倏尔青睛痛，浑如刺着肤，下虚上则实，里急外多疏。寒热时来去，风痰乍有无，认真阴分病，主治不模糊。
此症病势已衰，黑睛骤然痛如针乱刺也。夫黑属水，病属火，明系水不足而火有余。第脏腑即平，奈何复见
厥象？盖其人不善调养，或更劳力役精，致水下火上，水火未济，邪气搏击，若疮毒鼓脓之意，其证候必来变者。
书曰∶病加于小愈，祸生于怠惰。是之谓也。医宜探本穷因，量进养心汤、全真散、人参补胃汤，务使痛疏或止，
庶免坐而失事。有目未病，忽在此在彼，如针如炙，乃夏令失序，流火为殃。须记其始自何轮，今止某廓，可知
将犯其经。体虚视劳，兼染淋浊之病，荣气不能上潮于睛，多有患者。又目先得前证，继而赤泪头疼，寒热交作，
或旋去旋来，如风寒症状，多属荣卫虚损，腠理不密，外邪邀动风痰。治法，一体橘皮竹茹汤、金匮肾气汤清其
金而降其火，逍遥散、五苓散疏其风而利其水，则得之矣。
由来痒病果何为，为火为风为血亏。有病如痒痒愈甚，
痒而无病病迟迟，点服尽情无治法，请投绝境觅仙医。
此目痒非常比，乃如毒虫行走身上，令人战栗，几不敢者。其故非一∶有风邪之痒。有火邪之痒。有邪退火
拨搔息，气血得行，脉络通畅而痒。有抱病之目，久不治而痒，痒一番则病重一番。总之治后而痒，病必去速。
无故而痒，病来定险。若痒难禁，时时频作，目觉低陷，及痒极揩擦而目脱出者，龄不延矣。泪多者，血虚生火，
须验目内有无形证，以决其病之进退。如无形可验，只痒难忍耐，暂点飞熊丹。不退，霹雳火。再不住，须端详
切脉用药。如弦浮泣出，此风邪，治以香苏散、芎苏饮。脉数而微芤，茶调疏肝散。因嗜酒而致者，葛花解酲汤。
若沉迟濡小，须大补大热，否则必犯乎谚云∶白日着鬼祟，平路跌村人。此之谓也。临症须矜慎毋忽。
忽然感到青睛（黑睛）疼痛，感觉就像针刺入皮肤一样。这是由于下焦虚损而上焦邪气壅实，内部拘急而外部腠理疏松。寒热症状时而出现时而消失，风邪与痰浊有时存在有时没有。必须认真辨别这是阴分病变，治疗主旨不能模糊不清。
这种病症的病势已经衰退，黑睛突然像被乱针刺痛一样。黑色属水，病象属火，这明显是肾水不足而心火有余。虽然脏腑功能看似平静，为什么又会出现厥逆之象？大概是因为患者不善于调养，或者过度劳累耗伤精气，导致肾水下陷、心火上炎，造成水火未能既济，邪气相互搏击，就像疮毒鼓脓的意思一样，其证候必然会发生变局。医书说：“病情在看似好转时加重，灾祸产生于懈怠懒惰。”说的就是这种情况。医生应当探究根本原因，酌情选用养心汤、全真散、人参补胃汤等方剂，务必使疼痛疏解或停止，以免坐视病情恶化而错失良机。
有的人眼睛原本没有生病，忽然在此处或彼处感到像针扎或火烧一样的疼痛，这是因为夏季气候失序，流火为患造成的。必须记住病邪起始于哪一经轮，现在停留在哪一廓，就可以知道将要侵犯哪条经脉。体质虚弱且用眼过度，又兼染淋浊之病的人，由于营气不能上潮滋润眼睛，多有此类患者发作。又有眼睛先出现上述前证，继而出现红眼流泪、头痛，寒热交替发作，或者症状去而复来，如同风寒症状，多属于营卫虚损，腠理不紧密，外邪引动风痰所致。治疗方法，可以用橘皮竹茹汤、金匮肾气汤清肃肺气并降心火，用逍遥散、五苓散疏散风邪并利水湿，这样就能治愈了。
由来已久的瘙痒病究竟是什么原因？是由于火邪、风邪还是血虚亏损？有的病表现为痒，但痒感减轻后病就好了；有的痒感严重却无明显病症，疾病却迁延难愈。如果点药服用后尽情宣泄仍无治法，那就只能求助于绝境中的仙医了。
这种目痒不同于寻常情况，感觉就像有毒的虫子在身上爬行，令人战栗，几乎不敢触碰。其原因不止一种：有因风邪引起的瘙痒；有因火邪引起的瘙痒；有因病邪退去、火热拨动，气血得以运行，脉络通畅而产生的瘙痒；有病眼久治不愈而发痒，每痒一次病情就加重一次。总之，治疗后出现的瘙痒，说明病邪必将迅速去除。无故出现的瘙痒，说明病势一定危险。如果瘙痒难以忍受，时时频繁发作，眼睛感觉低陷，以及痒极时揉搓导致眼球脱出的，寿命就不长了。泪多者，是血虚生火所致，必须检查眼睛内部是否有形之证，以判断疾病的进退。如果没有形之证可查，只是痒得难以忍耐，暂时点用飞熊丹。若不退止，改用霹雳火。再不住手，必须详细诊察脉象并用药。如脉弦浮且伴有哭泣流泪，此为风邪，治疗用香苏散、芎苏饮。脉数而微芤，用茶调疏肝散。因嗜酒而致者，用葛花解酲汤。若脉沉迟濡小，必须大补大热，否则必定会犯谚语所说的：“白日里遭鬼祟，平路上跌跤”，说的就是这个道理。临症时必须谨慎，不可疏忽。
Suddenly, the Qingjing (black cornea) suffers pain, feeling as if needles are piercing the skin. This arises from deficiency in the lower jiao and excess in the upper jiao, with internal tension and external looseness of the couli (skin pores). Alternating chills and fever come and go; wind-pathogen and phlegm appear intermittently. One must carefully identify this as a disease of the Yin aspect, ensuring the treatment principle is clear and unambiguous.
The pathogenic trend of this syndrome has declined, yet the black cornea suddenly feels like it is being pricked by chaotic needles. Black corresponds to Water; the pathology corresponds to Fire. This clearly indicates insufficient Kidney Water and excessive Heart Fire. Although the Zang-Fu organs seem balanced, why does Jue (reversal cold/heat) manifestation reappear? It is likely that the patient fails to maintain proper regimen or engages in laborious work that exhausts essence, causing Water to sink and Fire to rise, resulting in the failure of Water and Fire to interact harmoniously. Pathogenic factors clash, similar to the process of pus forming in a sore, meaning the clinical manifestations will inevitably change. The medical texts state: "Disease worsens when seemingly recovered; disaster stems from negligence." This is precisely what is meant. Physicians should investigate the root cause and appropriately administer Yangxin Tang (Nourish Heart Decoction), Quanzhen San (Complete True Powder), or Renshen Bugeng Tang (Ginseng Stomach-Nourishing Decoction), striving to relieve or stop the pain, thereby avoiding the consequence of inaction leading to missed opportunities for cure.
In cases where the eyes were previously healthy but suddenly experience needle-like or burning pain in various locations, it is due to disordered summer climate causing "flowing fire" to bring disaster. One must note which meridian wheel the pathogen originated from and which sector it currently occupies, to predict which meridian it will next invade. Individuals with weak constitutions, visual fatigue, and concurrent Linzhuo (dysuria/cloudy urine) diseases often suffer from this, as Ying Qi (nutritive energy) fails to ascend to moisten the eyes. Furthermore, if eye symptoms precede with redness, tearing, headache, alternating chills and fever, or recurring patterns resembling wind-cold, these mostly belong to deficiency and damage of Ying and Wei (defensive) Qi, with loose couli allowing external pathogens to trigger wind-phlegm. The treatment method involves using Jupi Zhuru Tang (Tangerine Peel and Bamboo Shave Decoction) and Guizhi Shenqi Tang (Cinnamon Twig and Kidney Qi Decoction) to clear Lung Metal and descend Fire; Xiaoyao San (Free and Easy Wanderer Powder) and Wuling San (Five-Ingredient Powder with Poria) to disperse wind and promote diuresis, thus achieving recovery.
Why do chronic itching conditions arise? They stem from Fire, Wind, or Blood deficiency. In some cases, the symptom is itching, but as itching subsides, the disease resolves; in others, severe itching persists without obvious disease signs, yet the illness lingers. If topical application and oral medication fail to provide relief after thorough administration, one may need to seek miraculous cures in desperate situations.
This type of eye itching is extraordinary, feeling like venomous insects crawling on the body, causing trembling and aversion. The causes are manifold: there is itching caused by Wind-pathogen; itching caused by Fire-pathogen; itching occurring as pathogens retreat and heat dissipates, allowing Qi and Blood to flow freely through unobstructed collaterals; and itching in neglected eyes that worsens with each episode of itching. In summary, itching following treatment indicates rapid elimination of the pathogen. Unprovoked itching signals dangerous disease progression. If itching is unbearable, frequent, accompanied by a sensation of sunken eyes, or so intense that rubbing causes globe protrusion, life expectancy is shortened. Excessive tearing indicates Blood deficiency generating internal Heat. One must examine whether有形 (tangible/structural) signs exist within the eye to determine disease progression. If no tangible signs are found, but itching is intolerable, temporarily apply Feixiong Dan (Flying Bear Pill). If ineffective, use Pili Huo (Thunderbolt Fire). If still uncontrolled, carefully evaluate the pulse and prescribe herbs. A wiry and floating pulse with weeping indicates Wind-pathogen, treated with Xiangsu San (Fragrant Su Powder) or Xiongsu Yin (Sichuan Lovage and Perilla Drink). A rapid and slightly hollow pulse suggests Chetiao Shugan San (Tea Regulating Liver Soothing Powder). Caused by alcohol indulgence? Use Gegua Jiexing Tang (Arctostaphylos Flower Decoction for Alcohol Intoxication). If the pulse is deep, slow, soggy, and small, major tonification and warming are required; otherwise, one risks the proverbial "being haunted by ghosts in broad daylight" or "tripping on flat ground," which refers to such negligence. Clinical practice demands utmost caution and attention.
