Treatment of Retinal Vascular Diseases Based on Theory of"Hidden Pathogen Dam-aging Collaterals"
Retinal vascular diseases(RVD)refer to a group of retinal vascular disorders,including diabetic reti-nopathy,retinal vein occlusion,and retinal artery occlusion,often accompanied by macular edema and neovascularization.RVD is attributed to a deficiency of vital Qi and dysfunction of the internal organs,which leads to the gradual accumulation of pathological products such as blood stasis,phlegm,dampness,and heat.These pathological factors circulate with the Qi and blood,eventually becoming lodged in the retinal collaterals.Over time,they transform into pathogens,damaging the ret-inal collaterals.The clinical characteristics of RVD,including insidious onset,severe progression,complex etiology,recur-rent nature,and difficulty in healing,align with the traditional Chinese medicine(TCM)concept of"hidden pathogen".The disease begins with"deficiency of vital Qi and hidden pathogens",and the key to its progression is"hidden pathogens damaging collaterals".In the later stages,the persistence of these hidden pathogens leads to repeated episodes.Therefore,the general treatment principle for RVD should be to"nourish vital Qi,dispel pathogens,detoxify,and unblock the collater-als".Different detoxification methods should be employed at different stages of disease progression.Additionally,insect-based and vine-based medicines may be used appropriately and lead medicine into collaterals,targeting the pathogen sites.
