A new approach designed to establish the most suitable area for eccentric viewing and to teach and train patients with severe age-related macular degeneration (AMD) to use the eccentric viewing technique is described. Using a computer and video display based system, as well as software written specifically for this purpose, we investigated and trained ten consecutive patients with AMD. The patients were 80.1 + or - 5.6 years old, on average. All of them had an absolute central scotoma. Mean visual acuity was 0.035 + or - 0.016. After 30 min of testing, instruction and reading on the screen, followed by 2.6 + or - 0.69 one-hour training sessions, on average, with the low vision therapist, reading newspaper and book texts with the aid of hyperoculars or aplanatic systems and a very short reading distance, the patients achieved a reading speed of 58.9 + or - 19.7 words/min, significantly (p<0.001) higher than the initial speed when reading on the screen, 11.5 + or - 4.5 words/min.
本文描述了一种新方法,旨在确定偏心注视的最合适区域,并对患有严重年龄相关性黄斑变性(AMD)的患者进行偏心注视技术的教学与训练。我们使用基于计算机和视频显示器的系统以及专门为此编写的软件,对连续10例AMD患者进行了研究和训练。患者平均年龄为80.1±5.6岁。他们均有绝对中心暗点。平均视力为0.035±0.016。在进行30分钟的屏幕测试、指导和阅读后,平均接受2.6±0.69次与低视力治疗师进行的一小时训练课程,借助高眼透镜或消球差系统以及非常短的阅读距离阅读报纸和书籍文本后,患者的阅读速度达到了58.9±19.7字/分钟,显著高于(p<0.001)最初在屏幕上阅读时的速度11.5±4.5字/分钟。
