About Usher Syndrome
Usher syndrome is the leading cause of hereditary deaf-blindness in the world. Approximately 400,000 people worldwide are affected by this genetic disorder. Children with Usher syndrome are born with or develop hearing loss and the vestibular system can be affected too, which adversely affects their balance. Early in life, they will experience symptoms of a progressive vision disorder known as Retinitis pigmentosa (RP). Initially, they will develop night blindness, followed by a narrowing of the visual field, commonly known as “tunnel vision.” Symptoms and disease progression vary from person to person. Most individuals with Usher syndrome are legally blind by the time they are young adults.
There is currently no treatment for Usher syndrome. However, there are a number of treatments in or close to clinical trials, which will potentially help people with Usher syndrome.
