Bedeutung von Citicolin bei der Glaukomerkrankung

BACKGROUND: In recent years, many experimental and clinical studies have shown that in glaucoma, neuronal degeneration occurs not only at the level of the retina and optic nerve, but also along the entire visual pathway and the brain. OBJECTIVE: This article presents the neuroprotective effects of citicoline and their mechanisms in glaucoma disease. MATERIALS AND METHODS: The relevance of citicoline is explained against the background of neuroanatomy, neuroimaging, and the pathogenesis of glaucoma. Data from experimental and clinical studies are presented and a conclusion is drawn for clinical application. RESULTS: Citicoline has a neuroprotective effect via mechanisms relevant to glaucoma. The neuroprotective effect of citicoline in open-angle glaucoma can be demonstrated functionally and morphologically. It is independent of the glaucoma damage and intraocular pressure, and usually occurs only after 1 year. The effects of oral citicoline occur at a daily dose of 500–1000 mg. Citicoline can be taken permanently or in cycles. No side effects occurred in the studies when taking citicoline. Citicoline can improve cognitive performance and thus treatment adherence as well as quality of life in glaucoma patients. CONCLUSION: This relatively old nootropic drug, which is now marketed as a food supplement, seems to be a valuable addition to conventional treatment and also a rational option for prophylaxis of open-angle glaucoma.
