At this time, the swelling of the eyes will gradually improve with the development of the child.
It is generally believed that eyeball protrusion greater than 21mm, and the difference between the two sides of the eyeball protrusion is greater than 2mm, which is regarded as pathological eyeball protrusion. Causes of pathological eyeball protrusion include intraorbital tumor, vascular malformation, inflammation, hemorrhage and edema, as well as small orbital cavity volume, etc. Increased intraorbital pressure caused by any reason can drive the eyeball to protrude forward, which is manifested as eye swelling.
