Retrobulbar neuritis is a common clinical manifestation of multiple sclerosis. We evaluated and compared the results of visual field and fundus examinations, visual evoked response and nuclear magnetic resonance of the brain in 37 patients with the diagnosis of multiple sclerosis and retrobulbar neuritis. Diffuse, peripheral scotomas seemed to be the most often found scotomas on perimetry in these patients. In contrary, central scotomas formed just a little part of the visual field defects. Each threshold increasing of 0.10 log. units on perimetry was followed by increased latencies of 2.5 ms. Each other central scotoma on perimetry decreased the visual acuity of the patient for 1.6 lines on the Snellen chart. The central visual field examination without periphery in the patients with multiple sclerosis and retrobulbar neuritis seems to give false negative results.
球后视神经炎是多发性硬化的常见临床表现。我们评估并比较了37例诊断为多发性硬化和球后视神经炎患者的视野和眼底检查结果、视觉诱发电位及脑部核磁共振结果。弥漫性周边暗点似乎是这些患者视野检查中最常发现的暗点。相反,中心暗点仅占视野缺损的一小部分。视野检查中每增加0.10对数单位的阈值,随后潜伏期增加2.5毫秒。视野检查中的其他中心暗点会使患者在斯内伦视力表上的视力下降1.6行。对多发性硬化和球后视神经炎患者进行不包括周边的中心视野检查似乎会得出假阴性结果。
