Twenty-one eyes of thirteen patients suffering from optic neuritis were examined with the Octopus automated perimeter and pattern visually evoked cortical potentials. All eyes had visual acuity of 0.2 or better. Visual field examination was measured by program 31 or 33, which tests the central 30-degree fields in a 6-degree grid. Pattern evoked potentials were obtained by reverse checkerboard stimulation of 3 rev/sec. A prolonged P100 latency was related to at least one abnormal point in the central nine points of program 31. All seven eyes with one abnormal point in the center had a delayed peak latency. The patients with either the normal central nine points of program 31 or normal peak latency had visual acuity of 0.6 or better. The graphs of visual acuity by Octopus compared with pattern evoked potential were very similar. With program Delta, the sensitivity loss ratio, i.e., the ratio of the mean loss at eccentricity of less than 10 degrees over less than 30 degrees, was related to the peak latency in optic neuritis caused by multiple sclerosis.
使用Octopus自动视野计和图形视觉诱发电位对13例视神经炎患者的21只眼睛进行了检查。所有眼睛的视力均为0.2或更好。视野检查采用程序31或33进行测量，该程序以6度网格测试中央30度视野。图形诱发电位通过3次/秒的反向棋盘格刺激获得。P100潜伏期延长与程序31中央九个点中至少一个异常点相关。中央有一个异常点的所有七只眼睛的峰值潜伏期均延迟。程序31中央九个点正常或峰值潜伏期正常的患者视力为0.6或更好。Octopus测量的视力与图形诱发电位的图表非常相似。使用Delta程序时，敏感性损失率，即小于10度偏心度处的平均损失与小于30度偏心度处的平均损失之比，与多发性硬化症引起的视神经炎的峰值潜伏期相关。
