Primary | Corneal small nerve fiber damage | Estimate corneal small nerve fiber damage in young T1DM subjects and compare the results to healthy controls using corneal confocal microscopy (CCM). This will be done by examining the cornea via confocal microscopy and obtaining images. These images will be evaluated looking at how many nerves there are, how they branch, and how long they are). | Assessed one time per subject during study (study completed over 3 years) | |
Primary | Normative values for corneal confocal microscopy (CCM) | Obtain much needed normative values for CCM in adolescents and intraepidermal nerve fiber density from skin biopsies in subjects with type 1 diabetes. This will be done by obtaining a small biopsy of skin and looking at the number of nerve fibers in the outer layer of the skin. | Assessed one time per subject during study (study completed over 3 years) | |
Secondary | Serum biomarkers - leptin | Measuring serum biomarkers (blood levels) leptin. In participants with diabetes, comparing the blood level measurements of those with neuropathy vs. those without neuropathy. | Assessed one time per subject during study (study completed over 3 years) | |
Secondary | Serum biomarkers - TNF Alpha | Measuring serum biomarkers (blood levels) Tumor Necrosis Factor (TNF) Alpha. In participants with diabetes, comparing the blood level measurements of those with neuropathy vs. those without neuropathy. | Assessed one time per subject during study (study completed over 3 years) | |
Secondary | Serum biomarkers - fibrinogen | Measuring serum biomarkers (blood levels) fibrinogen. In participants with diabetes, comparing the blood level measurements of those with neuropathy vs. those without neuropathy. | Assessed one time per subject during study (study completed over 3 years) |
