Discourse states: The formation of nebulae (membranous opacities) in the eyes, whether recent or chronic, is caused by wind pathogens and toxic heat accumulating within the zang-fu organs, rushing upward, and condensing without dissipating. The manifestations vary; thus, there are internal and external distinctions, with nebulae being either superficial or deep, treatable or untreatable. These details are recorded in detail in the *Longmu Lun* (Treatise on Dragon Wood). Vulgar practitioners of the world often employ methods such as hooking, cutting, needling, scissoring, moxibustion heating, and cauterization to seek temporary relief, unaware that if these methods are not used cautiously, they may lead to blindness. Generally speaking, diseases of eye nebulae can be treated by hooking, cutting, needling, scissoring, heating, and cauterization; some require medication alone; others require prior medication and washing/dropping, followed by surgical intervention. If one can thoroughly study the principles of medical classics, penetrate the examination of the six pulses, and understand the deficiency and excess of the zang-fu organs, then carefully observe and judge which cases are suitable for medication, which for dropping/washing, and which for surgical intervention, how could there be reckless injuries? Now, we briefly select the effective internal medications, followed by the agents for washing and dropping.
