All newborn babies are screened for hearing problems. If a hearing problem is found in the newborn, the baby will have follow-up testing. Your child's healthcare provider will test hearing, eyesight, and balance to diagnose Usher syndrome. The tests include:
Electronystagmography (ENG). This test checks eye movements to help diagnose balance problems.
Vision testing. Different tests are used to test the eyesight of very young children.
Eye exam. An eye doctor will look at the retina during an eye exam.
Electroretinography (ERG). This test checks how the retina reacts to light. It is used to diagnose retinitis pigmentosa.
Hearing evaluation. A hearing specialist will examine the ears and do a series of tests to check your child’s hearing.
One a child is diagnosed, he or she may have genetic testing to find out the type of Usher syndrome.
