What Is Usher Syndrome?
3. Type 2 Usher syndrome
In comparison to type 1, type 2 cases are less severe. The children are born with moderate to severe hearing loss. They are often able to communicate orally and retain normal balance. Depending on the degree of hearing impairment, these children can often benefit from using hearing aids or cochlear implants.
Vision problems tend to develop when children reach adolescence. This begins with night blindness that progresses slowly. The deterioration does not however reach total blindness. Because of this delay in the presentation of the second symptom of vision loss, most do not learn they are suffering from Usher syndrome until they are in their teens.
