Is droopy eyelid disease? What are the causes of droopy eyelids?

Most of the eyelid drooping is caused by the aging of ZD, eyelid **, muscle relaxation, and relatively light drooping generally has no effect on the eyeball and can be left untreated. As we age, sagging may worsen, which can cause difficulty in opening the eyes, and vision may decrease when the pupils are occluded, which can also affect the person's appearance. Lifting or blepharoplasty can be done.

Some patients may also be caused by long-term eye focus and eye rubbing** relaxation of eyelid muscles, or it may be caused by repeated conjunctivitis. Congenital ptosis and epicanthal folds can also cause ptosis, which can also be corrected surgically. Some patients may have ptosis caused by muscle weakness, and can be treated with **myasthenic drugs**.

There are also oculomotor nerve palsies that require neurology**.

Congenital ones are mostly related to heredity, and are characterized by autosomal dominant or recessive inheritance. Oculomotor or levator palpebrae muscle dysplasia is common**, with abnormal contractile and diastolic function of muscle fibers.

Acquired disease can be caused by lesions of the eyelid itself, or by neurological and other systemic lesions, and common causes include oculomotor palsy, levator palpebra injury, sympathetic disorders, myasthenia gravis, inflammatory swelling of the upper blepharopla, or neobiotics.

Familial inheritance: Parents with ptosis.

Ocular trauma: Engaging in dangerous work or accidentally injuring the muscles and nerves of the eye.

Eye surgery injuries, cosmetic operation accidents.

Presence of underlying neurological disorders, such as brain tumors, multiple sclerosis.

Presence of underlying diseases of the muscular system, such as myasthenia gravis, myotonic syndrome, progressive muscular dystrophy, etc.

Age factor: Older people may develop degenerative changes in ocular tissue.

Droosis eyelids are medically called ptosis. Ptosis is a condition in which the upper eyelid is partially or completely ptosis due to levator palpebrae muscle insufficiency, or related neurological insufficiency, covering part or all of the pupil. It is divided into two types:

1. Congenital: congenital at birth, generally bilateral. If it is caused by simple levator palpebrae hypoplasia, it is simply ptosis. If it is due to neurodevelopmental hypoplasia, in addition to ptosis, it is accompanied by other ocular manifestations such as strabismus;

2. Acquired: Acquired nature is divided into four subcategories, the first type is ptosis caused by oculomotor nerve palsy, which generally causes the levator palpebrae muscle to be unable to lift and the eyelids to be lifted due to oculomotor nerve palsy, resulting in ptosis. The other is ptosis caused by sympathetic paralysis, which is mostly caused by neck trauma surgery.

The third subcategory is myogenic ptosis, which is more common in myasthenia gravis, characterized by mild morning and twilight and severe at dusk, and with subcutaneous and intramuscular neostigmine injections, the symptoms will improve. The fourth type is mechanical ptosis, which is mostly caused by the eyelid itself, such as eyelid tumors or acute inflammation of the eyelids, which cause the eyelids to swell and cannot be lifted.

There are two options for this.

One is laxity, which leads to sagging.

There is also muscle weakness, which cannot support the weight and will sag.

Ptosis refers to ptosis, which is the insufficiency or loss of the levator palpebrae muscle, or the inability to lift part or all of the upper eyelids due to other reasons, resulting in difficulty in opening the eyes, occluding part or all of the pupils, and making it difficult to open the eyelids completely or partially. It can be divided into congenital ptosis and acquired ptosis.
