Retinoblastoma - Commonest Eye Tumor in Children

Retinoblastoma - Commonest Eye Tumor in Children
This is the most common primary tumor of the eye in children. It arises from the retina. The retina is a layer of nerve tissue that coats the back of the eye, which is important for vision of person. Retinoblasts (immature cells of the retina) multiply during gestation and early life, to make enough cells to create the retina. As child grows, these cells mature & no longer differentiate. If these immature retinoblasts turn into cancer cells, retinoblastoma develops, the cause of which is unknown. The gene responsible is RB1 gene.
