For children with retinoblastoma, one way to destroy cancer cells is with cryotherapy. The Retinoblastoma team may decide this is a treatment your child should receive.

What Is Cryotherapy?

Cryotherapy is the use of extreme cold to freeze the cancer cells. This treatment is often done more than once. It can be used alone or in combination with laser therapy, chemo, and radiation therapy to destroy smaller tumors near the front part of the retina.

What Happens During This Procedure?

1. It is done in the operating room while your child is asleep. Your child will be given medicine to help them be asleep.
2. A very cold metal probe is put on the surface of the eye, next to the tumor. This freezes the cancer cells and destroys them.
3. The tumor is frozen and thawed many times during the procedure.
4. The probe is removed.

Care for Your Child After the Procedure

After the procedure, your child may have swelling, redness, and pain. This may last for 2 to 3 days. Pain medicine may be taken to help with any discomfort. A cold compress can also be placed over the eyelids. This may help your child feel better. Your child may also be given eye ointment to use. Use them as directed by your child’s provider.
