The purpose for the study consists in the assessment of the role of Neurotidine® (citicoline oral solution) on the dopaminergic pathway and particularly its potential implications on psychophysical performance and quality of life. Other objectives are the assessment of the tolerability and safety of Neurotidine®.
Primary open angle glaucoma is a chronic progressive neurodegenerative disease and the only proven effective therapy involves reduction of intraocular pressure (IOP). Although treatment effect is quite large, a significant proportion of patients show disease progression with apparently controlled IOP. Given the similarities with other neurodegenerative diseases - particularly in the mechanisms of cell death -neuroprotective treatments have been tried also in glaucoma. Interesting results from experimental studies and weak evidence from human glaucoma trials have been published in recent years. Citicoline is one of the promising molecules with a putative neuroprotective action and has been tried on patients with a number of neurodegenerative diseases with encouraging results. Pilot studies on glaucomatous patients showed a possible effect of citicoline in reducing progression of visual field changes, though these findings need to be confirmed by larger randomized clinical trials. The aim of this randomized, double-masked, placebo-controlled, cross-over study is to test whether the intake of Neurotidine® (citicoline free acid in oral solution) can be associated with an improvement of quality of life in patients with glaucoma.

Each patient will be given the bottles for the first 3-month treatment period by the hospital pharmacist and will be asked to return them at the end of the period (3 months). Then the patients will be given the other bottles for the next phase of the study (3 months): these will contain placebo if the patient received Neurotidine® in the first phase of the study and vice versa. Again, the patients will be asked to return after 3 months with the study bottles and will be given the last set of bottles for the final phase of the study (3 months). Administration at a dosage of 10 ml in the morning.

The mean change of "intra-patient" global score of the Visual Functioning Questionnaire 25 (VFQ-25) after Neurotidine® vs placebo.
Primary outcome is based on the global score of the VFQ-25 questionnaire. Specifically, the VFQ-25 consists of a base set of 25 vision targeted questions. The global score derives from the summary of the scores deriving from each question. The total score has a minimum value "0" considered as the worst visual functionality, and the maximum value "100" considered as the better visual functionality.
Time frame: At 6 months compared to baseline
The change of other scores of the questionnaire: Visual Functioning Questionnaire 25 (VFQ-25).
Other score utilized in the study: general health, general vision, near and far activities, social, mental, role difficulties, etc.
Time frame: Up to 9 months compared to baseline
The change of other scores of the questionnaire: Short Form Health Survey - 36 items (SF-36).
Other score utilized in the study: general health, general vision, near and far activities, social, mental, role difficulties, etc.
Time frame: Up to 9 months compared to baseline
The safety and tolerability of Neurotidine®.
The safety and tolerability of Neurotidine® will be detected on the basis of possible adverse events. In particular, they will be documented in the CRF. Possible adverse events will be communicated directly by the patient and/or detected by the Investigator during the medical examination.
Time frame: Up to 9 months compared to baseline
