Treating Retinoblastoma TOPICS

Laser therapy (photocoagulation) for retinoblastoma

Photocoagulation is a type of treatment that uses a laser beam aimed through the pupil. The laser is focused on the blood vessels that surround and supply the tumor, destroying them with the heat caused by the beam. Photocoagulation is effective only for smaller tumors toward the back of the eye.

Your child will be under general anesthesia (in a deep sleep) during the treatment. The treatment is usually given 2 or 3 times, with about a month between treatments.

Possible side effects: In some cases, laser therapy can damage the retina, which can lead to blind spots or temporarily cause the retina to detach from the back of the eyeball.
