Methods: In this randomized, prospective, doubleblind study, 29 OAG patients were enrolled. Fifteen patients (Citicoline Group, 15 eyes) received Citicoline oral solution (Neurotidine®, 500 mg/day), and 14 patients (Placebo Group, 14 eyes) received placebo for 12 months. Visual field (VF), pattern electroretinogram (PERG), visual evoked potentials (VEP), and Retinocortical Time (RCT) were assessed at baseline and after 6 and 12 months. Brain Diffusion Tensor Imaging (DTI)-Magnetic Resonance Imaging (MRI) was performed at baseline and at 12 months. Results: PERG, VEP, and RCT baseline values were comparable between groups (p > 0.01) at baseline. After 12 months of Citicoline treatment, significant (p \u003C 0.01) increases in PERG P50–N95 and VEP N75-P100 amplitudes, and significant shortening of PERG P50, VEP P100 implicit times and RCT were observed. VEP implicit times shortening significantly correlated with the changes in VF Mean Deviation, and RCT shortening was associated with changes in DTI-MRI metrics in the lateral geniculate nucleus and on optic radiat","cbCaiuV70HZqhu7c","https://ap.wps.com/l/cbCaiuV70HZqhu7c","pdf",3572917,25,"English","# Abstract\n# Objectives and Methods\n## Study design\n## Outcome measures\n# Results\n## Electrophysiology\n## Imaging correlations\n# Conclusions\n# Introduction","[{\"question\":\"What was the purpose of this study on Citicoline in open-angle glaucoma?\",\"answer\":\"To evaluate how 12 months of Citicoline oral solution affects retinal function and neural conduction along the visual pathways in open-angle glaucoma patients.\"},{\"question\":\"How was Citicoline compared with placebo in the trial?\",\"answer\":\"In a randomized, prospective, double-blind study, 15 patients received Citicoline oral solution (500 mg/day) and 14 received placebo for 12 months.\"},{\"question\":\"What outcomes improved after 12 months of Citicoline treatment?\",\"answer\":\"PERG and VEP showed increased amplitudes, and implicit times for PERG P50 and VEP P100 were significantly shortened, along with Retinocortical Time shortening, with no significant changes in the placebo group.\"}]","Citicoline Oral Solution Induces Functional Enhancement and Synaptic Plasticity in Patients with Open-Angle Glaucoma - Research Findings | PDF",1790761834,63]
