Background: Dry eye disease is a chronic, progressive ocular disease characterised by ocular discomfort and is one of the most common ophthalmological disorders that affects people's lives.
Methods: This study investigated the clinical efficacy of anthocyanin oligomers (grape skin extract) for the treatment of dry eye. One hundred and eight patients with dry eye were randomly divided into placebo and treatment groups, each with 54 cases. The placebo group received maltodextrin (800 mg/day) and the treatment group received anthocyanin oligomers (800 mg/day). Clinical efficacy, clinical indices, and occurrence of adverse reactions were compared between the two groups.
Results: Anthocyanin oligomers were safe and effective in mild-to-moderate dry eye disease, improving the tear break-up time, intraocular pressure, ocular surface disease, and patient symptomatology.
Conclusions: The use of oral anthocyanin oligomers in the treatment of dry eye patients can enhance the therapeutic effect and improve the quality of life of patients while ensuring the safety of treatment, making this therapeutic option suitable for wider application.
