Official title
The Effects of an Antioxidant Formulation on Intraocular Pressure, Ocular Perfusion Pressure, Retrobulbar, Retinal Capillary and Choroidal Blood Flow
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The objective is to evaluate the effects of an antioxidant formula versus placebo on ocular blood flow in a randomized double-blind, crossover design. Based upon preliminary data, it is hypothesized that a dietary supplement containing a variety of ingredients with antioxidant properties will, compared to placebo, increase ocular perfusion pressure, retrobulbar, retinal capillary and choroidal blood flow, and maintain these effects over the course of the treatment period.
