Major Phytochemicals with Therapeutic Potential in the Treatment of Diabetic Retinopathy. Rev Cubana Oftalmol [online]. 2022, vol.35, n.4  Epub 01-Dic-2022. ISSN 1561-3070.

Type 2 diabetes mellitus represents one of the main public health problems worldwide today. Among the main complications generated by this disease is diabetic retinopathy, which can lead to permanent vision loss. For this reason, research on treatments for this pathology is increasing. This is why treatments based on chemicals obtained from medicinal plants are widely investigated as they could provide a safer, less costly and less toxic alternative to standard medicine for the treatment of this eye disease of high incidence worldwide. The aim of this study was to identify the main phytochemicals with potential to be used as treatment for diabetic retinopathy. In order to achieve this purpose, a review of the literature published between January 2017 and June 2021 was conducted using the WOS, PUBMED and Scopus databases in English and Spanish, in order to compile updated scientific evidence on the use and impact of phytochemicals in diabetic retinopathy. Several families of useful phytochemicals were identified. Among these, the most common were those of phenolic origin, although less common were also found carotenoids, terpenes and blends consisting of various plant species and phytochemicals. Their mechanisms of action were also identified, the most common being suppression of vascular endothelial growth factor-mediated neovascularization, protection and restoration of the blood-retinal barrier, reduction in reactive oxygen species activity and anti-inflammatory effect. Given the evidence regarding the usefulness of phytochemicals for the treatment of diabetic retinopathy, further research should be conducted.
