The neonatal hearing screening, also called algo screening or OAE screening, is a hearing test for new-born babies. All children born in the Netherlands are eligible to this test.
A child that appears to have any trouble hearing is referred to the Audiological Centre for further hearing tests. Usually a consult with an ENT specialist is included as well.
The physician discusses the possibility of a DNA test to find the cause of the deafness. After approval of a DNA test, the child will be referred to the antropogenetic department. The clinical geneticist will, if necessary in cooperation with the ENT specialist, discuss the outcome of the DNA test with the parents.
If no tests in connection with hereditary deafness were done in the past, it often is the ophthalmologist who makes the diagnosis for Usher Syndrome as soon as the first eye problems occur. The ophthalmologist can quite easily see any deviations of the retina by means of a slit lamp and advise to do further tests. The outcomes of these tests combined with the loss of hearing may lead to the diagnosis for Usher Syndrome. The outcome of a DNA tests can confirm the diagnosis.
