Can a daily drink help slow Glaucoma's vision loss?

This study tested whether a daily oral solution containing citicoline and nicotinamide (Kron) could improve eye and brain function in people with open-angle glaucoma. Thirty patients with moderate glaucoma were randomly assigned to receive either the solution or no treatment for three months. Researchers measured changes in electrical signals from the retina and visual cortex, as well as standard vision tests, to see if the solution had a protective effect.
