Spontaneous palinopsia (visual perseveration) and bitemporal visual extinction provoked only by ocular fixation developed in a patient with multiple sclerosis who had chronic bilateral retrobulbar optic neuritis. There were no signs of hemispheral compromise. The intermittent visual symptoms seemingly arose from the lesioned optic nerves, but were probably integrated at a cortical level. Palinopsia, classically considered diagnostic of posterior hemispheral cortical lesions, can also occur in patients with peripherally placed lesions of the visual pathways.
一名患有慢性双侧球后视神经炎的多发性硬化症患者出现了自发的持续性视觉（视觉留存）以及仅在眼球固定时诱发的双颞侧视觉消失。没有半球受损的迹象。间歇性视觉症状看似源于受损的视神经，但可能是在皮质水平整合的。持续性视觉，传统上被认为是后半球皮质病变的诊断依据，也可发生于视觉通路外周部位病变的患者。
