Among the patients we tested, most of those who had lost normal macular function developed extrafoveal retinal loci which resulted in strongly preferred viewing angles for steady fixation. These patients used these extrafoveal retinal loci to scan lines of characters in patterns similar to patients with normal macular function. Although the scanning speed of these patients was adversely affected by their large size scotomas, their reading accuracy was not necessarily reduced. The assessment of scanning and reading performance in this population requires careful measurement of the visual skills involved in reading.
在我们测试的患者中，大多数失去正常黄斑功能的患者形成了黄斑外视网膜位点，这导致了用于稳定注视的强烈偏好视角。这些患者使用这些黄斑外视网膜位点以类似于具有正常黄斑功能的患者的模式扫描字符行。尽管这些患者的扫描速度受到其大尺寸暗点的不利影响，但其阅读准确性不一定降低。对这一人群的扫描和阅读表现进行评估需要仔细测量阅读中涉及的视觉技能。
