Choroidal melanoma with tumor diameter less than 2cm and no diffusion phenomenon belongs to stage I tumor; Choroidal melanoma with tumor diameter of 2-5cm and no diffusion belongs to stage II tumor; If the tumor is larger than 2 cm in diameter and has local lymph node spread and metastasis, it is a stage III tumor; if the choroidal melanoma is large in size and has local and distal spread and metastasis, it is a stage IV tumor.
