Clinical Trial Summary

To evaluate the long-term effects of oral citicoline, vitamins A, B, C and E, and blackcurrant therapy in patients with primary open-angle glaucoma (POAG) using optical coherence tomography (OCT), OCT angiography (OCTA) and microperimetry parameters.

Description:

AIMS: To evaluate the long-term effects of oral citicoline, vitamins A, B, C and E, and blackcurrant therapy in patients with primary open-angle glaucoma (POAG) using optical coherence tomography (OCT), OCT angiography (OCTA) and microperimetry parameters. METHODS: Fifteen patients with POAG (treated group) received one soluble liquid sachet daily for 20 days a month of a complementary dietary supplement containing in fixed combination citicoline, vitamins A, B, C, and E, and blackcurrant for 1 year. Fifteen age-matched subjects affected by POAG were given a placebo and served as a control group. The patients underwent best corrected visual acuity (BCVA), Goldmann applanation tonometry, microperimetry examination, OCT, and OCTA at the beginning of the study and then at 1, 6 and 12 months.
