Usher syndrome is the most common genetic disease impacting eyesight and hearing. The main symptoms of Usher syndrome are loss of sight and vision from an eye disease called pigment retinitis or RP. Loss of vision from RP can begin in early childhood or adolescence.
The main visual symptom of Usher syndrome is loss of eyesight from pigment retinitis or RP.
There is no known cure for Usher syndrome or pigment retinitis. The best treatment includes early diagnostics, so that the preparation of the patient for the consequences of the disease can begin as early as possible, depending on the degree of vision loss, age and the ability of the child. Treatment may include education for using Braille for reading. In recent years, genetic diseases such as RP and Usher syndrome have been successfully treated with genetic therapy. It is likely that such treatment can be successful in 100% of cases in the near future.
Some research shows that vitamin A can slow down the development of some types of RP. Your ophthalmologist can advise you for the risks and benefits of using vitamin A. Using too much vitamin A can be toxic, while proof of the effects of vitamin A on RP are not consistent.
