Introduction The valgus is the lower palpebral conjunctiva that flips outward, causing the eyelid to not be in close contact with the eyeball, and the cleft palate is incompletely closed. The palpebral conjunctiva is prone to chronic conjunctivitis due to long-term exposure after valgus, resulting in increased secretions, dry membrane, hypertrophy and hyperemia. Upper eyelid valgus, due to corneal exposure is easy to occur with keratitis and corneal trauma, resulting in decreased vision, and even blindness. The chin is everted, because the tears can not be closely attached to the eyeball, causing tears. Even if it is a mild valgus valgus, the function damage is not heavy, and it needs to be corrected because the appearance is not beautiful.

Cause

1, scarring: due to eyelid trauma, burns, eyelid ulcers, sacral osteomyelitis or improper operation of the ankle, etc. caused by skin scar traction.

2, sputum: due to eyelid skin tension, content filled with orbicularis tendon ( ( ( ( ( ( Common in children with vesicular keratitis, or patients with high eyeballs.

3, paralytic: only seen in the lower jaw, due to facial nerve paralysis, orbicularis muscle contraction loss, the lower jaw according to its own weight, the vertical surface of the vertical formation.

4, senile: only seen in the lower jaw, because the elderly's orbicularis function is weakened, the eyelid skin and the external iliac ligament are also loose, so that the gingival margin can not cling to the eyeball, and eventually the squat is falling due to the weight of the squat. In addition to tears caused by eversion, chronic conjunctivitis, the patient frequently rubbed the tears down, increasing the degree of eversion.

Vision conjunctival examination

(1) Tears occur due to the small valgus of the tears.

(2) The conjunctiva of the exposed part becomes hyperemia, hypertrophy, dry, rough, and even epidermal-like changes.

(3) Severe cases can lead to hernia closure and exposed keratitis.

Clinical manifestations:

(1) Mild: only the gingival margin leaves the eyeball, but tears overflow due to the capillary action between the eyelid and the eyeball.

(2) Severe: valgus valgus, part or all of the sacral conjunctiva exposed, so that the palpebral conjunctiva loses the tears of the wet, initially localized congestion, increased secretions, long dry and rough, highly hypertrophic, showing a horn. The squatting of the squat can leave the tear lake at the tears, causing tears. More research, valgus valgus often has eyelid regurgitation, the cornea loses protection, corneal epithelium dry and fall off, easily lead to exposed keratitis or ulcers.

Differential diagnosis

The disease should be differentiated from the wind-induced phlegm: both have eyelid valgus, but the wind is mostly limited to the lower jaw, and there is no scar; and the disease is caused by the sputum self-injury, which is caused by scar contraction. Eyelids can occur. The wind pulls out more due to the accumulation of heat in the stomach, and the liver wind is full, which causes the wind and damp heat to attack, caused by qi stagnation and blood stasis. Because the chord is turned over, the eyelids cannot be closed, and the eye is often dry and sore, and even keratitis occurs. More often in the lower jaw.
