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.

独立和恢复的一个重大障碍是， 视力障碍是指他们丧失了阅读文字的能力。 尽管 这一点，很少有人知道的视网膜位点和视网膜运动中使用的 阅读受我国老年黄斑病变患者人群日益增多的影响 疾病 扫描激光检眼镜提供了一种独特的手段， 获得该数据，因为它允许确定视网膜位点， 视力缺陷，测量视网膜上的视敏度曲线，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（1）中，扫描激光检眼镜检查获得了这一信息， 确定最佳的视网膜位点和运动的个人黄斑 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， 和（3）调查培训患者优化的程序 残余视网膜功能 本研究的其他长期获益 包括开发更有效的低视力辅助设备， 为视障人士提供有效的文字显示。
