Retinoblastoma is currently not treatable with hematopoietic stem cells, but it can be treated with radiotherapy, chemotherapy, surgery, and laser therapy. Retinoblastoma is the most common malignant tumor of the eye that occurs in children, which can affect their vision and even threaten their lives. Retinoblastoma should be treated as soon as it is detected. If it is detected at an early stage, laser treatment of the fundus can be considered, which can make the tumor shrink and atrophy. If the tumor is found to be relatively large and the opportunity for laser treatment is lost, radiotherapy and chemotherapy can also be considered to control the condition. If the tumor is already in an advanced stage at the time of discovery, surgical treatment, such as eye removal, will be required. It is recommended that patients with retinoblastoma should seek timely medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
