Fourteen heterozygous carriers of Usher's syndrome were evaluated by ophthalmoscopy and dark adaptation testing. The normal findings in our study are discussed and compared with those of previous reports, which suggested that abnormal dark adaptation thresholds and fundus abnormalities may be seen in heterozygotes.
