The conditions of 70 patients with Usher's syndrome were studied by ophthalmic and neuro-otologic examinations. Two distinct clinical and presumed genetic types were discernible on the basis of differences in hearing impairment, vestibular sensitivity, and, to a lesser extent, deterioration in retinal photoreceptor function. Distinguishing these two types has relevance for both diagnosis and genetic counseling of patients with Usher's syndrome.
通过眼科和神经耳科学检查对70例患有Usher综合征的患者的病情进行了研究。根据听力损害、前庭敏感性以及在较小程度上视网膜光感受器功能的恶化情况,可辨别出两种不同的临床和推测的遗传类型。区分这两种类型对于Usher综合征患者的诊断和遗传咨询都具有重要意义。
