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

In intraocular retinoblastoma, cancer is found in one or both eyes and may be in the retina only or may also be in other parts of the eye such as the choroid, ciliary body, or part of the optic nerve. Cancer has not spread to tissues around the outside of the eye or to other parts of the body.
