Usher syndrome

How is it diagnosed?

Diagnosis of Usher syndrome may occur while the child has no visual problems, by means of electrical tests of retinal function (electroretinogram or ERG). More often, diagnosis may be delayed until the visual problems have become significant because peripheral and night vision are not routinely tested in school children, and because the optimal age for such screening testing is unknown.
