Thirty-five children under 15 years of age with optic nerve injury are prospectively studies for their clinical presentation, radiological findings, visual evoked potentials and outcome. Over 50% were under 10 years of age. In half of the children, injury was due to fall from a height. Fracture of the skull was recorded in a third of the patients, and optic canal fracture was seen only in three children. Visual Evoked Potentials (VEP) were record in 30 children and were repeated several times in first three weeks. All the patients received corticosteroids and optic canal decompression was not carried out routinely. Overall spontaneous visual recovery was observed in 12 patients. Among the 30 children in whom Veps were recorded, 17 children had repeatedly absent VEP, and none of the children showed wave formation, 10 (77%) had visual recovery. Only in 5 patients an optic canal decompression was carried out several weeks after injury. This study brings out the role of VEP in children with optic nerve injury.
对35名15岁以下视神经损伤儿童进行前瞻性研究,观察其临床表现、影像学检查结果、视觉诱发电位及预后情况。超过50%的儿童年龄在10岁以下。半数儿童的损伤是由于高处坠落所致。三分之一的患者记录有颅骨骨折,仅3名儿童可见视神经管骨折。对30名儿童记录了视觉诱发电位(VEP),并在最初三周内多次重复检查。所有患者均接受了皮质类固醇治疗,未常规进行视神经管减压术。12例患者出现了视力自发恢复。在记录了VEP的30名儿童中,17名儿童的VEP多次缺失,且均未显示波形,其中10名(77%)视力恢复。仅5例患者在受伤数周后进行了视神经管减压术。本研究揭示了VEP在视神经损伤儿童中的作用。
