Brief Summary

Diabetic Retinopathy is the leading cause of blindness in the world. Previous studies have documented beneficial effects of physiologic administration of pulsatile insulin on a variety of diabetic complications such as nephropathy, hypertension, glycemic control, etc. Similar pathogenetic mechanisms have been postulated for diabetic retinal disease. This study examines the effect of pulsatile insulin on patients with varying stages of diabetic retinal disease.

ACTIVE COMPARATOR

Patients with diagnosed Diabetic Retinopathy are enrolled as treated with pulsatile intravenous insulin or as a control patient with weekly treatment sessions. Baseline and quarterly fundus photography is performed to measure and monitor progress.

Procedure: Pulsatile IV InsulinProcedure: Effects of Pulsatile IV Insulin on Diabetic Retinopathy

1

NO INTERVENTION

Patients diagnosed with Diabetic Retinopathy are enrolled as control patients that do not receive the pulsatile intravenous insulin therapy. Control patients come into the center receive baseline fundus photography and quarterly fundus photography to measure progress and outcomes of diabetic retinopathy and are compared to the patients who receive pulsatile intravenous insulin therapy.

Interventions

Intravenous Insulin is provided in a pulsed manner based upon weekly physician orders the amount of insulin provided is dependent on patients level of insulin resistance.

2

Control Patients are not given pulsatile intravenous insulin therapy during the study.
