What this trial studies

This study investigates whether a combination of vitamins B6, B9, B12, and choline can protect the eyes of individuals with glaucoma and slow down vision loss. Participants aged 18 and older with primary open-angle glaucoma or pseudoexfoliation glaucoma will be randomly assigned to receive either the vitamin supplement or standard glaucoma care for one year. The study aims to assess the vitamins' potential to support retinal cell function and overall eye health. Participants will attend five clinic visits throughout the study period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with primary open-angle glaucoma or pseudoexfoliation glaucoma.

Not a fit: Patients with severe visual field damage or other conditions affecting retinal function may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could help preserve vision and improve the quality of life for glaucoma patients.

How similar studies have performed: While the use of vitamin supplementation in glaucoma is a novel approach, similar studies have shown potential benefits of nutritional support in eye health.
