障膜有时聚拢、有时散开，湿热郁结于脑部，浑浊如云雾遮蔽月亮，张开眼睛看星星觉得变小。发作时疼痛且涩滞感多，消退后视力也不佳，来去如同浮萍的痕迹，治疗不可草率。
此症像翳又不是障，形状或圆或缺。疼痛时就显现，不痛就隐没，出现和消失没有定时，聚集和消散不一致，因此称为“浮萍”。大概原本患有风痰引起的头痛，被庸医误治，导致虚实错乱（虚者更虚，实者更实），致使元气受损，而病邪并未去除。庸医只知道补其虚损，不敢攻其实邪，因此湿热深潜于脑户，遇到岁气不和以及人事刺激，就会触发祸患。性情柔和的人常一季发作数次，性情刚急的人一月发作数次不等。虽然不吃药也能痊愈，但始终留下成为顽固疾病。医生应当采取彻底清除病根的方法，同时灵活变通以顺应人情，病根才能断绝。
以上四种病症，都是病程长久，攻散的治疗方法不必多讲。切按脉象，询问邻近环境，以及喜好厌恶、大小便情况，使用越鞠丸、逍遥散、疏肝散、菊花茶调散等方剂，配合拨云丹、补心丹、还少丹，再用固本人参汤，根据情况增减生地黄和熟地黄的分量，用丹药点眼消除障膜，用刀术去除瘀血。虽然主攻方向像嘉言先生那样，但绝不违背医门法律。
凡是黑翳，都有来由，巽震之风雷惨烈难以收拾，不要埋怨老天吝啬薄命，这其中的原因本来就不像苍蝇头那样微小。
此症初起轻微瘙痒，继而涩滞，随后疼痛如针刺。日久则红肿流泪，畏光长时间闭眼。风轮（黑睛）上浮起一片翳，黑色而圆，大小高低不等，形状像蟹的眼睛，然而并不是因为黑睛破损而得的。而且内外夹攻，才叫作蟹睛。不知不觉自行脱落，脱落后再进行调理，不留痕迹。怒不能发，饮食不宜，病候如前，需预防一二。
此症少见，平生只遇到过一位贫家子弟，形体瘦弱却能劳作，患病如此，仍像拾柴卖草一样，辛苦如常。我怜悯他，赠送给他四君子汤加山茱萸、酒炒黄连，疼痛停止并能睁开视物。再服用，感觉翳膜变得焦枯缩小。于是去掉黄连，加入白芍、麦冬、牛蒡子，未服满三剂，眼睛平复如初。又给予助脾蜜饼子四两，完全康复。然而这也是偶然中的。恐怕那些膏粱壮汉，必须依据蟹睛在未服药未破溃时的治法。
The opacity (obstruction) sometimes gathers and sometimes disperses; damp-heat stagnates in the brain, turbid like clouds covering the moon. When opening the eyes to view stars, they appear small. Upon onset, there is much pain and astringency; after it passes, vision remains poor. Its coming and going resembles traces of duckweed; treatment must not be hasty.
This condition resembles an opacity (nebula) but is not a true obstruction. It may be round or irregular. It appears when painful and hides when painless, appearing and disappearing without fixed timing, gathering and scattering inconsistently, hence named "Floating Duckweed" (Fuping). Generally, the original ailment was headache due to wind-phlegm. A quack doctor mismanaged it by exacerbating both deficiency and excess (deficiency made deficient, excess made excessive), causing damage to Yuan Qi (Primordial Qi), while the pathogenic factor remained. The mediocre physician knew only to tonify the deficiency but dared not treat the excess, thus allowing damp-heat to sink deeply into the Brain House (Naohu). When the annual climate is discordant or triggered by emotional/interpersonal stimuli, the disaster erupts. Those with gentle temperaments may suffer several episodes per season; those with irritable temperaments may suffer several times per month. Although it may heal spontaneously without medication, it ultimately becomes a chronic stubborn disease. Physicians should employ methods to thoroughly cleanse the pathology ("伐毛洗髓" - plucking hair and washing marrow, implying radical cure), flexibly adapting to human circumstances, so that the root of the disease is eradicated.
For the above four conditions, which have persisted for a long time, aggressive dispersal methods need not be discussed. Palpate the pulse, inquire about the immediate environment, preferences/dislikes, and urination/defecation. Use formulas such as Yueju Wan (Yueju Pill), Xiaoyao San (Free and Easy Wanderer Powder), Shugan San (Soothe Liver Powder), Juhua Chatiao San (Chrysanthemum Head-Tying Powder), Buyun Dan (Cloud-Piercing Elixir), Buxin Dan (Heart-Nourishing Elixir), and Huanshao Dan (Rejuvenating Elixir). Subsequently use Renshen Guben Tang (Ginseng Root-Fortifying Decoction), adjusting the dosages of Sheng Dihuang (Raw Rehmannia Root) and Shu Dihuang (Prepared Rehmannia Root) according to circumstances. Apply medicinal drops to remove opacities and use surgical incision to remove blood stasis. Although the primary approach follows that of Jiayan, one must strictly adhere to medical laws and ethics.
All cases of Black Opacity (Heiyi) have their origins. The fierce winds and thunder of Xun and Zhen are unbearable; do not blame Heaven for being stingy with your fate. The cause here is not trivial like a fly's head.
This condition begins with slight itching, progresses to astringency, and then becomes piercing pain. After a long time, redness, swelling, tearing, photophobia, and prolonged eye closure occur. An opacity floats up on the Wind Wheel (Cornea/Black Eye), black and round, varying in size and height, resembling a crab's eye, yet it is not caused by a rupture of the wheel. Furthermore, internal and external attacks combined constitute what is called "Crab Eye." It falls off unnoticed; after falling off, further management leaves no trace. Anger should not be vented, diet should be appropriate, and precautions should be taken regarding the aforementioned symptoms.
This condition is rare; I encountered only one poor boy in my life who was emaciated yet capable of labor. Suffering from this illness, he continued to gather firewood and sell grass, working hard as usual. Out of pity, I prescribed Sijunzi Tang (Four Gentlemen Decoction) augmented with Cornus officinalis (Shanzhuyu) and Coptidis Rhizoma (Huanglian) stir-fried with wine. The pain ceased, and he could open his eyes to see. Upon further administration, the opacity appeared scorched and shrank. I then removed Huanglian and added Paeoniae Radix Alba (Baishao), Ophiopogonis Radix (Maidong), and Arctii Fructus (Niubangzi). Before completing three doses, the eye returned to normal. I also gave him Sizhu Bingzi (Assisting Spleen Honey Cakes), four liang, resulting in complete recovery. However, this was merely a lucky coincidence. For robust men accustomed to rich diets, one must follow the treatment methods for Crab Eye before medication and before rupture.
