IPhone Flash Helped Identify Retinoblastoma Josie Rock was taking pictures of her 3-month-old son Asher when the lighting in the room suddenly dimmed, initiating the flash on her iPhone. Asher's eyes opened wide, but instead of his pupils glowing red, as they normally do when a flash is used, one of his pupils was white. "His right eye glowed goldish-white, and his left eye was the regular red," said Josie, a labor and delivery nurse who resides in Gainesville, Georgia. "I kept taking more pictures, and they were all the same." Josie pulled out a professional camera and attached a flash to make sure that what she was seeing was real and not just an artifact caused by the iPhone camera. The result was the same. A visit to Asher's pediatrician a few weeks later and then one to a pediatric ophthalmologist confirmed her worst fears — her son had retinoblastoma. Fortunately, Josie had learned about the "white glow" in a lecture only a few months before Asher was born. When the ophthalmologist dilated Asher's eyes, the tumor was visible. Although the tumor was large, it had not yet affected the optic nerve, explained his mother.
