What Are Eyelid Lesions?

Eyelids are commonly known as eyelids. It is divided into upper eyelid and lower eyelid, and when it is closed, it is covered in front of the eyeball to protect the eyeball. The gap between the upper and lower eyelids is called blepharoplasty. On the edges of the two eyelids near the corners of the inner eye, each has a punctum. There is a row of eyelashes on the edge of the eyelid, which can block the sand. The tissue structure of the eyelid is skin, subcutaneous tissue, muscular layer, meibomian and conjunctiva in order from the outside to the inside. Diseases that occur in the eyelid area are part of the systemic disease or local diseases. The diseased areas are the skin, eyelid glands, eyelashes, muscles, etc., including inflammation of the eyelid, trauma, tumors, and inversion and eversion of the eyelid. , Congenital deformities of the eyelids, etc.

Eyelid Diseases

Eyelids are commonly known as eyelids. It is divided into upper eyelid and lower eyelid, and when it is closed, it is covered in front of the eyeball to protect the eyeball. The gap between the upper and lower eyelids is called blepharoplasty. On the edges of the two eyelids near the corners of the inner eye, each has a punctum. There is a row of eyelashes on the edge of the eyelid, which can block the sand. The tissue structure of the eyelid is skin, subcutaneous tissue, muscular layer, meibomian and conjunctiva in order from the outside to the inside. Diseases that occur in the eyelid area are part of the systemic disease or local diseases. The diseased areas are the skin, eyelid glands, eyelashes, muscles, etc., including inflammation of the eyelid, trauma, tumors, and inversion and eversion of the eyelid. , Congenital deformities of the eyelids, etc.

Causes of eyelid lesions

The eyelid is located in front of the eyeball and is divided into upper and lower eyelids. The edge is called the eyelid margin, and there are eyelashes, openings of some glands and tear spots. The fissure between the upper and lower eyelids is called blepharoplasia. The junction of the two eyelids is called the inner condyle and the outer condyle. Histologically, the eyelid is divided into skin layer, subcutaneous tissue layer, muscle layer, fiber layer and conjunctival layer. Therefore, the whole body or local skin, mucous membrane, muscle and other lesions can spread to the eyelids. The main physiological function of the eyelid is to protect the eyeball. The closure of the upper and lower eyelids can prevent the invasion of microorganisms and dust from the outside, and the blink movement can evenly distribute the secretions of the glands on the surface of the eyeball, smooth the eyeball, and make the cornea have a normal luster. Eyelashes also block too much light from entering the eye.

Eyelid disease manifestations

Sometimes eyelid lesions are an early manifestation of systemic diseases, such as non-inflammatory edema of double upper eyelids in patients with nephritis; herpes simplex may occur in the eyelids when catching a cold; eyelids may be incompletely closed or spastic contractions during facial paralysis. However, most of the lesions are caused by the spread of itself or adjacent tissues, and the lesions of the eyelids can also spread to the eyeball, orbit, intracranial and even the whole body.

The most common eyelid lesions are inflammation, especially glandular inflammation. Such as blebitis, also known as stye, is an acute purulent infection of the meibomian glands or sebaceous glands. Hot compresses are usually given, and antibiotics can be applied locally or systemically. Remember not to squeeze, to avoid infection and flow from the valveless vein to the cavernous sinus or blood to the orbit.
