阴阳以和为本，过与不及，病皆生焉。急者，紧缩不解也；弛者，宽纵不收也。紧缩属
阳，宽纵属阴，不解不收，皆为病也。手太阳肺，为辛为金也。主一身皮毛，而目之上下睫
之外者，亦其属也。手少阴心，为丁；手太阳小肠，为丙。丙丁为火，故为表里，故分上下
，而目之上下睫之内者，亦其属也。足厥阴肝，为乙，乙为木，其脉循上睫之内，火其子也
，故与心合。心肝小肠三经受邪，则阳火内盛，故上下睫之内，紧缩而不解也。肺金为火克
，受克者必衰，衰则阴气外行，故目之上下睫之外者，宽纵而不收也。上下睫既内急外弛，
故睫毛皆倒而刺里，睛既受刺，则深赤生翳。此翳者，睛受损也。故目所病者皆具。如羞明
沙涩，畏风怕日，沁烂，或痛或痒，生眵流泪之证俱见。有用药夹施于上睫之外者，欲弛者
急，急者弛。而睫毛无倒刺之患者，非其治也。此徒能解厄于目前，而终复其病也。何则？
为不审过与不及也，为不能除其原病也。治法∶当攀出内睑向外，速以三棱针乱刺出血，以
左手大指甲迎其针锋，后以黄 防风饮子主之，无比蔓荆子汤主之，决明益阴丸主之，菊花
决明散主之， 鼻碧云散亦宜兼用。如是则紧缩自弛，宽纵渐急，或过不及，皆复为和
，药夹之治，忍勿施也，徒为苦耳。智者宜审此。
阴阳以和谐为根本，太过或不及，疾病便由此产生。所谓“急”，是指紧缩而不能舒展；所谓“弛”，是指松弛而不能收敛。紧缩属于阳，松弛属于阴，不能舒展和不能收敛，都是病态。手太阴肺经（注：原文作“手太阳肺”，据中医理论及上下文逻辑，此处应指手太阴肺经，因肺属金、主皮毛，且后文有“肺金”之说，故按正确经络名处理并标注），其性辛，五行属金。肺主一身之皮毛，而眼睑上下睫毛的外侧部分，也归属于肺。手少阴心经，其天干为丁；手太阳小肠经，其天干为丙。丙和丁五行属火，所以心和小肠互为表里，分别位于上焦和下焦，而眼睑上下睫毛的内侧部分，则归属于它们。足厥阴肝经，其天干为乙，乙五行属木，其经脉循行于眼睑内侧，木生火，火是木之子，所以肝与心相合。如果心、肝、小肠这三条经脉受到邪气侵袭，就会导致阳火在内亢盛，所以上下睫毛的内侧会紧缩而不能舒展。肺金被火克制，受克制的脏腑必然衰弱，衰弱则阴气向外运行，所以眼睑上下睫毛的外侧会松弛而不能收敛。既然上下睫毛出现了内侧紧急、外侧松弛的情况，那么睫毛就会全部向内倒刺入眼球内部。眼睛既受到倒刺的损伤，就会出现深层发红、生成翳膜的症状。这种翳膜，就是眼睛受损的表现。因此，眼部各种病症都会具备。如羞明怕光、沙涩感、畏风怕日、溃烂，或者疼痛或瘙痒、分泌眼屎、流泪等症状都会出现。如果在眼睑外侧使用药夹进行治疗，试图让松弛的变得紧急，让紧急的变得松弛，但对于睫毛没有倒刺的患者来说，这并不是正确的治疗方法。这只能暂时解除眼前的痛苦，但最终疾病还是会复发。为什么呢？因为未能审察病因是太过还是不及，也不能去除根本的致病原因。治疗方法：应当将内眼睑翻出向外，迅速用三棱针进行散刺出血，用左手大拇指指甲抵住针尖后方以防过深，之后主要使用黄芩防风饮子治疗，也可以用无比蔓荆子汤治疗，决明益阴丸治疗，菊花决明散治疗，碧云散也可以兼用。像这样，紧缩的自然会松弛，松弛的逐渐会变得紧急，无论是太过还是不及，都能恢复和谐。对于药夹的治疗，要忍耐不要施用，那只会徒增痛苦。明智的人应该审慎考虑这一点。
Harmony between Yin and Yang is the foundation; diseases arise from either excess or deficiency. "Ji" (Urgency/Tightness) refers to contraction without relaxation; "Chi" (Laxity/Relaxation) refers to looseness without retraction. Contraction belongs to Yang, while laxity belongs to Yin. Failure to relax or retract constitutes pathology. The Hand-Taiyin Lung Meridian (Note: Original text says "Hand-Sunyang Lung", corrected to Hand-Taiyin based on TCM theory as Lung belongs to Taiyin), characterized by Pungent flavor and Metal element, governs the skin and hair of the whole body. The outer aspects of the upper and lower eyelashes also belong to it. The Hand-Shaoyin Heart Meridian corresponds to Ding; the Hand-Taiyang Small Intestine Meridian corresponds to Bing. Bing and Ding belong to Fire, thus they are exterior-interior pairs, dividing the upper and lower regions. The inner aspects of the upper and lower eyelashes also belong to them. The Foot-Jueyin Liver Meridian corresponds to Yi, which belongs to Wood. Its meridian courses along the inner aspect of the eyelids. Since Wood generates Fire, and Fire is the child of Wood, the Liver harmonizes with the Heart. When pathogenic factors invade the Heart, Liver, and Small Intestine meridians, Yang-Fire becomes excessive internally. Consequently, the inner aspects of the upper and lower eyelashes contract and fail to relax. Lung-Metal is controlled by Fire; when controlled, the affected organ weakens. Weakness allows Yin-Qi to move outward, causing the outer aspects of the upper and lower eyelashes to become lax and fail to retract. With the inner eyelids tight and the outer eyelids lax, all eyelashes turn inward and prick the interior of the eyeball. Once the eyeball is pricked, deep redness and the formation of nebulae (corneal opacities) occur. This nebula represents damage to the eye. Thus, various ocular diseases manifest. Symptoms such as photophobia, gritty sensation, aversion to wind and sunlight, ulceration, pain or itching, discharge of pus, and tearing may all appear. Applying medicinal clamps to the outer side of the upper eyelid, attempting to make lax parts tight and tight parts loose, is not the correct treatment for patients whose eyelashes do not invert. Such methods only provide temporary relief but ultimately fail to cure the disease. Why? Because one fails to examine whether the cause is excess or deficiency, and fails to eliminate the root cause. Treatment method: Evert the inner eyelid outward and rapidly puncture with a three-edged needle to induce bleeding. Use the thumbnail of the left thumb to guide the needle tip to prevent depth injury. Subsequently, treat primarily with Huangqin Fangfeng Yin (Scutellaria and Saposhnikovia Decoction), Bimi Manjingzi Tang (Peerless Vitex Decoction), Jueming Yiyin Wan (Clear Vision Nourishing Yin Pill), Juhua Jueming San (Chrysanthemum Clear Vision Powder), and Biyun San (Blue Cloud Powder) can be used concurrently. In this way, tightness will naturally relax, and laxity will gradually tighten. Whether due to excess or deficiency, harmony will be restored. One should endure and avoid using medicinal clamps, as they only cause unnecessary suffering. Wise individuals should reflect carefully on this.
