Radioactive plaque

Depending on the location of the tumour, solitary tumours measuring between 6-12 mm, can be treated with a radioactive plaque. This is a tiny piece of radioactive material which is attached to the outside lining of the eye to kill off targeted cancerous cells inside.

If the child has treatment with a plaque, s/he will have to be nursed in a side room of their own for a few days, and close contact with other people will be limited because of the radioactive material used. Pregnant women and children are not allowed to visit during this period.

However, it is usually possible for parents to stay in the room with the child. The child will need to remain in this room between 1-3 days; the exact time depends on the strength of the plaque and the amount of radiation that is required for the particular tumour being treated.

The child will need to have a general anaesthetic so the plaque can be inserted and another one to remove the plaque.

In some cases, chemotherapy may be given to shrink the tumour prior to the application of a radioactive plaque.
