Context: Stages of Retinoblastoma / Treatment for retinoblastoma depends on whether it is intraocular (within the eye) or extraocular (outside the eye).

In extraocular retinoblastoma, cancer has spread beyond the eye. It may be found in tissues around the eye (orbital retinoblastoma), or it may have spread to the central nervous system (brain and spinal cord) or to other parts of the body such as the liver, bone, bone marrow, or lymph nodes.
