    • Crossed eyes
    • Double vision
    • Eyes that do not align
    • Eye pain and redness
    • Poor vision
    • Differing iris colors in each eye

    If the cancer has spread, bone pain and other symptoms may occur.

    • Eye exam with dilation of the pupil
    • CT scan or MRI of the head
    • Ultrasound of the eye ( head and eye echoencephalogram)
    • Bone marrow biopsy and cerebrospinal fluid examination in the case of more aggressive tumors
