eye and orbital examination

It is usually examined by natural examination under natural light. When inspecting the eyeball, pay attention to its size, shape, presence or absence of protrusion or subsidence, and pay attention to the position of the eyeball, whether there is any involuntary nystagmus. More than 95% of tumors can be qualitatively diagnosed, but ultrasound shows poor bone tissue, so some tumors cannot show their size and whether they invade the bone wall. Therefore, it is necessary to combine other imaging examinations, such as CT and MRI, to make a comprehensive diagnosis.
