风邪过后，患者的神气大损，风轮（黑睛）受损严重。风轮受损，原本如吹弹可破般脆弱。瞳仁虽尚圆活、凝脂未败，虽有瘢痕但目光未坠散。目光未坠散，勉强可以维持现状，又何必过分忧愁呢？
此症表现为风轮上有一颗黑珠突出，周围被肤翳略微缠绕。这是因为暴风客热以及水衰火炎之证，医生治疗不当，导致凝脂、黄液、木疡等病症侵蚀并穿破青睛（黑睛），黑睛从破处脱出，起初像苍蝇头，中间像蟹眼，严重时横长如黑豆，因此称为上述名称。若患处柔软且不疼痛，金井（瞳孔）只是偏斜而未败坏，确实可以许诺其能够平复。间或有结痂如豆壳状，壳脱落后才痊愈的，然而即使有妙手回春之术，瘢痕终究难以避免。如果患处尖硬且疼痛紧迫，药物再误治，则黑白混为一色，蟹睛决不能平复。否则必然破裂，青黄之色重叠出现，眼睛难道要随之失明吗？
蟹睛本是由医药妄乱逼迫而成，一切汗、吐、下等攻伐之法皆不适用。应当选用温和而兼有补益作用的方剂，加入五味子、枣仁、白芍，徐徐酸收敛摄，日久自然收入。若未经诊治，此时木火强盛，脉象必浮弦而数，须用抑青丸、泻青丸、八正散、逐客汤等方剂洁净脏腑，然后才适宜调和。宜滋养并细心调理，绝大多数不会有害。
离离可见的赤脉如虬龙丝线，从银海（内眦/泪窍）发出，进入水池（外眦/血络），纵横交错，粗细长短不一，昏沉感如云冉冉升起，疼痛紧迫泪水垂落，如同白虹贯穿太阳，类似红线穿过珍珠。深知这是水困金弱无助，导致风狂火更旺盛所致。
此症乃是赤脉虬丝，纵横交错，上行气轮（白睛）而缠绕风轮（黑睛），最不易治疗。这是因为水泄金元，风木燥烈而无制约的缘故。况且火盛木焚，风胜木折，即使是松柏之姿也在所难免，何况是肝胆呢？因此风火合邪，赤脉即生，赤脉生则漫睛翳障，热泪流下而疼痛紧迫，世人称之为白虹贯日之变事，因此征引其征兆、模拟其形状而命名。那些丝脉只在气轮，虽然纵涩紧不爽，且有微泪赤虬者，这是目病的常态，不足为虑。即使风轮有障，医者自能研究，这里无需赘述。《内经》说：赤脉从上往下走的，是太阳病；从下往上走的，是阳明病；从外向内走的，是少阳病；从内向外走的，是少阴病。太阳病宜温散，阳明病宜寒下，少阳病宜和解，少阴病宜清解。懂得这些，则生克制化的道理不难体会，用来治病，如击鼓应槌般准确。遇到赤丝虬脉，这是风火眼病所必有的，大小粗细，位置不固定，如何区分上下辨别内外！只看脉大贯穿过睛珠，便使用导赤散加黄连服用，若不效或增加翳障，经久在目的，这是风热不制，恐怕成为痼疾，须用既济丸、人参固本丸、百合固金汤，圆融通变来主治，应当必定有效。
After the wind pathogen passes, the patient's spirit is greatly damaged, and the Fenglun (cornea) suffers severe injury. The Fenglun is compromised, becoming as fragile as if it could be broken by a blow or a touch. Although the pupil remains round and active, with the coagulated fat (lipoid material) intact, and although scars exist, the visual light has not fallen (vision is preserved). Since the visual light has not fallen, one can merely make do; why worry excessively?
This condition presents with a black nodule protruding on the Fenglun (cornea), slightly wrapped around by peripheral skin-like nebula (fibrous tissue). This arises from conditions such as "violent wind guest heat" and "water deficiency with fire flaring up." Due to improper medical treatment, diseases such as coagulated fat (lipid keratitis), yellow fluid (hypopyon), and wood ulcer (corneal ulcer) erode and perforate the Qingjing (cornea/sclera complex). The black cornea protrudes from the rupture site, initially resembling a fly's head, then like a crab's eye, and in severe cases, elongating horizontally like a black bean. Hence the aforementioned names. If the lesion is soft and painless, and the Jinjing (pupil) is only deviated but not ruined, recovery can indeed be promised. Occasionally, scabs form like bean shells, healing only after the shell falls off. However, even with masterful skill, scars are ultimately unavoidable. If the lesion becomes sharp, hard, and tightly painful, and medication further errs, black and white will mix indistinguishably, and the crab-eye deformity cannot be resolved. Otherwise, it will inevitably rupture, with green-yellow colors overlapping. Will the eye not become blind?
Crab-eye deformity is originally caused by reckless and chaotic medical interventions forcing the condition. All methods of sweating, vomiting, and purging are unnecessary. One should select formulas that are harmonious and tonifying, adding Schisandra chinensis (Wuweizi), Ziziphus jujuba seed (Zaoren), and White Peony Root (Baishao) to slowly astringe and consolidate. Over time, it will naturally retract. If untreated, Wood and Fire are currently strong, and the pulse must be floating, wiry, and rapid. One must use formulas such as Yiqing Wan (Suppress Green Pill), Xieqing Wan (Drain Green Pill), Bazheng San (Eight-Normal Powder), and Zhuke Tang (Expel Guest Decoction) to cleanse the zang-fu organs, before proceeding to harmonization. Nourishment and careful regulation are indicated; nineteen out of twenty cases will suffer no harm.
Distinct red vessels resembling dragon-like threads emerge from Yin Hai (inner canthus/tear duct area) and enter Shui Chi (outer canthus/blood vessel network), crisscrossing in varying thicknesses, lengths, densities, and sparseness. There is a heavy, cloudy sensation rising slowly, tight pain, and dripping tears, resembling a white rainbow piercing the sun, similar to a red thread threading pearls. It is understood that Water is trapped and Metal lacks support, causing Wind to rage and Fire to intensify.
This condition involves red vessels and dragon-like threads crisscrossing, ascending the Qi Lun (sclera/conjunctiva) and wrapping around the Fenglun (cornea). It is most difficult to treat. This is because Water drains Metal's origin, leaving Wind-Wood dry and uncontrolled. Moreover, when Fire is excessive, Wood burns; when Wind prevails, Wood breaks. Even the resilience of pine and cypress cannot escape this fate, let alone the Liver and Gallbladder. Therefore, Wind and Fire combine, generating red vessels. Once red vessels appear, they cause diffuse corneal opacity and nebula, hot tears flow, and pain is tight. The world calls this phenomenon "White Rainbow Piercing the Sun," naming it based on its signs and shape. Vessels confined only to the Qi Lun, even if rough, tight, and accompanied by slight tearing and red dragon-like threads, are common ocular conditions and need not be worried about. Even if there is an obstruction on the Fenglun, physicians can study it themselves; no need to elaborate here. *Neijing* states: Red vessels moving from top to bottom indicate Taiyang disease; from bottom to top, Yangming disease; from outside to inside, Shaoyang disease; from inside to outside, Shaoyin disease. Taiyang disease should be treated with warming and dispersing; Yangming disease with purging and cooling; Shaoyang disease with harmonizing; Shaoyin disease with clearing. Understanding this makes the principles of generation and restriction easy to grasp, allowing treatment to be as accurate as a drum responding to a mallet. When encountering red filaments and dragon-like veins, which are inevitable in Wind-Fire eye diseases, their size, thickness, and position vary unpredictably, making it impossible to strictly divide them into upper/lower or inner/outer categories! Simply observe if the large vessel penetrates through the eyeball. In such cases, administer Daochi San (Guide Out the Red Powder) with added Coptis chinensis (Huanglian). If ineffective or if opacity increases, and it persists for a long time, this indicates unconstrained Wind-Heat, likely becoming a chronic stubborn disease. One must use Jiji Wan (Ji Ji Pill), Renshen Guben Wan (Ginseng Root-Solidifying Pill), and Baihe Gujin Tang (Lily Bulb Kidney-Solidifying Decoction), applying flexible and adaptive strategies, which should certainly be effective.
