蟹睛疼痛的症状，与黑翳（角膜云翳）的症候相同，病位起于瞳仁，属于肝肾病变。其翳障形态如豆、如珠，状似蟹眼者，称为蟹睛。这种翳障突起占据瞳孔，特点是根部小而顶部宽大，这是膈部（胸膈）的病变。因膈中壅滞毒邪，气机潜伏化热，导致眼部红赤干涩、流泪、疼痛难睁，羞明怕日。该翳障发起时尖高隆起，形状如同蟹眼一般。治疗方法与前症相同，用小锋针刺破排出恶水，待恶水流尽后症状即平复，随后点用淡淡的丹药以消除翳根。服药方面则不同于前症，宜使用泻肝补肾的方剂。空腹时服用补肾药物，饭后服用泻肝散。

旋螺尖起的症状，是热邪积聚于肝，毒邪壅塞于膈门，充盛攻冲眼球导致疼痛。中央瞳仁逐渐变为青白色，忽然凸起血丝缠绕，这是膜侵入水轮（肾所主之黑睛），肝与肾二经并见热象，旋转隆起形成尖端，形状像螺尾，因此称为旋螺尖起证。治疗方法：宜用阴二阳四丹吹入眼中点治，或调拌鳝鱼血点涂在尖端处。若病程日久，需用锋针对准瞳仁中央刺入半分深，放出恶水，以此达到平衡治疗的目的。治疗后用纸封护患处静养，避风忌口，十余日即可痊愈。内服双解散、郁金酒调散的方药。

The symptoms of crab-eye pain are identical to those of black nebula (corneal opacity), originating from the pupil, and constitute a disease of the Liver and Kidney. The opacity resembles a bean or a pearl; when it protrudes over the pupil with a small root and a large apex, it is termed "crab-eye." This condition stems from pathology in the Diaphragm (chest and diaphragm region), where toxic heat stagnates within the Diaphragm, causing Qi to become latent and transform into heat. Symptoms include redness, dryness, tearing, severe pain making eye opening difficult, photophobia, and aversion to sunlight. The opacity rises sharply and high, resembling the shape of a crab's eye. The treatment method is the same as for the preceding syndrome: use a fine-pointed needle to puncture and drain the foul fluid; once drained, the swelling subsides. Subsequently, apply mild Dan Yao (mineral/chemical ointment) to resolve the opacity's root. Medication differs from the previous case; one should administer formulas that purge Liver heat and tonify Kidney deficiency. Take Kidney-tonifying medicine on an empty stomach, and take Xie Gan San (Liver-Purging Powder) after meals.

Spinning-Spiral Apex Rising is characterized by heat accumulating in the Liver and toxicity obstructing the Diaphragm gate, attacking the eyeball and causing pain. The central pupil gradually turns bluish-white, suddenly protruding with entangled blood vessels. This indicates membrane invasion into the Water Wheel (the cornea/pupil area governed by the Kidney). Heat from both the Liver and Kidney rotates and rises to form an apex, resembling a snail's tail; thus, it is named the Spinning-Spiral Apex Rising syndrome. Treatment: Apply Yin Er Yang Si Dan (a specific mineral powder) via insufflation, or apply leech blood mixed with eel blood to the apex. If the condition has persisted for years, use a sharp needle to penetrate half a cun into the center of the pupil to drain foul fluid, thereby restoring balance. Seal the area with paper for rest, avoid wind, and observe dietary restrictions; recovery takes about ten days. Internally, administer Shuang Jie San (Double-Resolution Powder) and Yu Jin Jiu Tiao San (Turmeric Wine-Adjusted Powder).
