eversion of the eyelid
Introduction
Introduction Eyelid valgus is an abnormal state in which the rim leaves the eyeball and flips outward. The lighter is caused by the eyeball leaving, the severer is exposed to the conjunctiva, and even the eyelids are all everted. Eyelid valgus means that the eye edge is turned outwards and turns away from the eyeball. The conjunctiva can be exposed to varying degrees. In the elderly, the function of the orbital muscles is weakened, the eyelid skin and the external iliac ligament are also relaxed, so that the eyelids can not only stick to the eyeball, and the lower jaw weight causes the fall, and the lower jaw weight causes the fall.
Cause
Cause
The cause of eyelid valgus:
Eyelid valgus can be divided into three categories:
1. Skin scars can be caused by trauma, burns, chemical injuries, eyelid ulcers, blepharospasm or facial surgery.
2. In the elderly, the function of the orbital muscles is weakened, and the eyelid skin and the external iliac ligament are also relaxed, so that the eyelids can not only stick to the eyeball, and cause the lower eyelid to fall.
3. In facial nerve paralysis, the contraction function of the orbicularis muscle is lost, and it occurs due to the weight of the lower jaw.

Examination and diagnosis of eyelid valgus:
Eyelid valgus can occur on one side of the upper or lower jaw, or both sides of the upper and lower jaws. After the eyelid valgus can be secondary to keratitis, resulting in symptoms such as fear of light, tearing and dry eyes. Eversion of the eyelids, due to chronic conjunctival inflammation, resulting in hypertrophy of the conjunctiva and tarsal plate, growth of the palpebral margin or destruction of the palpebral margin, blepharitis, lashes, etc., long-term exposure of the cornea is prone to secondary keratitis, corneal ulcers and white spots , seriously affecting vision, and even leading to blindness.
Diagnosis
Differential diagnosis
Symptoms of eyelid valgus confusing:
1. Eyelid relaxation: blepharochalasis syndrome, also known as dermatolysis palpebrarum, atrophic eyelid ptosis (ptosis atrophica), is a rare eyelid disease characterized by recurrent episodes of eyelid edema in adolescents The skin of the eyelids becomes thinner, the elasticity disappears, the wrinkles increase, the color changes, and the clinical manifestations of lacrimal gland prolapse, ptosis and shortening of the cleft palate can be complicated. In 1807, Beer first described the disease. In 1896, Fuchs called it eyelid retardation. Because the syndrome affects the appearance of the eyelids, it is the main reason for patients to require treatment. The understanding of their clinical manifestations and pathogenesis can help to adopt appropriate methods for treatment.
2. Eyelid drooping: also known as "hanging down." Due to insufficiency or disappearance of the levator palpebral function, or some or all of the upper jaw can not be lifted, the upper jaw is in a drooping position. Divided into complete and partial, monocular or binocular, congenital and acquired, true and false.
