Retinoblastoma echocardiography or ultrasound

Overview
Retinoblastoma is a cancer of the retina. Development of this tumor is initiated by mutations that inactivate both copies of the RB1 gene, which codes for the retinoblastoma protein.

Ultrasound

 * Ultrasound: This is an painless test which uses sound waves to create a picture of the eye balls. Because tumors generate different echoes of sound waves than normal tissue, the doctor can locate a mass inside the body. Ultrasound is one of the most commonly used imaging tests to confirm retinoblastoma is present.
