Disease analysis: exophthalmos, also known as exophthalmos, refers to the abnormal state that 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. The causes of pathological exophthalmos are all diseases with increased orbital contents or all extraocular muscles are in a state of relaxation or paralysis. Suggestion: According to the different nature and occurrence process of exophthalmos, there are two main correction schemes: 1, expanding the orbital capacity: destroying the bone debris around the orbit, allowing the fat tissue around the eyeball to overflow into the hole, thus retracting the eyeball. This surgical method is suitable for cases with severe exophthalmos. 2. Method of reducing orbital contents: Mainly for patients with less prominent eyeball, the surgical method is to reduce the fat in the deep orbit as much as possible while reshaping the upper eyelid or lower pouch, thus increasing the space in the orbit, allowing the eyeball to move freely, and the eyeball will naturally retract inward.
