Visual fields were examined with a tangent screen in 54 patients with multiple sclerosis (MS) or optic neuritis (ON). Visual fields were abnormal in all patients with definite MS, 94% with probable MS and 81% with possible MS. Three-quarters of the MS patients with no history of visual symptoms had abnormal fields. The commonest defect found was an arcuate scotoma. As a diagnostic test of visual pathway involvement in MS, tangent screen examination compares favourably with more sophisticated methods.
使用切线屏对54例多发性硬化症(MS)或视神经炎(ON)患者进行了视野检查。所有确诊为MS的患者视野均异常,可能患有MS的患者中94%视野异常,可能患有MS的患者中81%视野异常。四分之三无视觉症状病史的MS患者视野异常。最常见的缺陷是弓形暗点。作为MS视觉通路受累的诊断测试,切线屏检查与更复杂的方法相比具有优势。
