ClinConnect Summary
This clinical trial is looking at whether certain supplements can help improve vision in adults with glaucoma, a condition that affects the eye and can lead to vision loss. The researchers want to find out if taking different forms of a substance called NAD (which is important for energy and cell health) can make a difference in how well glaucoma patients can see. Participants will be randomly assigned to take one of four different NAD supplements or a placebo (a non-active substance) every day for two weeks. They will undergo eye exams and provide blood samples before and after the study to see if these supplements improve their visual function and how they affect the levels of NAD in the blood.
To be eligible for this study, participants need to be at least 18 years old and have a diagnosis of glaucoma with specific vision and eye pressure requirements. They should not have other eye diseases or conditions that could interfere with the results. Throughout the study, their safety will be monitored closely. This research aims to understand whether boosting NAD levels can help improve vision in glaucoma patients and what changes occur in their blood during the process.
