Objectives: To explore the various pharmacological actions and the molecular mechanisms behind them by which Chinese herbs tend to lower the risk of developing microvascular diabetic complications in retina and prevent its further progression.
Key findings: Several Chinese herbs, indeed, elicit potent anti-inflammatory, antioxidant, anti-angiogenic, anti-apoptotic, peroxisome proliferator-activated receptor-gamma receptor agonistic, platelet-activating factor antagonistic, aldose reductase inhibitory and various other beneficial pharmacological activities, required to counteract the pathological conditions prevalent in retina during diabetes.
Summary: Chinese herbs can potentially be used for the treatment/prevention of diabetic retinopathy owing to the virtue of numerous properties by which they alleviate several hyperglycaemia-induced pathological occurrences in retina. This would provide a natural and safe therapy for diabetic retinopathy, which currently is clinically limited to destructive techniques like laser photocoagulation and vitrectomy.
