Pediatric Retinoblastoma
Retinoblastoma, the most common type of eye tumor seen in children, occurs most often in young children before the age of five and affects boys and girls in equal numbers. The tumor may be in one eye (referred to as unilateral retinoblastoma), or in both eyes (bilateral retinoblastoma).
Retinoblastoma tumors originate in the retina, the light-sensitive layer of the eye which enables the eye to see. About 75 percent of retinoblastoma cases are unilateral, and 90 percent of retinoblastoma patients have no family history of the disease.
Retinoblastoma occurs most often before the age of five. There are approximately 350 new diagnosed cases per year in the United States, making it the seventh most common pediatric cancer. Retinoblastoma affects one in every 15,000 to 30,000 live babies born in the United States and is found in boys and girls from all backgrounds.
More than 95 percent of children treated for retinoblastoma in the US are cured. In addition, more than 90 percent of patients retain at least one eye and more than 80 percent of children treated keep 20/20 vision.
