这段文字描述了两种外障眼病的症状、禁忌及治疗方法。
第一种情况：这种眼病在初发时，眼睛有时发痒，有时疼痛。发作和停止没有规律。发作时眼球红赤，有血脉显现，流泪，眼屎增多漫溢，导致黑睛（角膜）上横向或竖向出现类似青色的翳膜，数量多少不定。若拖延日久，会造成严重危害，甚至完全损害视力。此病不可用针挑拨，也不可用钩割法治疗。适宜服用茺蔚子散、除热人参汤，并外用点退翳清凉散，可立即痊愈。
诗曰：
黑睛上横竖分布着青色瑕疵，
如同翳膜沉沉，数量或多或寡。
医者仔细观察如此状貌，
根基深沉侵入黑睛，切勿挑摩。
老来担忧日后增添病患，
清除热邪与风邪的药物最为佳妙。
日常出入起居不妨事，但治疗须谨慎，
专心医疗别无他法。

除热人参汤
组成：人参、茯苓、五味子、桔梗、大黄、黑参、黄芩、车前子（各一两）、知母（另注：原文此处重复列出黄芩，且知母标注为两半，依原文记录：黄芩、知母（各两半）——*注：根据常见古籍校勘，此处可能为排版重复或剂量差异，此处忠实于原文文本提取*）。
*修正说明：原文中“黄芩”出现了两次，一次在一两组，一次在两半组。通常方剂中同一味药不重复列出除非不同炮制或剂量。此处按原文结构处理，但实体提取时仅保留唯一名称。*

制法与用法：将上述药材捣碎研成细末，研磨均匀细腻为佳。每次临睡前，取少许药散（半字量）干撒入眼内。
第二种情况：这种眼病在初发时，有时疼痛，这都是因为毒风上冲入脑，积热停留在肝膈之间，导致眼内生出如玉色般的翳膜，遮盖满瞳仁。此类疾病不宜使用针刺、切割、熨烫或烙法治疗。适宜服用退翳散，可立见疗效。
诗曰：
黑睛上方浮云般呈现玉色，
还因疮疡之后遗留病根。
施用磨翳膏剂和散剂，
拱手向神医寻求无门之妙策。
服药以治风兼去热邪，
还睛丸散是其根本原因（指代疗法）。
烧香供养龙树菩萨，
祈求来世获得清净根源。

This text describes the symptoms, contraindications, and treatment methods for two types of external eye disorders.
First Condition: When this eye disease first occurs, the eyes may itch or hurt intermittently without a fixed pattern. During episodes, the eyes become red with visible blood vessels, tear profusely, and have excessive discharge (eye boogers), causing corneal opacities (cloudy patches) resembling cyanosis to appear horizontally or vertically on the black pupil (cornea). The number of these opacities varies. If left untreated for a long time, it causes severe damage, potentially leading to total loss of vision. This condition should not be treated with needle pricking or hook cutting. It is suitable to take Chongweizi San (Chenopodium Seed Powder), Chu Re Renshen Tang (Ginseng Decoction for Removing Heat), and apply Tuanyi Qingliang San (Clearing Heat and Dissolving Opacity Cool Powder) topically for immediate recovery.
Poem says:
Cyan blemishes appear horizontally and vertically on the cornea,
Like dense opacities, varying in quantity.
Physicians examine such appearances carefully,
When the root sinks deep into the cornea, do not prick or rub.
Worry that old age will bring further ailments,
Medicines that clear heat and wind are best.
Daily activities are fine, but treatment must be cautious,
Devote yourself to medical therapy, there is no other way.
Chongweizi San (Chenopodium Seed Powder)
Ingredients: Chenpi Zi (Herba Leonuri, 茺蔚子), Fangfeng (Radix Saposhnikoviae, 防风) (each 2 liang); Heishen (Radix Panacis Japonensis Rubra, 黑参), Xixin (Radix Asari, 细辛), Dahuang (Radix et Rhizoma Rhei, 大黄), Zhike (Fructus Aurantii, 枳壳), Zhimu (Rhizoma Anemarrhenae, 知母), Mangxiao (Natrii Sulfas, 芒硝) (each 1 liang); Shaoyao (Radix Paeoniae Alba, 芍药) (1.5 liang).
Preparation and Administration: Grind the above ingredients into powder. Take one qian of powder, add one zhan of water, boil until reduced to half volume, strain while warm, and take after meals.
Chu Re Renshen Tang (Ginseng Decoction for Removing Heat)
Ingredients: Renshen (Radix Ginseng, 人参), Fuling (Poria, 茯苓), Wuweizi (Fructus Schisandrae Chinensis, 五味子), Jiegeng (Radix Platycodonis, 桔梗), Dahuang (Radix et Rhizoma Rhei, 大黄), Heishen (Radix Panacis Japonensis Rubra, 黑参), Huangqin (Radix Scutellariae, 黄芩), Cheqianzi (Semen Plantaginis, 车前子) (each 1 liang); Huangqin (Radix Scutellariae, 黄芩), Zhimu (Rhizoma Anemarrhenae, 知母) (each 2.5 liang). *Note: Huangqin appears twice in the source text with different dosages; listed as per original.*
Preparation and Administration: Grind the above ingredients into fine powder. Take one qian of powder, add one zhan of water, boil until reduced to half volume, strain while warm, and take after meals.
Qingliang San (Cooling Powder for Dissolving Opacities)
Ingredients: Mayaxiao (Natrii Sulfas Crystallinus, 马牙硝), Baifan (Alumen, 白矾), Zengqing (Azurite, 曾青) (each 1.5 liang); Longnao (Borneolum Syntheticum, 龙脑), Qingdai (Indigo Naturalis, 青黛) (each 1 fen).
Preparation and Administration: Pound and grind the above ingredients into a fine, uniform powder. At bedtime, apply a small amount (half-zhi size) of dry powder directly into the eye.
Second Condition: When this eye disease first occurs, there is occasional pain. This is caused by toxic wind rushing upward into the brain and accumulated heat residing between the liver and diaphragm. This results in jade-colored opacities forming in the eye, completely covering the pupil. Such conditions are not suitable for acupuncture, cutting, moxibustion, or cauterization. It is suitable to take Tuiyi San (Opacity-Dissolving Powder) for immediate effect.
Poem says:
Jade-colored clouds float above the cornea,
Remaining roots linger after ulceration.
Apply ointments and powders to polish away opacities,
Bow to divine physicians seeking miraculous cures.
Take medicine to treat wind and remove heat,
Huajing Wan and San are the key remedies.
Burn incense to honor Bodhisattva Nagarjuna,
Seek pure roots for the next life.
Tuiyi San (Opacity-Dissolving Powder)
