4-year-old boy’s eye tumor is divided into intraocular tumor and extraocular tumor, with different etiology and different treatment methods, and the general treatment methods include medication, surgery, radiotherapy and chemotherapy. 1. Drug treatment: if the tumor occurs in the eyelid and the blood vessels of the skin around the eyelid, it may be ocular hemangioma, which can be treated by injecting glucocorticoid drugs into the hemangioma. 2. Surgery: If dermatoid cysts appear in various parts around the eyes, they can be treated by surgery because they are common benign tumors. If the malignant tumor in the eye will cause the patient to have visual impairment, visual field defect, eyeball protrusion, and metastasis to the skull, surgery can be performed under the advice of the doctor. 3. Radiotherapy and chemotherapy treatment: in order to let the patient keep the eyeball and save the vision, radiotherapy and chemotherapy treatment can be used. Therefore, a 4-year-old boy with a tumor in his eye should consult a doctor in time to find out the cause of the disease, and the doctor will choose the appropriate treatment according to the patient’s condition.
