Primary Outcome Measures:
  • Corneal endothelium cell number [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The study is a cross-sectional study. We compare a cohort of patients with DM to a cohort with no DM. We examine each patient and control once. We call time of appointment or examination for "at entry to study".


Secondary Outcome Measures:
  • Corneal endothelium morphology [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The size and hexagonality of the cells are analysed automaticly by computer recognizion.


Estimated Enrollment: 300
Study Start Date: June 2009
Estimated Study Completion Date: September 2010
Estimated Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
Diabetes Type II
Patients with type 2 Diabetes Mellitus
Control
Patients with no diabetes

Detailed Description:

Diabetes might influence the health of the corneal endothelium. Older studies have presented different results and the glycemic status of the patients have not been reported. In this study we examine the corneal endothelium morphology and central thickness in type II Diabetes Mellitus and normal subjects with modern specular microscopy. Each patient and control is examined once ("entry to study").
