暴盲，是指突然失明、看不见东西。导致这种病的因素有三种：一是阳气孤弱（阳寡），二是阴精孤立（阴孤），三是神气离散（神离）。这属于气机痞塞、上下格拒的病症。
因损伤阳气而发病的，多是因为愤怒暴躁，纵欲饮酒，嗜好辛辣，或者久病、热病、痰火内盛的人得了此病，症状表现为烦躁、便秘、口渴。
因损伤阴精而发病的，多是因为贪恋色欲，或者因为悲伤哭泣所致。患病时表现类似中风或中寒的发作。
因损伤神气而发病的，多是因为思虑过度，用心无度，忧伤至极，或者惊恐失措的人得了此病。患病后此人神情痴呆，发病时的状态如同痴傻。
临床上屡见阴虚水少之人，在头风、痰火引起的眩晕发作之后，醒来便看不见东西。若能注意保养，也有不治疗而自愈的情况。
对于气大虚者，急需服用大剂量的人参膏。对于血虚者，用大剂量的黄芪、当归煎汤，调服人参膏。
对于患湿邪者，以白术为君药，黄芪、茯苓、陈皮为臣药，附子为佐药。这三种情况治疗目暴盲，都属于气分病变，所以用人参、白术。即使是血虚者，也必须用人参，这样才能发挥“阳生阴长”的功效。《内经》说：“气脱的人眼睛看不清”，指的就是这种证候。因此，忌讳使用金石类重镇沉降的药物，因为患者的神气浮散于上部，误用此类药物必死无疑。
青盲有两种情况，必须询问其致病根源。如果是因七情所伤，则损伤了神气，可用独参汤，或保元汤加入远志、砂仁、麝香、麦冬、当归身。如果是因精血亏损，则损伤了胆，可用六味地黄丸加入酸枣仁、柴胡。这些都不容易治愈，而失神者尤其难以见效。如果能保全真气，屡次有不治疗而自愈的案例。如果是年事已高及大病之后，或者心肾不充盈的人，虽然治疗也难以痊愈。世人只见眼睛失明，就称之为青盲，这是非常错误的。所谓青盲，是指瞳神大小正常，没有缺损损坏，仔细观看，与好眼一般无异，只是患者自己看不见东西，这才是青盲这一证候。如果瞳神有任何异常的气色，那就是内障，不是青盲。
Bao Mang (Sudden Blindness) refers to the sudden loss of vision. There are three causes for this disease: Yang deficiency (Yang Gua), Yin isolation (Yin Gu), and Spirit dispersion (Shen Li). This condition belongs to the category of obstruction and rebellion of Qi mechanism.
When caused by damage to Yang, it often stems from sudden anger and rebellion, indulgence in alcohol, preference for spicy foods, or occurs in individuals with prolonged illness, febrile diseases, or phlegm-fire. Symptoms include irritability, constipation, and thirst.
When caused by damage to Yin, it is often due to excessive sexual desire or grief and weeping. The onset resembles that of stroke (Zhong Feng) or cold invasion (Zhong Han).
When caused by damage to the Spirit, it results from excessive thinking, boundless mental exertion, extreme sorrow, or fright and panic. Patients may appear dazed, and during an attack, they exhibit a state akin to idiocy.
It is frequently observed that individuals with Yin deficiency and scant body fluids lose their sight upon waking after an episode of vertigo caused by head wind or phlegm-fire. Those who can maintain proper care may recover spontaneously without treatment.
For those with severe Qi deficiency, a large dose of Renshen Gao (Ginseng Paste) should be administered urgently. For blood deficiency, a large decoction of Huangqi (Astragali Radix) and Danggui (Angelicae Sinensis Radix) should be prepared to mix with Renshen Gao.
For cases involving dampness, Baizhu (Atractylodis Macrocephalae Rhizoma) serves as the sovereign herb, accompanied by Huangqi (Astragali Radix), Fuling (Poria), and Chenpi (Citri Reticulatae Pericarpium) as ministering herbs, and Fuzi (Aconiti Lateralis Radix Praeparata) as an assistant herb. In treating sudden blindness of the eyes through these three methods, the pathology lies primarily in Qi; hence, Renshen (Ginseng Radix et Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) are used. Even in blood deficiency, Renshen (Ginseng Radix et Rhizoma) is necessary to achieve the effect of "Yang generating Yin growth." The Classic states, "When Qi escapes, vision becomes unclear," which describes this syndrome. Therefore, minerals and metals with heavy, sinking properties are contraindicated because the Spirit and Qi are floating upward; using such drugs will inevitably lead to death.
Qing Mang (Green Blindness) has two types, and one must inquire about the source of the disease. If injured by the Seven Emotions, the Spirit is damaged; treat with Dushen Tang (Single Ginseng Decoction) or Baoyuan Tang (Preserve the Origin Decoction) added with Yuanzhi (Polygalae Radix), Sharen (Amomi Fructus Rotundus), Shexiang (Moschus), Maidong (Ophiopogonis Radix), and Danggui Shen (Angelicae Sinensis Radix). If injured by essence and blood, the Gallbladder is impaired; treat with Liuwei Wan (Six-Ingredient Rehmannia Pill) added with Suanzaoren (Ziziphi Spinosae Semen) and Chaihu (Bupleuri Radix). These conditions are difficult to cure, and those who have lost their Spirit are particularly hard to treat effectively. However, those who can preserve their True Qi often recover spontaneously. For the elderly or those recovering from serious illness, or those with insufficient Heart and Kidney, treatment is unlikely to succeed. It is a great error for people to simply call any blindness "Qing Mang" upon seeing it. Qing Mang is characterized by a pupil of normal size without defect or damage; closely examined, it looks identical to a healthy eye, yet the patient cannot see. Only then is it considered this syndrome. If the pupil exhibits any abnormal coloration, it is an internal cataract (Nei Zhang), not Qing Mang.
