The most common cause of orbital metastases in women is breast cancer, and in men, it is lung cancer. Treatment of these tumors, which may cause a drastic decrease in sharpness of sight, consists of laser photocoagulation, cryotherapy, chemotherapy, radiotherapy (RT), surgical resection and photodynamic therapy.
