在美国，AMD是导致中心视力丧失的低视力的主要原因，并且与听力损失有很高的共同发生率。如果不考虑老年人的听力状况，就无法完全解决中央视力丧失对老年人日常功能的影响。我们研究了中央视力丧失和听力丧失对空间定位的影响，这是一种对社会互动和导航至关重要的能力。16名患有主要由AMD引起的中央视力丧失的老年人，有或没有共同发生的听力损失，完成了一项空间视野检查任务，其中他们口头报告了视觉或听觉目标的方向。听力测试是在光线昏暗的房间里睁着眼睛或蒙着眼睛进行的。23名视力正常、年龄匹配和听力匹配的对照受试者也完成了这项任务。中心视力丧失的受试者更容易错过视觉目标。随着暗点大小的增加，他们与对照组的视觉偏差也会增加。然而，这些缺陷并没有推广到声音定位。随着听力损失变得更加严重，声音定位变异性增加，这种关系并没有被共存的中央视力丧失改变。对于控制和中央视力丧失的主题，声音定位是不太可靠的，当受试者戴眼罩，可能是由于缺乏视觉上下文线索。虽然中心视力丧失损害视觉定位，但它不损害声音定位，也不妨碍视觉为声音定位提供有用的上下文线索。
In the United States, AMD is a leading cause of low vision that leads to central vision loss and has a high co-occurrence with hearing loss. The impact of central vision loss on the daily functioning of older individuals cannot be fully addressed without considering their hearing status. We investigated the impact of combined central vision loss and hearing loss on spatial localization, an ability critical for social interactions and navigation. Sixteen older adults with central vision loss primarily due to AMD, with or without co-occurring hearing loss, completed a spatial perimetry task in which they verbally reported the directions of visual or auditory targets. Auditory testing was done with eyes open in a dimly lit room or with a blindfold. Twenty-three normally sighted, age-matched, and hearing-matched control subjects also completed the task. Subjects with central vision loss missed visual targets more often. They showed increased deviations in visual biases from control subjects as the scotoma size increased. However, these deficits did not generalize to sound localization. As hearing loss became more severe, the sound localization variability increased, and this relationship was not altered by coexisting central vision loss. For both control and central vision loss subjects, sound localization was less reliable when subjects wore blindfolds, possibly due to the absence of visual contextual cues. Although central vision loss impairs visual localization, it does not impair sound localization and does not prevent vision from providing useful contextual cues for sound localization.
