DESCRIPTION (Adapted From The Applicant's Abstract): This is a grant directed at the problem of reading in low vision patients. Specifically, the PI is interested in those cases where macular damage makes it necessary to read with peripheral retina. Reading is difficult under such conditions. Proposed research will investigate three hypotheses about the causes of that difficulty: Grouping/crowding effects are more damaging in the periphery. Consequently, Aim 1 seeks to minimize these effects. Peripheral representation of phase is inaccurate. Aim 2 will attempt to enhance reading speed by minimizing the need for phase information. Patients lack of practice with peripheral reading. Aim 3 will examine the effects of extensive practice with peripheral reading. Experiments will be carried out with normally-sighted subjects as well as with subjects having central scotomata.

描述（改编自申请人的摘要）：这是一个赠款指示 低视力患者的阅读问题。具体而言，PI是 感兴趣的是那些黄斑损伤的情况下，有必要阅读与 周边视网膜在这种情况下阅读是困难的。提出 研究将调查有关该困难原因的三种假设： 在外围，拥挤/拥挤效应更具破坏性。因此，Aim 1、尽量减少这些影响。相位的外围表示是 不准确。目标2将尝试通过最小化需要来提高阅读速度 相位信息。患者缺乏周边阅读的练习。目标3 我们将检验广泛练习周边阅读的效果。 实验将在视力正常的受试者以及 有中心暗点的受试者。
