Wherever the red vessels (hyperemia of conjunctival blood vessels) and nebulae (corneal opacity) initially develop from top to bottom, it belongs to the Taiyang (Greater Yang) channel. Since the Taiyang channel governs the exterior, the pathology must involve pain in the supraorbital ridge, or pain at the vertex of the head, or swelling and pain on one side of the head. The treatment should employ warming and dispersing methods. Wherever the red vessel nebula develops from bottom to top, or spreads from the interior to the exterior, it all belongs to the Yangming (Yang Brightness) channel. Since the Yangming channel governs the interior, the symptoms often present as heat syndromes or solidified stool (constipation). The treatment should employ purgative and cooling methods. Wherever the red vessel nebula initially invades from the exterior to the interior, it is governed by Shaoyang (Lesser Yang), which controls the half-exterior and half-interior. The treatment should employ harmonizing methods. Nebulae occur when wind-heat pathogenic factors are severe, or when macules enter the eye; this indicates that Liver Qi is exuberant and the disease manifests on the exterior. Since the nebula forms on the exterior, it is clear that dispersing and eliminating methods should be used. If one instead uses draining and purging methods, the pathogenic factor will retract inward, causing the nebula to become deeper. When the pathogenic factor is unsettled, it is called "Heat Nebula" and is superficial; when the pathogenic factor has settled, it is called "Water Nebula" and is deep; when the pathogenic factor is firm and deep, it is called "Sunken Nebula." One should use dispersing agents to agitate the pathogenic factor again so that the nebula floats up, then assist with anti-nebula drugs to allow it to disappear naturally. For chronic conditions, rapid effects cannot be expected; gradual elimination over months and years is appropriate. For newly formed nebulae, Dongyuan's Qianghuo Chuyi Decoction (Notopterygium and Rhizoma Ligustici Decoction for Removing Nebulae) can be used for exterior dispersal; for heat syndromes, Tuī Yún Wán (Cloud-Dispersing Pill) and similar formulas may be used; for dispersing sunken nebulae, Lingyangjiao San (Antelope Horn Powder) from *Baoming Ji* (Collection Preserving Life) can be used. Application depends on careful consideration. For those with Yin deficiency and heat, Shenxian Tuī Yún Wán (Immortal Cloud-Dispersing Pill) should be taken concurrently.

The condition of Yellow Membrane Rushing Upward is most authentic. Within Fengyun Gao (Wind-Cloud Ointment), yellow clouds arise. Located deep within the boundary between the white sclera and black cornea, they directly flood the pupil from the Kan position (associated with the Kidney/pupil). This is due to constipation, and headache is the worst symptom. Meridians are often obstructed, with fire, dryness, astringency, and inflammation steaming upward. Mistaking Yongbo Yi (Wave Ripple Opacity) for this condition will only result in blurred vision.

This syndrome occurs at the lower margin of the Wind Wheel (black cornea), between the Kan positions, initially appearing yellow within the Shen Gao (internal ocular fluids/tissues), resembling the white rock at the root of a human fingernail. In cases of Nourzhi Yi (Congealed Fat Opacity), the congealed fat originates outside the wheel, and topical medication can remove it. However, this condition lies within the internal tissues, where topical medication cannot reach. If it spreads to the pupil, the eyeball will inevitably rupture. It must not be mistaken for Yongbo Yi for treatment. This is caused by extreme obstruction of meridians, Guan Ge (blockage of upper and lower passages) of the San Jiao (Triple Burner), and excess of Fire and Earth pathogenic factors. Consequently, there is constipation and urinary retention, leading to the steaming of internal fire into pus. If the upward rush is untreated, complications such as protruding eyes (exophthalmos) will certainly occur. The following formula is suitable:

Tongpi Xiewei Tang (Splea-Clearing and Stomach-Purging Decoction): This syndrome is extremely adverse and cannot be cured by a single formula alone. One must investigate the deficiency or excess indicated by the pulse and prescribe formulas according to the specific etiology.
Ingredients: Maidong (Ophiopogonis Radix, heart removed), Chongweizi (Ecliptae Fructus) (each 1.5 qian); Zhimu (Anemarrhenae Rhizoma), Xuanshen (Scrophulariae Radix), Cheqianzi (Plantaginis Semen), Shigao (Gypsum Fibrosum), Fangfeng (Saposhnikoviae Radix) (each 1 qian); Huangqin (Scutellariae Radix), Tiandong (Asparagi Radix), Dahuang (Rhei Radix et Rhizoma, prepared) (each 0.7 qian).
Process: Cut into pieces. Decoct in two zhong of plain water until reduced to eight fen. Take after meals. For severe heat, add Xuanmingfen (Mirabilite) 1 qian.

Liying San (Instant-Efficacy Powder): Treats internal and external nebulae, blurriness and astringency with excessive tearing, acute red eye, and all types of eye diseases. Administer via nasal insufflation three times.
Ingredients: Euphorbiae Hirtae Herba (cleaned, dried), Baizhi (Angelicae Dahuricae Radix, washed), Danggui (Angelicae Sinensis Radix, whiskers removed, washed), Yangzhizhu Hua (Rhododendri Mollis Flos, halved), Chuan Fuzi (Aconiti Lateralis Radix Praeparata, processed, skin and umbilicus removed), Xionghuang (Realgar) (separately ground and added later) (equal parts).
Process: Grind into a fine powder. Add a small amount of Shexiang (Moschus) and mix evenly. Hold water in the mouth, instill into the nose, until turbid discharge and tears are completely expelled.
