MRI scan of the eye: This uses radio waves, a magnet, and a computer to make a series of detailed pictures.Ultrasound of the eye: This uses high-energy sound waves to make echoes, which make an image.electroretinography, which involves the use of small electrodes and light to study the retina.florescent angiography, a procedure that shows the blood vessels and flow of blood in the eye.ophthalmoscopy, which involves using a magnifying lens and light to view the retina and optic nerve.Eye exams with a dilated pupil: These tests involve widening the pupil to permit a view of the inside of the eye, including the retina.Physical exam: This entails looking for signs of illness, such as lumps or anything that appears unusual.Medical history: This includes checking for a family history of retinoblastoma.The diagnostic process includes the following: ­­­­­ crossed eyes or one eye that drifts in a different direction.The most common symptom is a white pupil. Symptoms of children’s eye cancer (retinoblastoma) Also, it does not increase cancer risk in other parts of the body. The mutated gene is in one cell of one eye, which results in the development of only one tumor in one eye. This type affects two out of three children with retinoblastoma. Additionally, since the gene mutation is in every cell, they are more likely to develop cancer in other parts of the body. Typically, children with the RB1 gene mutation have retinoblastoma in both eyes, and they frequently have several eye tumors. Only a small percentage of children with this gene inherit it from a parent. Instead, they develop it while in the womb. The abnormal RB1 gene is in every cell of the body, including those of the retina.Īlthough this is heritable, most children have no family history of the cancer. An abnormality in the RB1 gene is congenital, which means a person has it at birth. It stems from a mutation of the RB1 gene.

This type affects 1 in 3 children with retinoblastoma. Details are below: Heritable, or congenital Retinoblastoma may be heritable or nonheritable.
