地廓倾翻形最恶，血泪洋洋廓上搁。若使伊芳来惊小儿，不须两手下攀着。合前弦睑烂难堪，总号残风治无药。
此症乃目下维倾缩，内睑绚烂于外，有若人翻转而致者。盖气逼血拥，而又乘以风湿，遂筋拽皮急，能下而不能
返。甚则赤烂，多眵与泪，本科呼为残风。风痰好酒人，往有患者，治亦难愈。非风暴得，有肿有疼，清胃散、
泻黄散、
甘露饮治其内，砭且洗治其外。内外兼理，抑又不难。若轮廓已坏，病楚俱除，但照镜自觉可羞，殆将有事风鉴，
医无庸议。
杨子泣逵途，为其可南北。墨子悲 丝，为共可黄黑。稚子何所伤，开襟泪沾臆。有若哭相思，青青转成碧，
又如惜别离， 不忽滴。发我抒愫居，参苓作汤液。露稀金风肃，清欢邈难即。
此症目内外轮廓无恙，但泪稠如浊酒豆浆，长流而不止也。间有睑肿紧合，强攀则激而溅出。时医以为脓汁，
莫识所自。且小儿患此居多，无以为治。讵知清肺理脾，治之亦易易耳。或问故，曰∶肺非无为也，主降下之令
焉。凡人饮食入胃，脾气散精，上归于肺，肺不和则不能通调水道灌溉百骸，遂溢于高源，淫入皮肤，为肿为湿。
加以木火上升，曲直作酸，则水凝而浑，愈无从而渗泄，乃就其所属，出于气轮曰眵泪。由此言之，病固不在肝
而在脾，不在脾而在肺也。久而不痊，恐脾肺俱困，懒于运精化气，则神水内枯，保得长年目光终乎不亮。治法，
小儿只六君子加柴胡、白芍药。再则去柴、芍，加麦冬、五味子，服数剂立住。男妇用白菊清金散、九仙丸，脉
形俱虚者，归 六君子、补中益气加附子、防风、五味、白芍亦妙。
此症目科常有，诸书无一语讲及，何也。
The eyelid margin is inverted, presenting the most unsightly appearance, with tears and blood pooling upon the lid. If this sight were to startle a child, there would be no need to use both hands to forcibly pull the eyelids down. Combined with the previously mentioned unbearable ulceration of the eyelids, it is collectively termed "Can Feng" (Residual Wind), which was historically considered incurable.
This condition arises from the laxity and inversion of the lower eyelid's supporting structures, causing the inner palpebral conjunctiva to evert externally, resembling a manual turning inside out. This is caused by qi forcing blood stasis, compounded by wind-dampness pathogenic factors, leading to tendon traction and skin tightness, allowing downward eversion but preventing retraction. In severe cases, redness and ulceration occur, accompanied by excessive discharge (discharge) and tearing. The ophthalmology specialty calls this "Can Feng." It often affects individuals prone to phlegm-wind and alcohol consumption; historically, such patients were difficult to cure. If not caused by traumatic wind-storm injury, and without significant swelling or pain, internal regulation can be achieved with Qingwei San (Stomach-Clearing Powder), Xiehuang San (Yellow-Draining Powder), or Ganlu Yin (Sweet Dew Decoction), while external treatment involves scarification (Bian therapy) and washing. Treating both internally and externally is actually not difficult. However, if the eyelid contour is already deformed, although the pain and suffering are removed, the patient may feel ashamed when looking in the mirror, likely facing social stigma, rendering medical advice superfluous.
Yang Zhu wept at the crossroads because paths could lead north or south. Mozi grieved over dyed silk because it could be turned yellow or black. What injury befell the child, causing tears to soak his chest as he opened his robes? Like one crying out lovesickness, dark hair turning green [metaphor for extreme sorrow], or mourning parting, tears dropping incessantly. To express my feelings, I prepare a decoction of Ginseng Radix et Rhizoma (Renshen) and Poria (Fuling). As dew thins and autumn winds chill, pure joy remains distant and hard to attain.
This condition presents with normal eyelid contours internally and externally, yet the tears are thick and turbid like sour wine or soy milk, flowing continuously. Occasionally, the eyelids swell and close tightly; forcibly opening them stimulates a spray of tears. Contemporary physicians mistook this for pus, failing to identify its origin. Moreover, children suffer from this frequently, yet lacked effective treatments. Little did they know that clearing the lung and regulating the spleen makes treatment quite easy. When asked for the rationale, the answer is: The Lung is not inactive; it governs the descending directive. When food enters the stomach, the Spleen disperses essence upward to the Lung. If the Lung is disharmonious, it cannot regulate water passages and irrigate the body, causing fluid to overflow from high sources, infiltrate the skin, and cause swelling and dampness. Furthermore, with Liver Wood and Heart Fire rising, producing acidity, the water condenses and becomes turbid, hindering permeation and excretion. Consequently, following its associated pathways, it exits via the Qi Wheel (White Eye/Conjunctiva) as discharge and tears. Thus, the disease root lies not in the Liver, but in the Spleen; not in the Spleen, but in the Lung. If unresolved for a long time, both Spleen and Lung may become exhausted, failing to transport essence and transform qi, leading to the internal depletion of Shen Water (ocular fluid). While longevity might be preserved, vision will ultimately dim. Treatment for children involves Liu Jun Zi Tang (Six Gentlemen Decoction) added with Bupleuri Radix (Chaihu) and Paeoniae Radix Alba (Baishao). Subsequently, remove Chaihu and Baishao, add Ophiopogonis Radix (Maidong) and Schisandrae Fructus (Wuweizi); after a few doses, tearing stops immediately. For men and women, Baiju Qingjin San (White Chrysanthemum Metal-Clearing Powder) or Jiuxian Wan (Nine Immortals Pill) are used. If pulses are deficient, Liu Jun Zi Tang modified, or Buzhong Yiqi Tang (Middle-Wardening Qi-Supplementing Decoction) added with Aconiti Lateralis Radix Praeparata (Fuzi), Saposhnikoviae Radix (Fangfeng), Wuweizi, and Baishao is also excellent.
This condition is common in ophthalmology, yet no previous medical texts mention it. Why?
