颅内肿瘤患者的视野情况分析

Vision field analysis of patients with intracranial tumor

目的:总结近4年来我科就诊的颅内肿瘤患者的视野情况。方法:汇总2008年9月～2012年9月就诊的颅内肿瘤患者的视野情况。结果:45例患者中,视野正常23例(51.1%),视野异常22例(48.9%)。异常视野中,双颞侧偏盲12例(54.5%),单眼颞侧偏盲4例(18.2%),双眼同向偏盲1例(4.5%),单眼颞上视野缺损1例(4.5%),单眼鼻下视野缺损1例(4.5%)。视野形态异常的患者中,鞍区肿瘤15例(68.2%)。26例鞍区肿瘤患者中,视野正常11例(42.3%),视野异常15例(57.7%)。结论:部分颅内肿瘤可引起视野改变,视野的具体形态由病变类型、病灶大小和压迫部位决定。其中,鞍区肿瘤占绝大多数,最典型的视野改变为双颞侧偏盲。视野检查有助于早期发现颅内肿瘤,甚至辅助定位病灶,为临床工作起一定的指导意义。

Objective To summarize the vision field of patients with intracranial tumor in our department in the recent 4 years.Methods Vision field data of patients with intracranial tumor from September 2008 to September 2012 was collected and analyzed.Results In 45 patients,23 patients(51.1%) were with normal vision field,and 22 patients(48.9%) were with abnormal vision field.In patients with abnormal vision field,12 cases(54.5%) were with bilateral temporal hemianopsia,4 cases(18.2%) were with unilateral temporal hemianopsia,1 case(4.5%) was with bilateral homonymous hemianopsia,1 case(4.5%) was with unilateral superior-temporal hemianopsia and 1 cases(4.5%) was with unilateral inferior-nasal hemianopsia.In patients with abnormal vision field,15 cases(68.2%) were with tumors in the saddle area.In 26 patients with tumors in the saddle area,11 cases(42.3%) were with normal vision field,and 15 cases(57.7%) were with abnormal vision field.Conclusion Some intracranial tumors can cause the change of vision field,and the vision field shape depends on the lesion type,size and pressed location.In these intracranial tumors,tumors in the saddle area are common,whose characterized vision field is bilateral temporal hemianopsia.Vision field examination is helpful in the early detection of intracranial tumor,and it even can locate the lesion,which has guiding significance in the clinical working.
