Five groups were used in the current study: standard chow diet (SCD), HFrFSD, nebivolol, tadalafil, and their half doses combination. At the end of the experiment, markers of obesity and metabolic changes were measured; moreover, changes in retinal oxidative stress, vascular reactivity, apoptosis, fibrosis, and angiogenesis markers.

Both nebivolol and tadalafil did not cause significant changes in the markers of obesity, carbohydrate, and lipid metabolism, while they significantly reduced retinal tissue histopathological and molecular changes. Interestingly, the half-dose combination of nebivolol and tadalafil significantly reduced fasting blood glucose levels and insulin resistance compared with the HFrFSD group without affecting obesity markers and lipid metabolism and showed higher protective effects against retinopathy compared with the full dose individual treatments.

However, chemotherapy has several disadvantages, mainly manifested in severe side effects, limited efficacy, and the tendency to develop drug resistance.
