Treatment of diseases: orbital non-Hodgkin's malignant lymphoma Indication 1, a wide range of primary malignant tumors in the orbit, radiotherapy is not sensitive, simple tumor resection is difficult to complete; 2. Although a wide range of intraorbital metastatic malignant tumors or intraorbital malignant tumors have distant metastasis, eye pain is severe, radiotherapy and chemotherapy are ineffective; or benign tumors are covered with eyelids, and the eyeballs have been destroyed and highly prominent.
