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

Condition or disease Intervention/treatment Phase
Visual Field Defect, Peripheral Glaucoma, Open-Angle Dietary Supplement: Vitamin B3 Dietary Supplement: Pyruvate Dietary Supplement: Placebo Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Active Comparator: 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.
Dietary Supplement: Vitamin B3
3 tablets of 1000 mg each will be administered orally.
Other Name: B-3 Nicotinamide

Dietary Supplement: Pyruvate
2 tablets of 1500 mg each will be administered orally.
Other Name: Calcium Pyruvate

Placebo Comparator: Placebo
This group will receive an equal number of tablets as the N&P group.
Dietary Supplement: Placebo
Tablets will look identical to the supplements and the number of tablets will equal the amount of supplements provided.

Primary Outcome Measures :
  1. Change in 24-2 visual field test [ Time Frame: Up to 20 weeks ]
    Changes in 24-2 visual field results based upon point-wise and global metrics before and after intervention, and between treatment and placebo groups will be compared.

Secondary Outcome Measures :
  1. Change in Montreal Cognitive Assessment (MoCA) scores [ Time Frame: Up to 20 weeks ]
    Montreal Cognitive Assessment (MoCA) score before and after intervention and correlate these changes with those seen on visual field tests will be compared. The Montreal Cognitive Assessment (MoCA) is a brief 30-question test that assesses different types of cognitive abilities. Scores on the MoCA range from zero to 30, with a score of 26 and higher generally considered normal.
