Overlapping and atypical presentations have been described for all three types of Usher syndrome. For example some individuals with mutations in type I genes may have a milder presentation (moderate hearing loss and/or a normal vestibular system). [usher-syndrome.org]

Over several years the blinds spots get bigger, and more develop until a ring-shaped blind spot is present. [dbproject.mn.org]

Back to top What treatments are available? While there are no treatments for Usher syndrome, intensive research is underway to discover the causes of and treatments for all types of the disease. [blindness.org]

Currently there is no cure or effective treatment for Usher Syndrome Type 1 Evaluation for severity of condition includes: Auditory, Vestibular function and Visual. [mazornet.com]

The best treatment involves early identification so that educational programs can begin as soon as possible. [ourmed.org]

Research using mouse models will help determine the function of Usher genes and inform potential treatments. [nidcd.nih.gov]

Prognosis The prognosis mainly depends on the progression of the visual loss: blindness occurs in almost all cases between 50 and 70 years of age. The documents contained in this web site are presented for information purposes only. [orpha.net]

What is the prognosis for a person with Usher Syndrome Type 1F? Usher syndrome type 1F causes severe hearing and vision impairment, however it does not affect one’s lifespan or intelligence. [jscreen.org]

But they struggled mightily with the added prognosis of Usher Syndrome Type 1: foremost, vision loss due to retinitis pigmentosa, or RP, a degenerative condition of the retina which begins in early adolescence and leads to blindness. [southcoasttoday.com]

[…] third decade) Visual field loss Appears mid-childhood Less than 20 degrees probable by mid 20's Slower, but legal blindness probable at some point Central visual acuity Progressive loss with early development of cataracts Less severe but great variation Prognosis [tsbvi.edu]

Again, the prognosis of eventual blindness comes as a shock. [asha.org]

Etiology So far, mutations in five genes ( MYO7A, USH1C, CDH23, PCDH15, USH1G ) and one locus ( USH1E ) have been implicated in US type 1. [orpha.net]

Our understanding of, and ability to test for, the underlying etiology of syndromes has been greatly enhanced by the study of the human genome and proteins necessary for normal development. [asha.org]

Since they thought the etiology of the hearing loss was Connexin 26, no one ever mentioned Usher or looked into it. At age 12, the female twin starting having difficulty with her night vision. She wore corrective lenses as well. [audiologyonline.com]

There can be several etiologies behind deafblindness, but Usher syndrome is one of the most common causes ( Pennings, 2004 ; Sadeghi, 2005 ). [journal.frontiersin.org]

Summary Epidemiology Prevalence is estimated at 1/30,000. US is the most common cause of hereditary combined deafness-blindness. Clinical description Onset usually occurs during childhood. [orpha.net]

Epidemiology The incidence is about 1 in 25,000. About 3-6% of hearing impaired children have the condition. Types 1 and 2 are more common than type 3 and together account for 90-95% of Usher's syndrome and about 10% of all children born deaf. [patient.info]

This requires that the audiologist be familiar with the genetic epidemiology of hearing loss and resources for referral and information. [asha.org]

However, early diagnosis is important in order to attenuate the far-reaching consequences of this condition and to take preventative measures. [hear.com]
