1, physiological factors
With the increase of age, the skin tissue above the eyes will become more and more relaxed, and the eyelids will hang down quietly. This is a normal physiological phenomenon, everyone will experience such excessive aging.
2. Congenital factors lead to blepharoptosis
After birth, the eyes don't open, because the oculomotor nerve branch passes through the levator palpebralis muscle or oculomotor nerve nucleus, which leads to the lower edge of the upper eyelid covering the upper edge of the cornea excessively, thus making the eye fissure of the sick eye appear smaller than that of the normal eye. This kind of ptosis has certain heredity.
3. Small stroke
Sometimes, drooping eyelids may be a sign of minor stroke. If you feel numbness and fatigue in your face, hands and feet, or have a tingling sensation of acupuncture, you'd better see a doctor as soon as possible, because this symptom is a warning signal and must be dealt with immediately. The occurrence time of minor stroke is very short, ranging from 30 seconds to 24 hours, and the symptoms of 90% people last less than 2 hours. Patients with hypertension, high cholesterol and diabetes are at high risk. Therefore, when the eyelids droop, don't take it lightly.
4. Diabetes
If the elderly suddenly find one eyelid drooping, and often feel pain in the supraorbital region of the affected side, or see double images, they have not improved after injection of drugs, and accompanied by elevated blood sugar, it is likely that they have diabetes.
5, brain stem lesions
If one eyelid droops, the pupil is dilated, and the other upper and lower limbs are numb and weak, it may be a brain stem lesion. Children often have brain stem tumors, and the elderly are more common in brain stem angiopathy.
6, myasthenia gravis
If ptosis occurs slowly, the symptoms of both eyes are tandem, and it is light in the morning and heavy in the evening, and there is obvious fluctuation within one day, then it is very likely that you have myasthenia gravis.
7.intracranial aneurysm
Intracranial aneurysms can cause eyelid drooping, which is also unilateral. Suddenly, its pupils often dilate. If accompanied by severe headache, vomiting, convulsions, coma, etc. It is probably subarachnoid hemorrhage caused by ruptured aneurysm, which should be rescued by neurology department immediately.
8. Horner syndrome
If only one eyelid droops, the same side does not sweat under any circumstances. At this time, the pupil of the eye shrinks, the eyeball retreats and the iris changes color. At this time, it is likely to have Horner syndrome. The cause of this disease is severe facial nerve injury, which may be head and neck injury, brain tumor, spinal cord lesion and so on. , or lung cancer.
9. Systemic diseases
Unilateral blepharoptosis may also be caused by systemic diseases or ganglion diseases, such as tumors and infections, which need timely treatment.
10, Treatment of Pseudoptosis Correction
1, direct suspension of frontal muscle flap
Move the frontalis muscle flap made of frontalis muscle up and fix it with the upper eyelid plate, and directly lift the eyelid with frontalis muscle strength to correct ptosis. This method is suitable for congenital or pseudoptosis.
2. Frontal muscle lifting
Frontal muscle lifting is suitable for acquired or pseudoptosis. This method mainly uses various materials or tissues to connect the tarsal plate with the frontalis muscle, and indirectly uses the strength of frontalis muscle to correct ptosis.
3. Shorten levator palpebrae superioris muscle
It is only suitable for patients with mild or moderate loss of upper eyelid muscle function, and generally suitable for patients with false upper eyelid ptosis.
