LOW VISION READING: OPTIMIZING VISUO-MOTOR PERFORMANCE

独立和复兴的一个重大障碍 视觉障碍是指他们阅读文本的能力的丧失。尽管 对此，人们对视网膜的轨迹和视网膜运动知之甚少。 我们日益增长的老年黄斑患者的阅读 疾病。扫描激光眼底镜检查提供了一种独特的手段 获得这一数据，因为它允许确定视网膜轨迹 视觉缺陷，测量视网膜上的视力分布，以及 在阅读过程中直接观察视网膜运动。我们建议使用 在一项研究中扫描激光眼底镜以获得此信息(1) 确定黄斑患者的最佳视网膜位置和运动 疾病，(2)分析文本方向、大小和 移动对于特定的暗点大小和位置是最有效的， 以及(3)研究训练病人的程序以优化 残留的视网膜功能。这项研究带来的其他长期好处 包括开发更有效的低视力辅助设备和更多 为视障人士提供有效的文本显示。

A significant obstacle to the independence and rehabilitation of the visually handicapped is a loss of their ability to read text. Despite this, little is known about the retinal loci and retinal movements used in reading by our increasing population of elderly patients with macular disease. Scanning laser ophthalmoscopy provides a unique means of obtaining this data since it permits determination of the retinal loci of visual defects, measurement of visual acuity profiles on the retina, and direct observation of retinal movements during reading. We propose to use scanning laser ophthalmoscopy to obtain this information in a study (1) to determine optimal retinal loci and movements for individuals with macular disease, (2) to analyze which combinations of text orientation, size and movement are most effective for particular scotomata size and locations, and (3) to investigate procedures for training patients to optimize residual retinal function. Additional long-term benefits from this study include the development of more efficient low vision aids and more effective text displays for the visually impaired.
