Nutritional Supplements and Performance During Visual Field Testing (B3 Vitamin)


Brief description of study

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

Detailed Study 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.
