Retinoblastoma is a common intraocular malignancy in childhood and can be life-threatening when detected at an advanced stage. Therefore, many parents who learn that their child has retinoblastoma often go through a painful process from not accepting it at first to actively seeking a solution later. There is no doubt that the main treatment for retinoblastoma nowadays is chemotherapy, but chemotherapy is also only a kind of volume reduction treatment, which means that the volume of the tumor is reduced, and then treatments such as condensation and photocoagulation are used to eventually destroy the tumor. In China, due to the lack of early screening, not many retinoblastomas are detected at an early stage, and many of these patients are already at an advanced stage when they are detected, and chemotherapy is the treatment of choice. In fact, for smaller tumors, many can begin treatment with condensation and photocoagulation and obtain good results. For pediatric ophthalmologists experienced in treating fundus diseases, laser photocoagulation of retinoblastoma is not complicated, and the younger the child, the simpler the photocoagulation treatment.
