The nurse is assessing a 3-year-old suspected of having retinoblastoma. Which of the following is the most common finding in a child with retinoblastoma?

A white pupil

Explanation

•Retinoblastoma is a rare malignant tumor of the retina. It is usually diagnosed before the age of 5 and the cure rate is one of the highest among all childhood cancers.

•On examination, the child’s pupil appears white (red reflex is absent) or is described as a “cat’s eye."

Incorrect options:

•Strabismus occurs in only 20% of children with retinoblastoma, compared to the more common symptoms of the white pupil, seen in almost 60% of patients.

•Blurred vision and headache are not associated with retinoblastoma.
