History of Changes
  Purpose

Diabetes mellitus is becoming a global epidemic. There is a need to devise a non invasive method for detection of diabetes and its related complication. Tear proteins are easy to collect causing no harm to a patient and different studies indicate that tear proteins of diabetic patients are significantly different from non diabetic population. This difference in the composition of tear proteins become more pronounced with advancement of diabetic retinopathy.

Estimated Enrollment: 350
Study Start Date: January 2009
Estimated Study Completion Date: June 2011
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
Non diabetic
Normal age and sex matched population
Grade 1
Diabetic population with no retinopathy or Mild non proliferative diabetic retinopathy
Grade 2
Moderate non proliferative diabetic retinopathy
Grade 3
Severe non proliferative diabetic retinopathy
Grade 4
Proliferative diabetic retinopathy and advanced diabetic eye disease

Detailed Description:

Diabetes mellitus causes a significant alteration in tear proteins. If we analyze tear proteins by means of electrophoresis, HPLC, and mass spectroscopy.

We can find different type of tear proteins in different grades of diabetic retinopathy these biomarkers can help in mass screening , diagnosis and management of diabetic population.
