Droopy eyelids? Can’t keep your eyes open? The disease is always misunderstood

When it comes to “ptosis”, you may not understand it. Many people’s description of ptosis may be “sagging upper eyelids, unable to open eyes.” Today we will talk about it systematically How to spot ptosis and how to treat it.

01. What is ptosis?

We usually compare the eyes to a window, and the upper eyelid is like a curtain that can be pulled up and down.

But due to the weakening or loss of the levator muscle function, the eyes will be partially covered, just like the curtains lose the function of pulling and block the “window”, so serious The ptosis of the upper eyelid will affect the field of vision, and some people will use more force to raise the eye muscles in order to open the eyes normally, which will easily cause high and low eyebrows in the long run.


Divided according to degree, ptosis is divided into light, Moderate and severe:

mild ptosis, upper eyelid covering less than 1/3 of the cornea;

■ moderate ptosis, upper eyelid covers 1/3 to 1/2 of cornea;

severe ptosis, upper eyelid covers more than 1/2 of cornea;

severe ptosis, upper eyelid covers more than 1/2 of cornea;


02. What causes ptosis?

There are many causes of ptosis, mainly divided into congenital and acquired.

Congenital ptosis, that is, it has occurred since the child was born. Because the vision is blocked, it will affect the visual development, accompanied by amblyopia or strabismus.

Acquired ptosis, which is normal at birth, may be caused by traumatic, neurogenic, myogenic and mechanical reasons the day after tomorrow. Symptoms such as blurred vision, double vision, strabismus, and inflexible eye movement may appear.

03. Why do ptosis correction?

If ptosis is not treated in time, it may lead to eye diseases such as amblyopia and strabismus; if you look up for a long time, it will burden the spine, affect the health of the spine.

Currently, ptosis can be corrected by shortening the levator muscle, fascia suspension, and tarsal resection.

04. Is double eyelid surgery the same as ptosis surgery?

In fact, the two surgical theories are different. Ptosis is due to the weakening or loss of levator muscle function, while double eyelid surgery does not improve the strength of levator muscle ;

Ptosis surgery requires professional ophthalmologists to comprehensively evaluate the amount of levator muscle, eye position, size of palpebral fissure, frontalis muscle strength, etc., and then through the upper eyelid Levator muscle shortening, fascia suspension surgery, tarsal resection and other methods are used to correct the size of the eyes after surgery, and the overall appearance is beautiful. It is also a relatively complicated eye surgery.
