Nicotinamide and pyruvate help improve vision in glaucoma patients: JAMA
USA: A new study reveals that a combination of nicotinamide and pyruvate significantly improved visual function in the short term.

USA: A new study reveals that a combination of nicotinamide and pyruvate significantly improved visual function in the short term. The results confirm previous experimental research suggesting a role for these agents in neuroprotection for people with glaucoma and confirming the need for long-term studies to establish their usefulness in slowing progression. The findings of this study were published in the journal JAMA Ophthalmology on 18th November 2021.
This study was conducted by Carlos Gustavo De Moraes and the team with the objective to see if a combination of nicotinamide and pyruvate can enhance retinal ganglion cell activity in people with glaucoma, as evaluated by routine automated perimetry.
This was a phase 2 randomized, double-blind, placebo-controlled clinical study where 197 participants were evaluated for eligibility at a single academic institution. 42 patients with treated open-angle glaucoma and moderate visual field loss in at least one eye were chosen and randomized. The study included 32 participants who finished it and were included in the final analysis. The average (standard deviation) age was 64.6 (9.8) years. Twenty-one of the twenty-one participants (66%) were female.
Data on participant race and ethnicity were acquired by self-report to verify that the distribution mirrored that seen in clinical practice in the United States, but are not disclosed here to safeguard patient privacy. For this work, patients were recruited in April 2019 and were followed up on until December 2020. The data was examined from January through May of 2021.
The results were seen as; patients with manifest open-angle glaucoma treated with a combination of nutritional supplements (nicotinamide and pyruvate) experienced a statistically significant improvement in visual function based on the number of improving test locations on SAP compared to the placebo group in this placebo-controlled clinical trial. Furthermore, the rate of change of the visual field PSD was considerably different, indicating that global perimetric sensitivity has improved.
In conclusion, nutritional supplementation with high doses of nicotinamide and pyruvate can increase visual field sensitivity in treated glaucoma patients with mild functional loss in the near term. The development of novel neuroprotective medicines for glaucoma patients may be enabled by the selection of drugs targeting NAD and bioenergetic capability to boost cellular resilience. A clustered visual field testing paradigm will most likely be effective for assessing future neuroprotective drugs.
