With the widespread application of electronic products and the reduction of outdoor activities,
myopia has also become a major problem that threatens the health of Chinese people, and the number of people with high myopia has gradually increased.
According to the commonly used classification standard for myopia, degree>600 degrees can be regarded as high myopia, but this standard is actually simple and crude, and does not take into account the influence of astigmatism. The presence or absence of lesions in the fundus was not considered.
Most people have axial myopia. The higher the degree of myopia, the longer the eyeball will be “pulled”, and the greater the possibility of fundus lesions.
However, some people have less than 600 degrees of myopia and may have obvious fundus lesions.
The fundus lesions caused by high myopia are actually irreversible
High myopia has many risks of eye diseases, such as retinal detachment, retinal tears, floaters, glaucoma, cataract, fundus hemorrhage, macular degeneration, etc.
Therefore, the higher the degree of myopia, the greater the risk of blindness, especially under the impact of external force, or playing some severe stimulation projects, it is easy to cause retinal detachment.
Friends with high myopia must have a fundus examination every year< /p>
Usually speaking, the axial length of normal adults is usually about 24mm, while for those with high myopia of more than 600 degrees, the axial length of the eye is at least about 26mm or more, which is more than 2mm longer than those without myopia.
If you think of a normal eyeball as a balloon, a highly myopic eyeball is like a balloon that has been blown up and elongated, and the wall of the ball will become thinner, as will the sclera, choroid, and retina of the eyeball.
If the problem of proptosis is not treated in time, it may endanger the patient’s life, and behaviors such as bowing the head or exhaling forcefully in daily life will cause the eyeball to turn out.
An important feature of proptosis is temporary proptosis, the degree of proptosis can increase or decrease with head position, vary in duration, and occur frequently or occasionally .
When does temporary ectropion occur?
Temporary ectropion occurs when the patient lowers their head, exhales forcefully, compresses the jugular vein, or twists the neck to one side. In addition, temporary ocular trauma can also be accompanied by symptoms such as ptosis, swelling of the eyelid, and increased intraocular pressure.
What is the main cause of exophthalmos in patients?
1. Eye trauma
If the patient has intraorbital hemorrhage, retro-orbital hemorrhage, orbital contusion, crush syndrome and other symptoms.
2. Ocular inflammation
Thyroid-related fundus diseases and inflammatory pseudotumors may lead to exophthalmos.
3. Eyeball infection
Orbital cellulitis, orbital subperiosteal abscess, acute sinusitis.
4. Eye tumors
Butterfly cyst, capillary hemangioma, rhabdomyosarcoma, metastatic cancer, etc.
5. Nerve Palsy
Both cranial nerve palsies and ophthalmoplegia can cause proptosis.
In addition, some patients’ exophthalmos are caused by congenital malformations. For example, patients with hydrocephalus may cause their own exophthalmos.
To prevent and treat exophthalmos, first understand the causes of exophthalmos
There are many reasons for protruding eyes. Generally, patients with different reasons should take different treatment methods.
However, there is a general principle of treatment, that is, patients should go to an eye hospital in time once they have suspected symptoms of exophthalmos and receive appropriate treatment according to the type.
At the time of treatment, attention should be paid to eye trauma caused by trauma, which should be checked and treated in time. If not treated in time, the eyeball will further protrude and the eyelid will not close completely, which can easily lead to exposure keratitis and damage vision.
If the bulging eye is caused by a malignant tumor, it can even be life-threatening if left untreated. Therefore, to prevent protuberance of the eyes, attention should be paid to physical examination, early detection of tumors, and prevention of trauma.
What are the early symptoms of proptosis?
The early symptoms of exophthalmos were mostly non-specific, including foreign body sensation, redness, lacrimation, photophobia, morning eyelid edema, and decreased blinking.
The late external canthus persists and the external rotation is limited, which may lead to symptoms such as diplopia, decreased visual acuity, swelling of the eyeball, and increased intraocular pressure.
Once the above symptoms appear, it is recommended that patients should seek medical treatment in time to minimize the adverse effects caused by exophthalmos.
Before examining the symptoms of exophthalmos, the doctor will first understand the onset time and symptoms of the patient, and whether there are other eye diseases, and whether the patient has diseases such as hyperthyroidism, tumor or trauma, and the patient needs to cooperate with the doctor carefully for treatment.
