Because MS patients frequently report visual acuity disturbances, neuropsychologists often screen patients for severe visual acuity disturbances and tailor test batteries that minimize the need for intact vision. Less is known about how mild visual acuity disturbances may influence neuropsychological test performance. This study examined the extent to which mild visual acuity disturbances influence performance on visually-based tests of complex attention. Relapsing-remitting and secondary progressive MS patients who reported adequate vision were recruited for this study. A battery was administered that included the oral version of the Symbol Digit Modalities Test (SDMT), the Visual Elevator (VE) subtest from the Test of Everyday Attention, and a reduced near vision eye chart. Results suggested that, in addition to measuring higher order cognitive processes, visual tests of attention are sensitive to mild primary visual disturbances in MS.
由于多发性硬化症（MS）患者经常报告视力障碍，神经心理学家通常会对患者进行严重视力障碍筛查，并调整测试组合，以尽量减少对完好视力的需求。关于轻度视力障碍如何影响神经心理学测试表现，人们了解得较少。本研究调查了轻度视力障碍在多大程度上影响基于视觉的复杂注意力测试的表现。本研究招募了报告视力正常的复发缓解型和继发进展型MS患者。实施了一套测试组合，包括符号数字模态测试（SDMT）的口语版本、日常注意力测试中的视觉电梯（VE）子测试，以及简化的近视力检查表。结果表明，除了测量高阶认知过程外，注意力的视觉测试对MS中的轻度原发性视觉障碍也很敏感。
