[Qingfeng Internal Obstruction]
Xijiang Yue (Moon over the West River):
What are the ocular manifestations of Qingfeng internal obstruction? There is neither pain nor itching, allowing it to progress unchecked. The pupil appears calm and unblemished, as if unaffected by disease, yet I am plagued by vertigo. Gradually, visual disturbances such as floating spots (metamorphopsia) appear above and below; later, dimness worsens with fatigue. Taking Huanjing San (Restore Vision Powder) is not effective; it should be combined with Lingyangjiao San (Antelope Horn Powder).
This condition arises from Kidney deficiency and exhaustion. It is difficult to treat. Suitable prescriptions include Huanjing San (Restore Vision Powder), Zhen Gan San (Settle Liver Powder), and Er Di San (Two Earths Powder).

[Ganxu Que Mu - Liver Deficiency Night Blindness]
Zhegu Tian (Partridge Sky):
Night blindness (Que Mu) has been distressing since birth; when children suffer from this, it is named "Gan" (malnutrition-related eye disease). This disease is caused by Liver deficiency and exhaustion. At the time of lighting lamps, one cannot see clearly. Visual hallucinations or floaters arise, or there is headache. After many years, it unexpectedly leads to bilateral blindness. When first afflicted, medication must be taken immediately; neglecting medical treatment due to lethargy will result in bilateral blindness.
This is caused by Liver deficiency and exhaustion. If prolonged, it becomes difficult to treat. Suitable prescriptions include Sanhua Wuzi Wan (Three Flowers and Five Seeds Pill), Zhen Gan San (Settle Liver Powder), Huanjing San (Restore Vision Powder), and Renshen San (Ginseng Powder).

[Gaofeng Que Mu - High Wind Night Blindness]
Zhegu Tian (Partridge Sky):
The syndrome of Gaofeng Que Mu (High Wind Night Blindness) is similar to the previous ones, but there are differences in presentation. One becomes unable to see clearly upon reaching dusk. After years, the pupil resembles a round pearl. The signs of Gaofeng have been passed down through ancient and modern times. Do not indulge in rich flavors or be entangled by lust. Divine medicines can cure it, making one like a happy immortal on earth.
This is caused by Liver deficiency and exhaustion. This disease is difficult to treat. Suitable prescriptions include Sanhua Wuzi Wan (Three Flowers and Five Seeds Pill), Zhen Gan San (Settle Liver Powder), Huanjing San (Restore Vision Powder), and Mengling San (Dream Spirit Powder).

[Ganxu Que Mu An - Liver Deficiency Night Blindness with Dimness]
Zhegu Tian (Partridge Sky):
To understand Liver deficiency, one must recognize the cause of the illness: both distance and near vision are unclear. Objects before the eyes are invisible, obscured like smoke; one object appears as two (diplopia). With Liver deficiency heat, calm the mind. Taking Bogan San (Tonify Liver Powder) is as effective as divine intervention. Self-care and protection are essential; do not let mental exhaustion lead to further blindness.
This is caused by Liver Qi deficiency and exhaustion. It is difficult to treat. Suitable prescriptions include Sanhua Wuzi Wan (Three Flowers and Five Seeds Pill), Zhen Gan San (Settle Liver Powder), Mijing Wan (Mirror Polishing Pill), Huanjing San (Restore Vision Powder), and Er Di San (Two Earths Powder).
