eversion of lower eyelid
Introduction
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. The chin is everted, because the tears can not be closely attached to the eyeball, causing tears.
Cause
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.

(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.
Diagnosis
Differential diagnosis
1, scarring palpebral eyelids caused by skin lesions contraction. Skin scars can be caused by trauma, burns, chemical burns, eyelid ulcers, blepharospasm or facial surgery.
2, senile genital valgus is limited to the lower jaw. Because the function of the orbital muscles of the elderly 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 cause the lower eyelid to fall.
3, paralytic valgus is also limited to the lower jaw. Due to facial nerve paralysis, the contraction function of the orbicularis muscle is lost, and it occurs due to the weight of the lower jaw.
(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.
