Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study seeks to test whether these over-the-counter nutritional supplements have an impact on patients' performance during visual field testing.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Glaucoma is the leading cause of irreversible blindness worldwide. The most important test to detect progression is visual field testing. Visual field testing is the reference standard to measure visual function in glaucoma. It is called called standard automated perimetry (SAP). However, this test is very subjective, often unreliable, and variable. One of the main causes of unreliable tests is the lack of attentiveness or concentration during the test. Previous studies have shown that listening to Mozart or taking vitamin B12 can improve the reliability of this test. Recent studies have suggested that over-the-counter medications such as nicotinamide (vitamin B3) and pyruvate can also improve the performance during this test. This can ultimately reduce costs due to repeated testing and increase doctor's certainty when analyzing the results of this test.

Nicotinamide and Pyruvate (N&P)

This group will receive two separate sets of tablets containing 3 x 1000 mg of Vitamin B3 (nicotinamide) and 2 x 1500 mg of Pyruvate.

Group Type ACTIVE_COMPARATOR

Vitamin B3

Intervention Type DIETARY_SUPPLEMENT

3 tablets of 1000 mg each will be administered orally.

Placebo

This group will receive an equal number of tablets as the N\&P group.

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type DIETARY_SUPPLEMENT

Tablets will look identical to the supplements and the number of tablets will equal the amount of supplements provided.
