Retinoblastoma Treatment

1. What is Retinoblastoma?

Retinoblastoma is a cancer that develops in the retina, the light-sensitive tissue at the back of the eye.

It may affect:

• One eye (unilateral retinoblastoma)
• Both eyes (bilateral retinoblastoma)

Treatment priorities generally focus first on saving the child's life, followed by preserving the eye and vision whenever medically possible.

2. What Are the Common Signs and Symptoms?

Possible signs may include:

• White reflection or glow in the pupil (leukocoria)
• Squinting or misaligned eyes
• Redness or swelling of the eye
• Reduced vision
• Eye pain in advanced cases
• Enlargement of the eye in some cases

A child with suspected retinoblastoma requires urgent assessment by an experienced ocular oncology specialist.

3. How Is Retinoblastoma Diagnosed?

Evaluation may include:

• Specialist eye examination
• Examination under anaesthesia (EUA) where required
• Ocular ultrasound
• MRI of the eye and brain
• Assessment of both eyes
• Genetic evaluation in selected patients
• Additional staging investigations where appropriate

Biopsy is generally avoided in typical intraocular retinoblastoma because of the potential risk of tumour spread.

4. What Treatment Options Are Available?

Treatment depends on the size, location and extent of the tumour and whether one or both eyes are affected.

Options may include:

• Systemic chemotherapy
• Intra-arterial chemotherapy in selected patients
• Intravitreal chemotherapy for selected disease
• Laser treatment (photocoagulation)
• Cryotherapy
• Plaque brachytherapy in selected cases
• External beam radiation therapy in selected situations
• Enucleation (removal of the affected eye) when necessary
• Treatment for advanced or extraocular disease where required

Treatment is planned by a specialised multidisciplinary team.

5. What Does the Treatment Process Involve?

The general treatment pathway includes:

Specialist ocular examination → MRI and diagnostic assessment → Evaluation of both eyes → Disease classification → Multidisciplinary treatment planning → Personalised treatment → Regular eye examinations and imaging → Response assessment → Long-term follow-up

Repeated examinations under anaesthesia may be required during treatment and surveillance, particularly in young children.

6. How Long Does Retinoblastoma Treatment Take?

The duration depends on the extent of disease and treatment approach.

Typical considerations include:

• Initial evaluation: may require several days
• Chemotherapy: may be given over multiple treatment cycles
• Local eye treatments: may require repeated sessions
• Follow-up examinations: required regularly for several years
• Long-term surveillance: important, particularly for children with hereditary retinoblastoma

The treating team provides an individual treatment and follow-up schedule.

7. What Are the Expected Outcomes?

When diagnosed and treated appropriately, retinoblastoma can often be successfully controlled.

Treatment aims may include:

• Saving the child's life
• Controlling the cancer
• Preserving the eye where possible
• Preserving useful vision where possible
• Reducing the risk of recurrence or spread
• Providing long-term surveillance

Outcomes depend on the stage, whether disease is limited to the eye, involvement of one or both eyes and response to treatment.

8. What Are the Risks or Considerations?

Risks and considerations depend on the treatment used and may include:

• Temporary or permanent reduction in vision
• Effects of chemotherapy
• Eye inflammation or damage from local treatment
• Risk of tumour recurrence
• Need for removal of an eye in advanced cases
• Long-term monitoring for hereditary forms of retinoblastoma
• Risk of additional cancers in some patients with hereditary retinoblastoma

The treatment team discusses the expected benefits and risks for the individual child.
