Introduction to Eversion valgus refers to the eyelids flipping away from the eyeball, and the conjunctiva is often exposed to varying degrees, often with cleft palate incomplete, and the lower jaw is more common than the palate. In the case of the light, the posterior lip of the iliac crest leaves the eyeball. If the valgus is involved in the palpebral palpebral valgus, it may cause tears. In severe cases, the conjunctiva is exposed, and even the eyelid is incompletely closed. valgus can be divided into four categories according to its causes: scar, paralysis, senile, and sputum. Chronic conjunctivitis occurs in the conjunctiva due to prolonged exposure after valgus, resulting in increased secretions, dry and thick conjunctiva and hyperemia. basic knowledge The proportion of illness: 0.02% Susceptible people: no special people Mode of infection: non-infectious Complications: keratitis

Cause of valgus

Senile (30%):

Only seen in the lower jaw, due to the weakening of the orbicularis muscle function of the elderly, 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 lower jaw, and the eversion is caused by the eversion. The tears, chronic conjunctivitis, make the patient frequently rub the tears down, increasing the degree of eversion.

(25%):

Due to the tight skin of the eyelids, the contents of the eyelids are filled with the orbicularis tendon and the upper edge of the tarsal plate (the lower edge of the lower jaw). It is common in children with vesicular keratitis, or patients with high ocular ocular protrusion. In the lower jaw, due to facial paralysis, the contraction function of the orbicularis muscle is lost, and the lower jaw is eversion due to its own weight.

Scarring (25%):

It is caused by scarring of the skin caused by eyelid trauma, burns, eyelid ulcers, osteomyelitis of the tibia or improper operation of the ankle.

Eversion prevention

Generally, eye correction surgery is performed. First, the diaphragm is tightened, the orbicularis muscle is lifted, and the excess skin is removed. However, some doctors mistakenly correct the eye bags and think that the skin is tightened and neglected. The tightening of the diaphragm and the orbicularis muscle, such as the appropriate amount of skin removal, and the untreated diaphragm and the orbicularis muscle, the eye bags will recur quickly, if the skin is removed too much, it will be suitable for valgus valgus, recent In the year, many scholars agreed that the corrective operation of the eye bags, the strengthening of the septum, and the lifting of the orbicularis muscles are more important than the skin removal.

Ectopic valgus complications Complications keratitis

It usually occurs as a serious complication of eye bag correction surgery.

1, due to tears small valgus, tears occur.

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.

valgus inspection

After the eyelids are everted, the gingival margin leaves the eyeball, the palpebral conjunctiva is dry and hypertrophy, the surface is congested, the cornea is also dry, the ulcer is formed, and eventually scars are formed, which impairs vision.

valgus 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.
