congenital eyelid defect
Introduction
Introduction to congenital eyelid defect Congenital eyelid defects are rare congenital anomalies. Animal experiments have shown that X-ray irradiation and injection of choline or naphthalene during the embryonic period, the second generation can occur orbital defects, congenital cataract and small eyeballs. Some patients have a history of blood marriage. There are reports of mother and daughter, or brothers suffering from this disease at the same time. Surgical repair to protect the cornea or improve the face. The congenital giant eyelid defect was repaired by skin skating flap and allogeneic sclera stratification. The method of stratified repair of huge orbital defect was designed. The local metastasis of the conjunctival flap was used to repair the conjunctival surface. The allogeneic sclera was used to replace the tarsal plate. The skin layer was repaired with the defect area extension incision and the nasal side sliding sliding flap to achieve the first-stage repair of the full-thickness eyelid. The purpose of the defect. basic knowledge Sickness ratio: 0.0012% Susceptible people: no special people Mode of infection: non-infectious Complications: eyelid closure, allergic eyelid dermatitis
Cause
Congenital eyelid defect cause
Congenital factors (54%):
It refers to the factors that can be caused by humans before birth, including hereditary and congenital pathogenic factors in Western medicine. The pathogenic characteristics of congenital pathogenic factors are mainly affecting the growth and health of children, leading to the occurrence of certain hereditary diseases or congenital diseases. Traditional Chinese medicine generally divides congenital factors into two aspects: fetal weakness and fetal toxicity. Such as Qing Chen Fuzheng "young and young integration" said: "Children are sick at birth, but only weak, fetal toxicity."
Prevention
Congenital eyelid defect prevention
Pregnant women should be checked regularly during pregnancy to prevent their birth.
There are two types of congenital defects: congenital and acquired. Congenital defects can occur in the upper and lower jaws, unilateral or bilateral, often accompanied by deformities of the temple, lacrimal duct, eyebrows or frontal and maxillary defects. Normal vision. Or have obstacles. Acquired defects are usually caused by trauma (such as car accidents, gunshot wounds, bites, etc.), and the eyeballs are often damaged at the same time.
The eyelid is the appendage of the eye, which is the protective barrier of the eyeball. The defect of the eyelid, regardless of the severity of the defect, affects the shape. More importantly, the defect will cause the eyeball to lose protection.
Complication
Congenital eyelid defect complications Complications, eyelid closure, allergic orbital dermatitis
Can be complicated by eyelid closure, allergic eyelid dermatitis.
Symptom
Congenital eyelid defect symptoms Common symptoms Iris defect Orbital malformation Corneal surface triangle fat
Most of them are single eyes, and those who occur in the upper jaw are more common. The defect site is dominated by the central medial side. The shape of the defect is mostly triangular, and the base is located at the rim. But there are also trapezoidal or elliptical. If the defect is large, the cornea may lose its protection and cause dryness or infection.
This disease can also be accompanied by congenital anomalies in the eye and other parts of the body, such as permanent pupillary membrane, pupil ectopic, iris, choroidal defect, symblepharon, small eyeball, cleft palate, cleft lip, facial fissure, abdominal hernia, etc. Less common.
If the defect occurs on the lateral side of the lower jaw, it is often accompanied by ipsilateral tibial dysplasia.

Diagnosis
Diagnosis and diagnosis of congenital eyelid defect
Diagnostic criteria: typical congenital eyelid defects are mostly triangular, with the base facing the rim and quadrilateral. Can be accompanied by congenital anomalies in the eye and other parts of the body, such as permanent pupillary membrane, pupil ectopic, iris, choroidal defect, symblepharon, small eyeball, cleft palate, cleft lip, facial fissure, abdominal hernia, etc., but less common . If the defect occurs on the lateral side of the lower jaw, it is often accompanied by ipsilateral tibial dysplasia.
A diagnosis can be made based on the above clinical manifestations.
