Pediatricians at Norton Children’s Medical Associates practices are using customized iPhones to detect serious eye problems, including amblyopia – lazy eye – and some types of eye cancer, such as retinoblastoma, in children age 6 and younger. “Detecting these issues in young kids has always been tough, because children don’t want to stay still and can’t communicate vision problems,” said April R. Mattingly, M.D., pediatrician at Norton Children’s Medical Associates – Crestwood. “Some of these issues keep kids from seeing well in the classroom, but others can lead to surgery or vision loss if not caught early enough.”
