《阴阳应象大论》曰∶天有四时，以生长收藏，以生寒暑燥湿风。寒暑燥湿风之发耶，
发而皆宜时，则万物俱生；寒暑燥湿风之发耶，发而皆不宜时，则万物俱死。故曰∶生于四
时，死于四时。又曰∶人有五脏，化为五气，以生喜怒忧悲恐。喜怒忧悲恐之发耶，发而皆
中节，则九窍俱生；喜怒忧悲恐之发耶，发而皆不中节，则九窍俱死。故曰∶生于五藏，死
于五脏。目，窍之一也。光明视见，纳山川之大，及毫芒之细，悉云霄之高，尽泉沙之深，
至于鉴无穷为有穷，而有穷又不能为穷，反而聚之。则乍张乍敛，乍动乍静，为一泓一点之
微者，岂力为强致而能此乎！是皆生生自然之道也。或因七情内伤，五贼外攘，饥饱不节，
劳役异常。足阳明胃之脉，足太阴脾之脉，为戊己二土，生生之原也。七情五贼，总伤二脉
，饥饱伤胃，劳役伤脾，戊己既病，则生生自然之体，不能为生生自然之用，故致其病，曰
七情五贼劳役饥饱之病。其病红赤睛珠痛，痛如针刺，应太阳，眼睫无力，常欲垂闭，不敢
久视，久视则酸疼，生翳，皆成陷下。所陷者，或圆或方，或长或短，或如点，或如缕，或
如锥，或如凿，证有印此者，柴胡复生汤主之，黄连羊肝丸主之。痛睛甚者，当归养荣汤主
之，助阳活血汤主之，加减地黄丸主之，决明益阴丸主之，加当归、黄连羊肝丸主之，龙脑
黄连膏主之。以上数方，皆群队升发阳气之药。其中有用黄连、黄芩之类者，去五贼也。
鼻碧云散，亦可见用。最忌大黄、芒硝、牵牛、石膏、栀子之剂，犯所忌，则病愈厉。
《黄帝内经·素问·阴阳应象大论》中说：天有春、夏、秋、冬四季，用来生长、繁荣、收敛、收藏，从而产生寒、暑、燥、湿、风五种气候。寒、暑、燥、湿、风这些气候的出现，如果都符合时节规律，那么万物就能生长；如果不符合时节规律，那么万物就会死亡。所以说：万物生于四时，也死于四时。又说：人有五脏，化生为五气，从而产生喜、怒、忧、悲、恐五种情志。喜、怒、忧、悲、恐这些情志的发泄，如果都能合乎节度，那么九窍（眼、耳、鼻、口等）功能正常；如果情志发泄不合节度，那么九窍功能就会衰竭。所以说：生命源于五脏，病变也源于五脏。眼睛，是九窍之一。它能光明视物，容纳山川的宏大景象，以及毫芒般的细微之物，看清云霄的高远，探尽泉沙的深邃，甚至能将无穷的境界转化为有限的感知，而有限的感知又无法穷尽无穷，反而将目光汇聚。于是眼睛时而张开时而闭合，时而运动时而静止，成为那一泓清水般微小的一点，这难道是凭借强力所能达到的吗！这都是生生不息的自然之道啊。
有时候因为七情（喜、怒、忧、思、悲、恐、惊）内伤，五贼（风、寒、暑、湿、燥、火中的邪气，此处指代外感邪气或内在致病因素）外扰，饥饱没有节制，劳役过度异常。足阳明胃经和足太阴脾经，分别对应戊土和己土，是生命生成的本源。七情和五贼总归损伤这两条经脉，饥饿与过饱损伤胃，劳累与役使损伤脾。戊土和己土既已患病，那么生生不息的自然本体，就不能发挥其生生不息的作用，因此导致疾病，称为“七情五贼劳役饥饱之病”。这种病症表现为眼球红赤疼痛，疼痛如针刺，症状关联太阳经，眼睑无力，常常想要垂下闭合，不敢长时间注视，久视则感到酸疼，生成翳障，且翳障多呈凹陷状。所形成的凹陷，有的圆形，有的方形，有的长，有的短，有的像点，有的像线，有的像锥尖，有的像凿孔。证候表现与此相同的，用柴胡复生汤主治，黄连羊肝丸主治。眼睛疼痛剧烈的，用当归养荣汤主治，助阳活血汤主治，加减地黄丸主治，决明益阴丸主治，或在黄连羊肝丸中加入当归主治，龙脑黄连膏主治。以上几个方剂，都是聚集升发阳气的药物。其中有用到黄连、黄芩这类药物的，是为了去除五贼邪气。另外，鼻碧云散也可以使用。最忌讳使用大黄、芒硝、牵牛子、石膏、栀子这类药剂，如果触犯禁忌，病情就会更加严重。
The *Suwen: Yin-Yang Yingxiang Dalun* (Great Treatise on the Correspondence of Yin and Yang in the Basic Questions) states: Heaven has the four seasons, which govern growth, flourishing, harvesting, and storing, thereby generating cold, heat, dryness, dampness, and wind. When these climatic factors—cold, heat, dryness, dampness, and wind—arise, if they occur in due season, all things grow; if they arise out of season, all things perish. Thus it is said: "Born of the four seasons, dying by the four seasons." It also says: "Humans have five zang organs, which transform into five qi, giving rise to joy, anger, worry, grief, and fear. When these emotions—joy, anger, worry, grief, and fear—are expressed, if they are moderate and within proper limits, the nine orifices function normally; if they are excessive and immoderate, the nine orifices fail. Thus it is said: 'Life originates from the five zang organs, death arises from the five zang organs.'" The eyes are one of the orifices. They possess brightness and vision, encompassing the vastness of mountains and rivers, as well as the minutiae of hairs and grains, perceiving the height of clouds and the depth of springs and sands, transforming the infinite into the finite, while the finite cannot exhaust the infinite, instead converging the gaze. Thus, the eyes open and close, move and rest, becoming a tiny point like a pool of clear water. Is this achieved through forceful effort? No, this is the natural way of continuous generation.
However, sometimes internal injury caused by the seven emotions (joy, anger, worry, thought, grief, fear, fright), external disturbance by the five thieves (pathogenic factors), irregular eating and drinking, and abnormal physical exertion occur. The Foot-Yangming Stomach Meridian and the Foot-Taiyin Spleen Meridian correspond to Wu Earth and Ji Earth, respectively, serving as the source of life's generation. The seven emotions and five thieves collectively injure these two meridians; irregular meals injure the stomach, while overexertion injures the spleen. Once Wu and Ji Earth are diseased, the natural body capable of continuous generation cannot perform its function of continuous generation, thus leading to illness, termed "Disease of Seven Emotions, Five Thieves, Exertion, and Irregular Meals." The symptoms include redness and pain in the eyeball, pain like needle pricks, involvement of the Taiyang channel, weakness of the eyelids with a constant desire to close them, inability to gaze for long periods, soreness upon prolonged gazing, formation of nebulae (corneal opacities), which often present as depressions. These depressions may be round, square, long, short, dot-like, thread-like, cone-shaped, or chisel-shaped. For cases presenting with these signs, Chaihu Fusheng Tang (Bupleurum Revitalizing Decoction) or Huanglian Yanggan Wan (Coptis Lamb Liver Pill) should be administered. For severe eye pain, Danggui Yangrong Tang (Angelica Nourishing Harmony Decoction), Zhuyang Huoxue Tang (Yang-Boosting Blood-Activating Decoction), Jiadi Dihuang Wan (Modified Rehmannia Pill), Jueming Yiyin Wan (Vision-Improving Yin-Nourishing Pill), or Huanglian Yanggan Wan modified with Danggui (Angelica) should be used. Longnao Huanglian Gao (Borneol Coptis Ointment) may also be applied. All the aforementioned formulas consist primarily of herbs that ascend and generate yang qi. Among them, herbs such as Huanglian (Coptidis Rhizoma) and Huangqin (Scutellariae Radix) are used to eliminate the pathogenic factors of the five thieves. Bibi Yun San (Nose Blue Cloud Powder) may also be utilized. One must strictly avoid agents containing Dahuang (Rhei Radix et Rhizoma), Mangxiao (Natrii Sulfas), Qianniu (Pharbitidis Semen), Shigao (Gypsum Fibrosum), and Zhizi (Gardeniae Fructus). Violating these contraindications will exacerbate the disease.
