Retinal Function in Relation to Long Term Changes in the Glucose Level

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified September 2009 by Glostrup University Hospital, Copenhagen.
Recruitment status was:  Recruiting

Glostrup University Hospital, Copenhagen Identifier:

The purpose of this study is to measure the amplitude and implicit time of electroretinogram (ERG), darkadaptation and the calibre of retinal vessels before and after optimized medical treatment of diabetic individuals (a lower blood glucose level) over a period of 12 months. Newly diagnosed type 1 and type 2 diabetics as well as dysregulated type 1 and type 2 diabetic individuals will be included. Retinal vessel calibre measurements will be used as an estimation of changes in the retinal perfusion.
