Safety and Efficacy of Anti-Oxidants and Anti-inflammatory Agents in Glaucoma and Diabetic Retinopathy

This study is a multi-armed protocol designed to evaluate the safety and efficacy of two different combinations of nutritional supplements (study drug) (Glauco-Health and Glauco-Select) chosen for their potential to protect retinal ganglion cells against oxidative stress, low-grade inflammation, and mitochondrial dysfunction in patients with open-angle glaucoma and diabetic retinopathy. Oxidative stress and retinal cellular dysfunction will be measured using a Retinal Metabolic Analyzer (RMA) in this randomized, single center, double masked study. Patients with glaucoma will be divided into three treatment arms randomized to receive either Glauco-Health, Glauco-Select, or placebo.

This investigation is using over the counter supplements. The investigation is intended only to evaluate their effect on the structure or function of mitochondria as it relates to the autofluorescence imaging being conducted in the study. They are not being studied to evaluate their ability to diagnose, cure, mitigate, or treat disease. These ingredients in these combinations of nutritional supplements have also been reported beneficial in diabetic retinopathy. Patients with diabetic retinopathy will be added later as an additional arm and an amendment to this effect will be submitted when that portion of the study is ready to be initiated. That amendment will include background material, appropriate inclusion and exclusion criteria, informed consent, and references. At the current time, only the glaucoma proposal and glaucoma patients will be enrolled according to this submitted protocol.
