瞳神欹侧。是指瞳孔发生歪斜。有的形状像杏仁或桃核，有的呈三角形或半月形。这是由于肝肾阴液被火热灼烧，导致肾水枯竭、虚火上炎，从而耗损了瞳神。治疗宜用六味丸（由熟地黄、山茱萸、山药、泽泻、牡丹皮、茯苓组成的方剂）加入蒺藜、当归以及清火药物。如果黑睛（角膜）破损，神膏（玻璃体等眼内组织）流出渗漏而导致瞳孔歪斜的，说明瞳神即将完全丧失功能。此时急需补肾治疗。如果黑睛外有蟹睛（虹膜脱出嵌顿于角膜穿孔处）出现，即使蟹睛平复，瞳孔也无法恢复圆形；若伴有脂翳（角膜瘢痕），则终身无法消退。
《内经》说：肝气虚弱则眼睛视物模糊不清，什么也看不见。又说：足少阴肾经发生病变时，会出现坐着想站起来、眼睛视物模糊不清的症状。又说：少阴经所说的“起身后视物模糊不清”，是因为阴精内夺，所以眼睛视物模糊不清。这是眼病且因房事过度所致。大致在房事后症状尤为严重。可用夜光椒红丸治疗。倪仲贤说：《内经》指出，足厥阴肝经主司眼睛，在情志上对应怒。大怒会伤肝，进而损伤脾胃，导致气机不能聚拢；伤肝则导致神水（房水等眼内液体）散失。神水也是依靠气机聚拢而成的。其症状表现为无眼屎眼泪，眼睛疼痛、发痒、畏光、紧缩涩痛。起初只是感觉眼前昏花，如同在云雾中行走；逐渐觉得空中有黑花飞舞；再后来看物体变成两个影像；时间久了光线无法收敛，最终成为废疾。这是因为神水逐渐散失，散了又散，最终完全散尽的缘故。此病不要当作痰证来治，只应当滋养肝肾的阴血。然而必须经过长时间的调养，避免饮食饥饱不均和劳役过度，控制七情（喜、怒、忧、思、悲、恐、惊）和五贼（风、寒、暑、湿、燥、火六种致病因素中的过亢者），才有望见效。如果是久病光线无法收敛的，则不可治愈。有一种情况是因为突然暴怒，导致神水随即散失，光线不再收敛，永远无法治愈。另一种情况是被外力击打，导致神水散失，如同暴怒的情况，也不再能治愈。俗称为青盲（视力严重减退甚至失明）。患者开始时不在意，等到病情形成，医生也不认识，直接说是热邪所致，竟然用凉药收敛治疗。殊不知凉性药对应秋季和金，又会损伤肝木，往往导致残疾后才停止。
睛黄视眇证。黑睛（角膜）黄亮如金色，而视力也轻微模糊，这是因为湿热重浊，浊气熏蒸，清阳之气升入黑睛中，导致黑睛颜色改变。喜好饮酒、嗜食肥甘厚味、体内湿热燥腻的人，常常患此病。治疗其湿痰即可痊愈。可用五苓散（由猪苓、泽泻、白术、茯苓、桂枝组成的方剂）加入茵陈、龙胆草。严重时可用栀子柏皮汤之类的方剂。
Qinshi Qice (Slanting Pupil). This refers to the slanting of the pupil. Its shape may resemble an almond or a peach pit, appearing triangular or crescent-shaped. This is caused by the scorching of the Liver and Kidney Yin fluids, where Kidney Water is exhausted and Deficient Fire flares up, thereby consuming and damaging the Qinshi (pupil). Treatment should employ Liuwei Wan (Six-Ingredient Rehmannia Pill) supplemented with Jili (Tribulus Terrestris), Danggui (Angelica Sinensis), and herbs that clear fire. If the black cornea (Jinghuang) is damaged, and the Shengao (vitreous humor/ocular contents) leaks out causing the pupil to slant, the Qinshi is on the verge of total loss. Urgent treatment to tonify the Kidney is required. If there is Xiejing (iris prolapse through a corneal perforation) outside the cornea, even if the Xiejing flattens, the pupil cannot return to a round shape; if accompanied by Zhiyi (corneal opacity/scarring), it will never detach for life.
The Classics state: "When the Liver is deficient, the eyes become blurred and unable to see." It also states: "When the Foot-Shaoyin Kidney Meridian is disturbed, disease manifests as a desire to rise from sitting, and the eyes are blurred and unable to see." It further states: "What the Shaoyin meridian describes as 'blurred vision upon rising' is due to the internal depletion of Yin essence, hence the eyes are blurred and unable to see." This eye disease is caused by eye pathology combined with sexual indiscretion (Fanglao). Generally, symptoms are particularly severe after sexual activity. Yeguang Jiaohong Wan can be used. Ni Zhongxian stated: The Classics say, "The Foot-Jueyin Liver meridian governs the eyes, and its emotion is Anger. Severe anger injures the Liver, which then injures the Spleen and Stomach, causing Qi to fail to gather; injuring the Liver causes Shenshui (aqueous humor) to scatter. Shenshui is also formed by the gathering of Qi." The symptoms include no discharge or tears, pain, itching, photophobia, and a tight, astringent sensation in the eyes. Initially, vision is merely blurred as if walking in clouds or mist; gradually, one perceives black spots floating in the air; later, objects appear double; over time, light fails to converge, resulting in permanent disability. This is because Shenshui gradually scatters, scattering again and again, until it is completely exhausted. This condition should not be treated as Phlegm; rather, one must nourish the Yin and Blood of the Liver and Kidneys. However, this requires accumulation over years, avoiding irregular eating, excessive labor, and uncontrolled Seven Emotions (Joy, Anger, Worry, Thought, Sadness, Fear, Fright) and Five Thieves (pathogenic factors), so that efficacy may be achieved. If light fails to converge after a long illness, it is incurable. One syndrome occurs due to sudden violent anger, causing Shenshui to scatter immediately and light to cease converging; this is incurable forever. Another syndrome results from being struck by an object, causing Shenshui to scatter, similar to the violent anger case, and is also incurable. This is commonly known as Qingmang (blindness/severe visual impairment). Patients initially disregard it; once established, physicians often fail to recognize it, attributing it directly to Heat and using cooling/astringent medicines. They do not realize that cooling properties correspond to Autumn and Metal, which further injure Liver Wood, often leading to disability before stopping.
Jinghuang Shimiao Syndrome (Yellow Eye with Blurred Vision). The black cornea appears yellow and bright like gold, and vision is slightly blurred. This is due to heavy Damp-Heat and turbid Qi steaming upward, while Clear Yang Qi ascends into the cornea, changing its color. Individuals who enjoy alcohol, crave rich/greasy foods, and have constitutions prone to Damp-Heat, dryness, and stickiness often suffer from this disease. Treating the Damp-Phlegm leads to recovery. Wuling San (Five-Ingredient Poria Decoction) added with Yinchen (Artemisia Capillaris) and Danshen (Gentiana Scabra) is indicated. In severe cases, formulas such as Zhizi Bopi Tang (Gardenia and Phellodendron Bark Decoction) may be used.
