About Retinoblastoma in Children

Retinoblastoma, which occurs most commonly in children under the age of 5 years old, is a malignant (cancerous) tumor that grows in the retina — the light-sensing part of the eye that sends the images we see to the brain. Children who develop retinoblastoma are often diagnosed before 2 years old. A child’s age at diagnosis often correlates with laterality (that is, whether the disease is found in one or both eyes). For example, children with retinoblastoma in both eyes often are diagnosed within the first 12 months of life.

Retinoblastoma is the most common eye cancer in children, accounting for about 3 percent of cancers in kids younger than 15 years old. Retinoblastoma in children rarely metastasizes (spreads) beyond the eyeball, but it can metastasize to the brain, spine, blood, soft tissues and bone marrow.

Our renowned oncologists, hematologists and researchers at the Nemours Center for Cancer and Blood Disorders, a Children’s Oncology Group (COG) member institution, work together with top Nemours ophthalmologists (who are pioneers in detecting ophthalmologic disorders in utero, or still in the womb) to diagnose and provide retinoblastoma treatment in children, kids have excellent outcomes.

Types of Retinoblastoma We Treat

At Nemours, we offer retinoblastoma treatment for children of all ages, from newborns to adolescents. Types of retinoblastoma we treat include: 

Hereditary Retinoblastoma

Hereditary (present at birth) retinoblastoma is caused by a genetic change (called a “germline mutation”) in the Rb1 gene that’s inherited from an affected parent or may have occurred at the time of conception; and a second genetic mutation that occurs while the baby develops in the womb. Hereditary retinoblastoma may present as tumors in both eyes, multiple tumors in one eye, or a family history of retinoblastoma. Genetic testing is performed to further identify hereditary retinoblastoma.

Sporadic Retinoblastoma (Nonheritable Retinoblastoma)

Also known as “unilateral retinoblastoma” (because it occurs mainly in one eye), sporadic retinoblastoma represents 70 to 75 percent of all retinoblastoma cases. This type is caused by simultaneous genetic changes in the Rb1 gene that occur randomly (by chance) during retinal development. Only the tumor contains these genetic mutations — the rest of the body has normal Rb1 genes.

Diagnosing Retinoblastoma in Children

Signs & Symptoms of Retinoblastoma

  • pupil leukocoria (white or yellowish area in the dark part of the eye seen in light or, commonly, in flash photography)
  • poorly aligned (“wandering”) eyes
  • vision problems
  • eye pain 

Testing & Evaluations

If your child possibly has retinoblastoma, we work together to appropriately diagnose and stage the disease through a variety of tests and procedures, including:

  • thorough eye examination, physical examination and medical history
  • blood tests 
  • medical imaging (typically with MRI and/or ultrasound)
If there is concern the cancer has spread, you doctor may recommend additional tests, such as:
  • lumbar puncture
  • bone marrow biopsy and aspiration

Treating & Caring for Children With Retinoblastoma

Your Child's Comprehensive Retinoblastoma Care Team

If we discover retinoblastoma, our multidisciplinary (collaborative) team plans the most effective treatment personalized to your child’s needs. In addition to an experienced, compassionate cancer coordinator (a nurse who provides your child and family support, education and care coordination), Nemours’ pediatric eye cancer teams include: 

  • oncologists (cancer specialists)
  • hematologists (specialists in blood disorders)
  • ophthalmologists (eye specialists)
  • ocular oncologists (ophthalmologists who specialize in eye cancer)
  • surgeons (general and ophthalmologic surgeons)
  • pathologists (diagnose diseases by examining body tissues, fluids and organs)
  • geneticists (perform genetic counseling and testing)
  • radiologists (diagnose diseases through medical imaging)
  • radiation oncologists (specialists in radiation therapy treatment)
  • interventional radiologists (perform image-guided minimally-invasive procedures)
  • behavioral health specialists (psychologists and psychiatrists)
  • registered dieticians (nutrition specialists)
  • oncology nurses (registered nurses specializing in cancer)  

Your care team is here to provide your family with ongoing support and follow-up. We always include you in the entire process, because we truly believe in the healing power of families, and that you know your child best.

Innovative Pediatric Retinoblastoma Treatment at Nemours

Retinoblastoma treatment depends on a child’s age, overall health, extent of the disease and other factors. Nemours offers advanced and innovative childhood cancer treatments and approaches (called “modalities”) that aren’t available at other children’s hospitals.

We may use one or a combination of modalities that include:
  • chemotherapy — Tumor-killing medications are given orally, through injection or intravenously (in a vein).
  • external beam radiation — Beams of radiation are carefully focused onto the tumor to kill cancer cells.
  • brachytherapy — Radioactive material (little rods or pellets) is placed within the tumor to deliver beams of radiation to specific areas. This form of treatment minimizes the damage to surrounding healthy tissue.
  • radioactive plaques — A disk is implanted in the eye with a dose of radiation applied directly to the tumor site.
  • cryotherapy — Liquid nitrogen or argon gases (two extremely cold substances) are used to freeze and destroy diseased tissue.
  • transpupillary thermotherapy — Laser energy (through the use of infrared light) heats up cancer cells and surrounding blood vessels, which kills the cells.
  • photocoagulation — Laser energy is delivered to blood vessels surrounding the tumor, causing blood clots and depriving the cancer cells of nutrients.
  • enucleation — In severe cases of retinoblastoma, the entire eyeball is removed to prevent the spread of cancerous cells to other areas of the body.
Via our partners at Thomas Jefferson University Hospital and Wills Eye Hospital, we also offer:
  • intra-arterial chemotherapy (selective injection of chemotherapy drugs into the blood vessel that feeds the eye to treat tumors within the eye )
For your child’s overall health and wellness, we also prescribe:
