What is a characteristic of Usher's Syndrome?

Usher's Syndrome is characterized by a combination of hearing loss and vision impairment that typically progresses over time. The syndrome comprises three types, where individuals commonly experience congenital deafness or significant hearing loss from a young age, along with retinitis pigmentosa, a condition that leads to progressive vision loss, often beginning with night blindness and peripheral vision loss. The gradual loss of vision is a hallmark of this condition, occurring alongside the initial or progressive hearing deficits, which directly supports the identified characteristic of "deafness with gradual vision loss."

The other options do not accurately reflect the syndrome's characteristics. High visual acuity with stable hearing is inconsistent with the common experience of individuals with Usher's Syndrome, as the condition typically involves hearing loss and significant visual decline. Similarly, balance issues without hearing impairment do not align with the diagnosis, since balance problems can arise from the vestibular dysfunction associated with Usher's, which involves both hearing and vision loss. Lastly, the assertion that it only affects vision is incorrect, as Usher's Syndrome is defined precisely by both auditory and visual impairments, making the identification of the correct characteristic critical in understanding the condition.
