Treatment of intraocular melanoma of the ciliary body

The following are treatment options for all stages of the intraocular melanoma of the ciliary body. The types of treatments given are based on the unique needs of the person with cancer and the status of their vision.

Radiation therapy

Radiation therapy is one of the primary treatments for small- to medium-sized ciliary body melanomas. The types of radiation therapy that may be used are:

  • brachytherapy
  • proton beam radiation therapy


Surgery may be offered for a ciliary body melanoma. The type of surgery depends on the extent of the cancer and how much of the eye tissue needs to be removed. A local tumour resection may be an option for small melanomas of the ciliary body.

An enucleation may have to be done if there is no hope of regaining vision or the tumour:

  • is large
  • is causing increased pressure within the eye (secondary glaucoma)
  • has spread outside the eye

Active surveillance

Active surveillance may be an option for some people with a very small, slow-growing intraocular melanoma of the ciliary body. Treatment is given if the tumour begins to grow or if the tumour involves other structures in the eye.

Clinical trials

People with intraocular melanoma may be offered the opportunity to participate in clinical trials. For more information, go to clinical trials.
