A rapid visual resolution test conducted on available equipment reveals the presence of rapid falloff in acuity in a case of probable multiple sclerosis. Intense large field illumination was used, and grating acuity was tested using laser red light. The effect is so large that minor anomalies (not subjectively appreciated) or the residuum of earlier minor attacks of retrobulbar optic neuritis can be readily detected. A related "visual fatigue or saturation-like syndrome" was described earlier. In bright environments these patients' vision fades. Briefly closing the eyes restores visual sensitivity. Providing filters or lowering the light level tends to maintain vision. This test must be studied intensively. It offers a noninvasive simple means of showing underlying anomalies in neural conduction of the visual signal. Such anomalies can be prognostic and previously have been revealed only with sophisticated electrophysiological techniques.
在现有设备上进行的一项快速视觉分辨率测试显示，在一例可能患有多发性硬化症的病例中，视力存在快速下降。使用了强的大视野照明，并使用激光红光测试光栅视力。这种影响非常大，以至于轻微异常（主观上未察觉到）或早期球后视神经炎轻微发作的残留症状都能很容易被检测到。之前曾描述过一种相关的“视觉疲劳或类似饱和综合征”。在明亮环境中，这些患者的视力会减退。短暂闭眼可恢复视觉敏感度。提供滤光片或降低光照水平往往能维持视力。必须深入研究这项测试。它提供了一种非侵入性的简单方法来显示视觉信号神经传导中的潜在异常。此类异常可能具有预后意义，而且以前只有通过复杂的电生理技术才能发现。
