先天性眼震是一种伴有视力减退的眼球运动障碍。其发病率的估计差异甚大,1∶350～1∶20,000。在英格兰及威尔士眼球震颤是造成视力障碍的第4种主要原因(11.2-14%)。视力下降主要是由于眼球震颤,使注视物在中心凹停留时间短,物像运动而引起视物不清。作者提出一种新方法,用听觉反馈技术训练病人控制眼震,使其视觉敏感度改善。也就是使病人听到自己的眼球运动,用这种反馈信号来 Congenital nystagmus is a condition associated with vision loss eye movement disorders. The incidence of the estimated difference is very large, 1: 350 ~ 1:20,000. Nystagmus in England and Wales is the fourth leading cause of visual impairment (11.2-14%). Visual acuity is mainly due to nystagmus, so that the fixation in the fovea stay short time, object motion caused by blurred vision. The authors propose a new method to train nystagmus using auditory feedback techniques to improve visual acuity. That is to make the patient hear his eye movement, with this feedback signal
