A Longitudinal Study To Identify Early Non-invasive Ocular Markers of Diabetic Complications

This is a human subject study looking at the complications arising in newly diagnosed diabetic patients using non-invasive measures, optical coherence tomography (OCT) and corneal confocal microscope (CCM), indicative of peripheral neuropathy and diabetic retinopathy. Through the use of these devices we would like to determine the onset of corneal nerve fiber alterations and retinal thinning in newly diagnosed diabetics. This information could help investigators find early and reversible biomarkers to target for therapeutic options.
