Retinoblastoma is a malignancy of the retinal cell layer of the eye. It is the most common eye tumor in children, it accounts for about 3% of the cancers occurring in children and the age of diagnosis is 0-4 years.
It can occur in one eye (unilateral) or in both eyes (bilateral). Retinoblastoma is usually confined to the eye and does not spread to other tissues.
In about 40% of the cases, retinoblastoma is hereditary, or germline. Most cases present with leukocoria, which is occasionally first noticed after a flash photograph is taken. Strabismus is the second most common presenting sign and usually correlates with macular involvement. Change in iris color is another symptom, the iris (colored part of the eye) can change color in one eye, sometimes only in one area.
With improvements in the diagnosis and management of retinoblastoma over the past several decades, metastatic retinoblastoma is observed less frequently.
The present challenge for the Instituto de Oncología Intervencionista (Interventionist Oncology Institute) and for those others who treat retinoblastoma is to prevent blindness and other effects of treatment that reduce the life span or the quality of life after treatment.
If you see one or more of the signs of retinoblastoma, IDOI MEXICO recommends you to get your child’s eyes checked urgently just to be safe.
