Hello, my colleague's daughter is suffering from this rare condition retinoblastoma. Can anyone tell what causes retinoblastoma? What precautions should one take? What are the symptoms of such a condition? Thank you.

@zainn Retinoblastoma is a type of pediatric cancer that develops on the retina in the eye. The retina is located in the back of your eye. It has layers of cells that sense light and send information to your brain. Retinoblastoma treatments include cryotherapy, chemotherapy, radiation, and surgery. It is more common in children. A genetic mutation (a change in the child’s genes) causes retinoblastoma. The gene that causes retinoblastoma is called RB1. The mutation causes cells in the eye to grow uncontrollably, forming a tumor. Around 40% of the time, the child inherits the RB1 mutation from a parent (heritable retinoblastoma).
Symptoms of retinoblastoma are White pupils, Crossed eyes ( Eyes may appear misaligned, or one eye turns in a different direction than the other), Red or inflamed eyes.
It’s not possible to prevent nonheritable retinoblastoma. If you or your partner had retinoblastoma as a child, you have a 50% chance of passing the condition to your children Early diagnosis can significantly improve the prognosis.
