What are the types of ptosis in Wuhan?

Ptosis, commonly known as large eyelids, is an eye deformity. People with ptosis often feel like they are unable to wake up. Ptosis refers to the insufficiency or loss of function of the levator palpebrae superioris muscle (innervated by the oculomotor nerve) and smooth muscle (innervated by the cervical sympathetic nerve), resulting in partial or complete drooping of the upper eyelid. In mild cases, part of the pupil is covered, and in severe cases, the entire pupil is covered. , not only hinders the appearance and affects vision, but also can cause severe amblyopia in congenital cases, which must be paid attention to.
Types of ptosis
Eyelid ptosis is mainly caused by congenital and acquired causes. While congenital ptosis accounts for all categories, acquired ptosis can be divided into the following types according to its cause:
, Sympathetic palsy ptosis
It is a partial symptom of sympathetic palsy, mostly Seen in neck surgery, trauma, and thyroid patients. It manifests as mild ptosis of the upper eyelid, a slightly higher position of the lower eyelid to form a small palpebral fissure, retraction of the eyeball, and miosis of the pupil, constituting the syndrome.
Mechanical ptosis
It is caused by the pathological changes of the eyelid itself, such as tumors, amyloidosis, severe trachoma, inflammatory edema, trauma, tissue proliferation (elephaniasis), etc. In addition to direct damage to the levator palpebrae superioris muscle, the disease also causes eyelid hypertrophy, resulting in mechanical ptosis. There is also a type of ptosis of unknown cause, namely senile myopathic ptosis, which is caused by primary muscle atrophy and is bilateral. It is more common in elderly women.
, Oculomotor nerve palsy ptosis
It is caused by damage to the oculomotor nerve or nerve nucleus, usually unilateral, often accompanied by eye movement disorders, and sometimes diplopia.
, Myogenic ptosis
Common in myasthenia gravis and progressive external ophthalmoplegia, ptosis caused by myasthenia gravis, the degree increases with fatigue, and is lighter in the morning. Aggravated at night and when tired.
Pseudoptosis means that the upper eyelid appears to be drooping in appearance, but the function of the levator palpebrae superioris muscle is normal upon objective examination, and the true position of the upper eyelid is also normal. It is common in upper eyelid skin laxity, lack of support for the upper eyelid, and idiopathic idiopathic ptosis. Blepharospasm.
