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 eyeball is often damaged at the same time.

The eyelid is an appendage of the eye, which is the protective barrier of the eyeball. The defect of the eyelid, regardless of the weight of the defect, affects the shape, and more importantly, the defect will cause the eyeball to lose protection.

Differential diagnosis

Iris defect: If the choroidal fissure is not completely closed at the iris, the defect under the iris is caused, causing the circular pupil to be a keyhole, called the iris defect. Such malformations can extend to the ciliary body, retina, and optic nerve, often with limited other abnormalities.

Eyelid malformation: Eyelid deformity is caused by trauma, infection, tumor resection and other reasons. After scar contracture, it can cause abnormality of eyelid axillary shape, eyelid valgus and insufficiency.
