How do you tell if someone has usher syndrome?

Usher syndrome is characterized by a combination of hearing loss and vision problems. Individuals may have congenital deafness or hearing impairment, along with progressive vision loss due to retinitis pigmentosa, which typically starts with night blindness and peripheral vision loss. A clinical evaluation by an audiologist and an ophthalmologist, along with genetic testing, can confirm the diagnosis. Observing these symptoms in conjunction can indicate the presence of Usher syndrome.
