Abstract: Prof. LYU Haijiang believes that the disease location of anterior ischemic optic neuropathy (AION) is in the eye connector. Its etiology and pathogenesis are constraint of collaterals, constraint and blockage of sweat pore, and depression or annihilation of eye spirit of the eye connector caused by constraint of qi and blood,phlegm- heat obstructing the upwards,or qi- blood depletion. Influenced and inspired by the theory of sweat pore,the theory of collateral diseases,the theory that eye diseases are often induced by constraint and the application idea of worm medicine in Chinese medicine, Prof. LYU inherits and develops the academic thought of “method of resolving constraint and removing stagnation” of Prof. ZHANG Wangzhi, a famous ophthalmologist. With the combination of many years of his clinical experience, Prof. LYU believes that AION should be treated by the methods of resolving constraint and removing stagnation as well as unblocking the orifices to to improve vision in the early phrase. He is good at syndrome differentiation and treatment based on Kaiyu Daozhi Basic Prescription,and reasonably combines with worm medicine like Pheretima, Hirudo and Bombyx Batryticatus to facilitate expelling stasis, unblocking the collaterals, unblocking the orifices, and smoothing sweat pore. In the middle and late phrases of AION,Prof. LYU often reasonably combines with herbs that can boost the liver and kidney and improve vision like Lycii Fructus based on the method of resolving constraint and removing stagnation as well as unblocking the collaterals and the orifices, and modifies them according to different symptoms, which achieved ideal curative effect.
