It is believed that wind,heat(fire),dampness and deficiency are the main pathological factors of herpes simplex keratitis(HSK),which is divided into the attack phase and intermittent phase for the differentiation and treatment.In the early attack phase,liver meridian wind-heat or intense liver and gallbladder fire are the key pathogenesis;for the for-mer syndrome,Qufeng Sanre Jiedu Formula(祛风散热毒方)is often used to scatter wind and clear heat,remove nebula to improve vision,while for the latter,Longdan Xiedu Formula(龙胆泻毒方)is recommended to clear and drain liver and gallbladder,remove nebula to improve vision.In the middle attack phase,internal accumulation of dampness and heat is the key pathogenesis,for which Sanren Jiedu Formula(三仁解毒方)is commonly used to clear heat and remove dampness,re-move nebula to improve vision.In the late attack phase,yin deficiency and internal heat are the key pathogenesis,and Ziyin Tuiyi Mingmu Formula(滋阴退翳明目方)is commonly used to enrich yin and subdue fire,remove nebula to improve vision.In the intermittent phase,deficiency of both qi and yin,and internal latent residual heat are the key pathogenesis,for which Yiqi Yangyin Quqie Formula(益气养阴祛邪方)is recommended to boost qi and nourish yin,remove nebula to improve vision.Simultaneously,attention should be paid to the combined application of western medication,ultrasonic atomi-zation eye smoke treatment with traditional Chinese medicine,dietary therapy,traditional Chinese medicine exercise and health-preserving techniques,so as to promote the improvement of HSK and prevent recurrence.
