Retinoblastoma is a rare childhood eye cancer that arises from the retina. It is seen most often in young children and many cases are diagnosed before 2 years of age. It may affect one eye or both eyes. Early diagnosis is crucial not only for survival, but also for maximizing the chance of preserving the eye and useful vision. ^[1][3]

For many families, the first clue is a white reflection in the pupil seen in flash photography. Other signs may include strabismus, persistent eye redness, swelling, or suspected vision loss. ^[1][2]

What are the symptoms?

A white color in the pupil reflex, eye redness, swelling, strabismus, and vision problems are among the main signs. The white reflex may not appear in every photograph, which is why repeated episodes should not be dismissed just because it is inconsistent. ^[1]

What causes it and can it be hereditary?

Retinoblastoma develops because of genetic changes affecting how retinal cells grow and die. Some cases are hereditary and some are sporadic. Hereditary forms are more likely to involve both eyes and may require family evaluation as well as genetic counseling. ^[1][3]

How is it diagnosed?

Diagnosis begins with specialist pediatric eye evaluation. Detailed fundus examination is often performed under sedation or anesthesia in young children. Imaging helps determine the size and location of the tumor and whether there is spread beyond the eye. ^[2][3]

What are the treatment options?

Treatment depends on tumor size, extent, and whether vision and the eye can realistically be preserved. Chemotherapy, local therapies such as cryotherapy, thermotherapy, laser-based treatment, radiation therapy, and in selected cases removal of the eye (enucleation) may all be considered. ^[2][3]

When should you seek medical care?

A white glow in the pupil on photographs, new strabismus, unexplained eye redness or swelling, or concern that a child is not seeing well all justify prompt evaluation. ^[1][2]

FAQ

At what age is retinoblastoma most common?

It is most common in young children, and many cases are diagnosed before age 2. ^[1]

What does a white glow in the eye on photos mean?

It can be a sign of retinoblastoma or another eye disorder. It does not always mean cancer, but it requires evaluation. ^[1][2]

Can retinoblastoma be hereditary?

Yes. Some cases are linked to hereditary genetic changes, and this can increase the chance of disease in both eyes. ^[1][3]

Does every child need eye removal?

No. Many children can be treated with eye-preserving therapies such as chemotherapy and local treatments. ^[2][3]

Why is follow-up important after treatment?

Because recurrence, new lesions, vision outcomes, and hereditary risk-related issues may require long-term monitoring. ^[1][3]
