Orbital tumor, due to its special location, no matter benign or malignant, will bring great influence to the patient’s appearance and vision, and malignant tumor is even a direct threat to life. Impact on appearance The volume of orbital tumor, which is the “home” of the eyeball, is limited. When orbital tumor occurs, it will continuously occupy the territory that belongs to the eyeball. When the tumor is small, no abnormality can be seen in appearance, but with the gradual growth of the tumor, the eyeball will be pushed outward, and the appearance will show that the eyeball is protruding and shifting, and the eyelid can not be lifted up, which will bring great trouble to the patients. Impairment of function Compared with the appearance, the more serious impact is the impairment of the function of the eyes. Some orbital tumors are relatively large or particularly deep, which will compress the optic nerve and cause vision loss or even blindness. Others compress the motor nerve and sensory nerve of the orbit, causing eye movement disorder, strabismus, pain and so on. 3.Threatening life Some orbital tumors are malignant, which will invade to the neighboring tissues such as brain and sinus, and also metastasize to lungs, liver, bones and other distant organs, which will bring threat to the patient’s life. When it is cut off, it is not a good idea to suffer. When an orbital tumor is found, no matter how benign or malignant it is, it is better to treat it as soon as possible.
