Sponsored by: National Center for Research Resources (NCRR) Information provided by: National Center for Research Resources (NCRR) ClinicalTrials.gov Identifier: Purpose Hearing loss and loss of vision can be very harmful to the well-being and life of people who suffer from them. Usher syndrome is the name of a disease where people have both hearing loss and visual loss. In fact more than half of people who are deaf and blind have Usher syndrome. In this study we are trying to find the causes of all types of Usher syndrome and to learn more about how the eyes and ears work. Usher syndrome is caused by changes in our genes that lead to mistakes in the functioning of our eyes and ears. We may conduct hearing tests called audiograms to test hearing and a vision test called an electroretinogram (ERG) to test how well the retina (the part of your eye that senses light) is working on participants in the study. From these tests we can tell what kind of Usher syndrome a participant may have. We will then get DNA from participants by drawing blood. The DNA will be studied, along with DNA from members of the participant's family and other families, to try to find the gene that is causing Usher syndrome in the participant.

Verified by National Institutes of Health Clinical Center (CC) February 18, 2005 Sponsored by: National Eye Institute (NEI) Information provided by: National Institutes of Health Clinical Center (CC) ClinicalTrials.gov Identifier: Purpose This study will explore clinical and genetic aspects of Usher syndrome, an inherited disease causing deafness or impaired hearing, visual problems, and, in some cases, unsteadiness or balance problems. Patients with type 1 Usher syndrome usually are deaf from birth and have speech and balance problems. Patients with type 2 disease generally are hearing impaired but have no balance problems. Patients with type 3 disease have progressive hearing loss and balance problems. All patients develop retinitis pigmentosa, an eye disease that causes poor night vision and eventually, blindness. Patients of any age with Usher syndrome may be eligible for this study. Patients who have had eye and hearing evaluations are asked to send their medical records to the research team at the National Eye Institute (NEI) for review. They are also asked to have a blood sample drawn by a medical professional and sent to NEI for genetic analysis. Finally, they are interviewed about their family histories, particularly about other relative with eye disease. Patients who have not been evaluated previously have the following tests and procedures at NIH:

Usher syndrome is an inherited condition that causes a serious hearing loss that is usually present at birth or shortly thereafter and progressive vision loss caused by retinitis pigmentosa (RP). Retinitis pigmentosa is a group of inherited diseases that cause night-blindness and side vision loss through the progressive degeneration of the retina, the light-sensitive tissue at the back of the eye that is crucial for vision. Some people with Usher Syndrome experience problems with balance. Symptoms of Usher Syndrome? The symptoms and signs of Usher syndrome depend on the type. Some common symptoms are: Hearing loss leading to deafness Loss of vision leading to blindness Balance problems Speech difficulties Types of Usher Syndrome? Researchers have described three types of Usher syndrome-type I, type II and type III. Individuals with Usher syndrome type I are nearly or completely deaf and experience problems with balance from a young age. They usually begin to exhibit signs of RP in early adolescence.

What is Usher Syndrome? Usher Syndrome (UH-shur SIN-drum) is a disease that makes people lose some of their hearing and some of their vision. The vision loss is caused by a disease called Retinitis Pigmentosa . Doctors call this disease RP for short. People with Usher Syndrome are usually born with some hearing loss. The amount of hearing loss is different for different people: It can be mild, moderate, severe, or profound. It can get worse over time. This is called progressive hearing loss . Or the hearing loss can stay the same. People with Usher Syndrome usually lose their sight later in life. People with Usher Syndrome lose their night vision first. That means they have trouble seeing in the dark. It usually starts to happen when the person is a teenager. But it can also happen earlier, during childhood. Not everyone loses the same amount of seeing and hearing People with Usher Syndrome usually don't lose all of their hearing and sight. But they usually have lost a lot of their sight by the age of 30 or 40. This kind of sight loss is called being

The hearing loss is usually congenital and may be total or partial. Retinitis pigmentosa, a progressive deterioration of the retina which causes night blindness, tunnel vision and finally severely reduced central vision, may not occur until late childhood or early adulthood. In some forms poor balance is an associated problem. Diagnosis of Usher syndrome may be delayed until the visual problems have become significant because peripheral and night vision are not routinely tested in school children. There are three types of the syndrome. Type I is characterised by profound congenital hearing loss, poor balance and retinitis pigmentosa before the age of 10. Type II presents moderate to severe hearing loss, normal balance and retinitis pigmentosa develops in the late teens or early 20's. Type III is characterised by progressive hearing loss and Retinitis Pigmentosa progressing at a variable rate, generally with onset around the second or third decade of life.

About Services Awareness The Link ... Contact Us Brief information for parents on vision and hearing impairment and Usher Syndrome Victorian-based services. DOES YOUR CHILD HAVE? This information is designed to alert parents to changes in their children's hearing and vision. It provides details on the relevant organisations to contact for further information. This information has been developed by the Victorian Usher Syndrome Project Committee (1998) VISION IMPAIRMENT Poor vision is not always apparent with children. Children themselves are not always aware that they see worse than other people - the child believes that everyone sees the way he/she does. Children may suffer from one of the frequent vision impairments such as short-sightedness, cross-eye astigmatism, etc. In most cases, these vision impairments can be easily corrected. Symptoms in children alerting you to vision impairment include: * Writing above or below lines * Often blinking or rubbing eyes * Wrinkling or squinting eyes to look at something closely * Hold small objects close to examine them * Sitting close to TV * Difficulty estimating distances * Fear of stumbling * Avoiding games which require quick visual reaction (e.g. skipping, ball games)

Skip navigation Viewing Options Sign In Search this site Home About deafblindness About Sense Publications ... General factsheets About Usher syndrome About Usher syndrome Factsheet two - About Usher Syndrome Usher syndrome is one of the most challenging disabilities that anyone can face. People with Usher are born deaf or hard of hearing, then gradually start to lose their sight in late childhood. But despite the enormous challenges this brings, people with Usher can achieve a great deal. With the right support, many people can go to college, get jobs, find a partner, and enjoy their leisure, just like anyone else. What is Usher syndrome? Usher syndrome is a genetic condition which causes profound deafness or partial hearing from birth, and sight loss over a number of years. This sight loss often begins in late childhood and is caused by an eye condition known as Retinitis Pigmentosa (sometimes called RP). Usher is also a significant cause of deafblindness in adults. Deafness People who have Usher syndrome experience moderate to profound deafness. Children born profoundly deaf have average losses of 95 db and over, which means that they cannot hear continuous speech sounds, even with a powerful hearing aid. Profoundly deaf children tend to prefer sign language as their natural language, although some do develop speech. Many sign language users feel very much part of the deaf community and culture.
