonomic function is the pupillography. The aim of the study is to find out whether pupillography can be used to assess central insulin activity. Thus, pupillography will be performed in 30 normal weight and 30 overweight subjects before and after application insulin intranasally.
