PURPOSE/METHODS: Bilateral visual field defects resembling an hourglass could be produced by bilateral lateral geniculate lesions. We recently encountered such deficits in a 37-year-old woman after an episode of central pontine myelinolysis.
RESULTS/CONCLUSIONS: Automated static perimetry demonstrated the congruous visual field defects to involve both halves of the visual field. They were confirmed with kinetic perimetry, and they remained stable for four years. Magnetic resonance imaging demonstrated enhancing lesions characteristic of myelinolysis in each lateral geniculate.
目的/方法:双侧外侧膝状体损伤可导致类似沙漏形状的双侧视野缺损。我们最近在一名37岁女性发生中央脑桥髓鞘溶解症后遇到了这种缺陷。
结果/结论:自动静态视野检查显示一致性视野缺损累及视野的两半。动态视野检查证实了这些缺损,并且它们在四年内保持稳定。磁共振成像显示每个外侧膝状体内有髓鞘溶解的强化病变特征。
