Official title
Effects of a Novel Dietary Supplement on Visual Function in Patients With Diabetes With and Without Early Diabetic Retinopathy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will evaluate the effects of a novel multi-component dietary supplement on the visual function and retinal structure of patients with diabetes with both no diabetic retinopathy and mild to moderate diabetic retinopathy. This is a placebo-controlled trial and neither subjects nor examiners will know if any given subject is taking active supplement or placebo. The hypothesis is that the supplement will improve visual function and retinal structure in subjects on active supplement
