Progress in Experimental and Clinical Research of the Diabetic Retinopathy Treatment Using Traditional Chinese Medicine

摘要

Diabetic retinopathy (DR), one of the most common microvascular complications of diabetic mellitus, is currently the main cause of adult-acquired blindness. The pathogenesis of DR is complex and the current clinical application of various treatment methods cannot completely prevent the development of this disease. Many reports have been published regarding the treatment of DR with Traditional Chinese Medicine (TCM), which has received increasing attention from medical practitioners worldwide. Studies published between 1994 and April 2017 were collected from the CNKI, VIP, Medline and Web of Science databases, as well as from Chinese traditional books and Chinese Pharmacopoeia, subsequently obtaining more than 550 studies. Thereafter, the status quo of DR treatment using TCM had been summarized according to four aspects - compound formula therapy, Chinese herbal medicine extracts and monomer therapy, integrated traditional Chinese and Western medicine therapy, and Chinese medicine external treatment. According to the literature reviewed herein, TCM has had definite effects on the prevention and treatment of DR, especially when used in combination with modern medical methods. However, the lack of a unified standard on the syndrome differentiation of DR and the lack of support of evidence-based medicine theory in clinical practice have been consistent concerns in previous research studies and needs to be addressed in subsequent studies.
