Purpose: To screen severe to profound, preverbal hearing-impaired children for Usher syndrome by ophthalmologic examinations, including electroretinographic testing. These patients are especially good candidates for early cochlear implants, which will improve listening and spoken language skills. Methods: Consecutive patients over 2 years of age, given a diagnosis of severe to profound, preverbal hearing loss, were screened for Usher syndrome by a complete ophthalmologic examination including an electroretinogram. Results: Five of 48 patients screened (10.4%) were diagnosed with Usher syndrome and received cochlear implants. Conclusion: All children with severe to profound, preverbal sensorineural hearing loss should be screened for Usher syndrome by ophthalmologic examination including electroretinogram.
