灵枢论疾诊尺篇曰目赤色者病在心白在肺青在肝黄在脾黑在肾黄色不可名者病在胸中
白睛黄淡脾伤泄痢黄而浊兼面如熏湿盛黄胆黄如橘子明者热多黄中兼青紫脉芤是瘀血胸

眼黑而颊赤者热痰也眼胞上下如烟煤者痰也眼黑而行走艰难呻吟者入骨痰也其证遍体骨
节酸痛眼黑面带土色四肢痿痹屈伸不便者风痰也
目黄大烦脉大为病进目黄心烦脉和者为病将愈目睛晕黄衄未止平人见黑气起口鼻耳目者
凶目睛黄酒疸黄白及面眼胞上下肿者谷疸其人心下必痞胀
明堂眼下青色多欲精神劳伤不尔即未睡
面黄目青为伤酒
面无精光齿黑者凶
瘰 赤脉贯瞳者凶一脉一岁死一脉半岁半死二脉二岁死三脉三岁死
目间青脉起者掣痛乃少阳胆经之滞也瞳子高硕者太阳不足
病患面目俱等者吉
面黄目青面黄目赤面黄目白面黄目黑皆不死
面赤目白面青目黑面黑目白面赤目青皆死
面目有黄色是有胃气为吉前二节一有胃气一无胃气
伤寒眼下青色属挟阴挟阴者俗指房事也

目睛不了了鼻中呼不出吸不入气短促而冷者阴病目睛了了鼻中呼吸出入能往能来口鼻息
长而皆热者阳病也
《灵枢·论疾诊尺篇》说：眼睛发红，病位在心；眼白发黄，病位在肺；眼周发青，病位在肝；面色发黄，病位在脾；面色发黑，病位在肾。如果黄色无法明确归类，病位在胸中。
白眼球颜色淡黄，是脾脏受损导致的泄泻或痢疾；黄色浑浊且面色像被烟熏一样，是湿邪盛极导致的黄疸；黄色明亮如橘子色，是热邪偏盛；黄色中夹杂青色和紫色，脉象芤（kōu，浮大中空，如按葱管），这是瘀血阻滞在胸中。
双眼发黑且脸颊发红，是热痰证；眼睑上下颜色如烟煤熏黑，是痰证；双眼发黑且行走艰难、呻吟不止，是深入骨骼的痰证，其症状表现为全身骨节酸痛；双眼发黑、面色呈土色、四肢痿软麻痹、屈伸不便，是风痰证。
眼睛发黄且极度烦躁、脉象大，说明病情进展；眼睛发黄但心烦轻微、脉象调和，说明病情即将痊愈。眼睛昏花视物模糊且有鼻出血，说明出血未止。健康人如果出现口、鼻、耳、目周围出现黑色气色，预后凶险。
眼睛发黄是酒疸（jiǔ dǎn，因饮酒过度导致的黄疸）；眼睛发黄、白色巩膜及面部、眼睑上下肿胀，是谷疸（gǔ dǎn，因饮食不节导致的黄疸），这类患者心下（胃脘部）必然痞塞胀满。
明堂（此处指面诊部位或特定文献记载）眼下呈现青色，多为性欲过盛导致的精神劳伤；否则就是尚未入睡的表现。
面色黄而眼睛青，是饮酒损伤所致。
面色无光泽、牙齿发黑，预后凶险。
瘰疬（luǒ lì，颈部淋巴结结核）患者若赤色血脉贯穿瞳孔，预后凶险：一条脉主一年死，半条脉主半年死，两条脉主两年死，三条脉主三年死。
眼角出现青色脉络并伴有牵引性疼痛，这是少阳胆经气机阻滞所致。瞳仁高突上视，是太阳经气不足。
病患面目色泽协调一致者，预后吉祥。
面色黄而眼睛青、面色黄而眼睛红、面色黄而眼睛白、面色黄而眼睛黑，这些情况都不致死。
面色赤而眼睛白、面色青而眼睛黑、面色黑而眼睛白、面色赤而眼睛青，这些情况都会致死。
面目中带有黄色，说明还有胃气，预后吉祥。前两段分别论述了“有胃气”和“无胃气”的情况。
伤寒病患者眼下呈现青色，属于挟阴（xié yīn，兼夹阴寒之邪或房劳内伤）；挟阴是民间对房事过度导致疾病的俗称。
《金匮要略》说：眼睛直视不能转动者，难以治愈。瞪直属于太阳经气绝断，因为太阳经主管筋脉，所以有的版本写作“死”。另外，面色青主痛，面色黑主劳损，面色赤主风邪，面色黄主小便困难，面色鲜明光亮主有水饮停留。“鲜明”即俗语所说的水汪汪的样子，这些都指观察白眼球（巩膜）。
眼睛昏花视物不清，鼻孔气息呼不出吸不进，气短促且寒冷，这是阴病；眼睛清明视物清晰，鼻孔呼吸出入顺畅，口鼻气息长且温热，这是阳病。
The *Ling Shu: Lun Ji Zhen Chi* chapter states: Redness of the eyes indicates disease in the Heart; yellowing of the sclera (white part of the eye) indicates disease in the Lung; blueness around the eyes indicates disease in the Liver; yellow complexion indicates disease in the Spleen; black complexion indicates disease in the Kidney. If the yellow color cannot be clearly categorized, the disease is located in the chest.
Pale yellow sclera indicates spleen injury leading to diarrhea or dysentery; turbid yellow with a complexion resembling smoke indicates severe dampness leading to Huang Dan (Jaundice); bright yellow like an orange indicates excess heat; yellow mixed with blue and purple, with a Kou pulse (floating, large, and empty, felt like pressing on a scallion stem), indicates blood stasis in the chest.
Blackening of both eyes with red cheeks indicates hot phlegm; soot-like darkening of the upper and lower eyelids indicates phlegm; blackening of the eyes accompanied by difficulty walking and groaning indicates bone-deep phlegm, presenting with generalized joint soreness and pain; blackening of the eyes, earthen-colored complexion, flaccid paralysis of the four limbs, and difficulty bending and extending them indicate wind-phlegm.
Yellow eyes with extreme irritability and a large pulse indicate disease progression; yellow eyes with mild heart vexation and a harmonious pulse indicate the disease is about to resolve. Blurred vision with epistaxis indicates bleeding has not stopped. In a healthy person, the appearance of black qi around the mouth, nose, ears, and eyes is ominous.
Yellow eyes indicate Jiu Dan (Alcoholic Jaundice); yellow eyes, white sclera, and swelling of the face and eyelids indicate Gu Dan (Grain Jaundice); such patients must have epigastric stuffiness and distension.
Cyanosis under the eyes in the Ming Tang (face diagnosis area) indicates excessive sexual desire leading to mental exhaustion; otherwise, it indicates sleeplessness.
Yellow complexion with blue eyes indicates alcohol injury.
Lack of luster in the face and black teeth are ominous signs.
In Luo Li (Scrofula), if red vessels penetrate the pupil, it is ominous: one vessel indicates death in one year, half a vessel in half a year, two vessels in two years, and three vessels in three years.
Blue vessels rising at the corners of the eyes with pulling pain indicate stagnation of the Shaoyang Gallbladder meridian. High and fixed pupils indicate insufficiency of the Taiyang meridian.
If the patient's face and eyes show coordinated colors, the prognosis is auspicious.
Yellow complexion with blue eyes, yellow complexion with red eyes, yellow complexion with white eyes, and yellow complexion with black eyes are all non-fatal.
Red face with white eyes, green face with black eyes, black face with white eyes, and red face with green eyes are all fatal.
The presence of yellow in the face and eyes indicates the presence of Stomach Qi, which is auspicious. The previous two sections discuss "having Stomach Qi" and "lacking Stomach Qi."
In Shang Han (Cold Damage) patients, cyanosis under the eyes belongs to Xie Yin (concomitant Yin-cold or internal injury from sexual activity); Xie Yin is the common term for diseases caused by excessive sexual intercourse.
The *Jin Gui Yao Lue* states: Eyes that are straight open and unable to move are incurable. Straight fixation belongs to the extinction of the Taiyang meridian, as the Taiyang governs the sinews, hence some versions write "death." Furthermore, green complexion indicates pain, black indicates labor/exhaustion, red indicates wind, yellow indicates difficulty in urination, and bright/lustrous complexion indicates retained fluid. "Bright" refers to the colloquial description of watery eyes, all referring to the observation of the sclera.
Blurred vision with inability to inhale or exhale through the nose, shortness of breath, and coldness indicate Yin disease; clear vision with smooth inhalation and exhalation through the nose, long breaths, and warmth indicate Yang disease.
