Exophthalmos, also known as exophthalmos, refers to an abnormal state in which the eyeball moves forward and protrudes. The normal position of eyeball in orbit is that the top of cornea does not exceed the upper and lower edges of orbit. The difference of binocular protrusion is generally less than 2mm, otherwise pathological exophthalmos should be considered. Exophthalmos caused by various reasons will lead to ugly face and appearance. Therefore, in order to find a correction method, eyeball correction can correct exophthalmos. Exophthalmos refers to exophthalmos beyond the normal range, which can be a sign of eye diseases or a symptom of systemic diseases. If there is unilateral or bilateral protrusion, you should go to the hospital as soon as possible when there is exophthalmos. Exophthalmos can make people feel unattractive, and severe exophthalmos can also give people a feeling of fear. Corrective surgery for exophthalmos can solve this situation. Cause of exophthalmos: 1. Sudden unilateral exophthalmos is often caused by bleeding or inflammation of orbit or sinus. 2. Pulsating tumors in internal carotid artery and cavernous sinus can lead to pulsating exophthalmos with murmur. 3. Unilateral high myopia or meningioma can cause unilateral exophthalmos. Exophthalmos are also true and false. Pseudoexophthalmos is usually caused by diseases of eyeball itself, such as corneal staphyloma, axial high myopia, congenital glaucoma and so on. From the etiology, true exophthalmos can be divided into inflammatory, endocrine, vascular, neoplastic, traumatic and rare parasitic. The treatment of exophthalmos depends on the etiology. The common carotid artery should be ligated in the treatment of pulse tumor. Correction method of exophthalmos: 1. Enlarge the orbital capacity: destroy the bone debris around the orbit, make the adipose tissue around the eyeball overflow into the hole, thus making the eyeball shrink back. This surgical method is suitable for cases with severe exophthalmos. 2. Methods of reducing orbital contents: Mainly suitable for patients with less serious exophthalmos. The surgical method is to reduce the fat in the deep orbit as much as possible while remodeling the upper eyelid or lower pouch, so as to increase the space for the eyeball to move freely in the orbit and naturally retract inward.
