摘　　要：目的分析4年来我科就诊的脑外伤患者的视野情况。方法汇总2008年9月至2012年9月于我科就诊的脑外伤患者的视野情况，对资料进行分析。结果57例中，视野正常者44例（77．2％），视野异常者13例（22．8％）。13例视野异常的患者中，视神经损伤导致单眼全盲者6例（46．1％），多发脑挫裂伤致双眼生理盲点扩大者4例（30．8％），脑挫裂伤损伤枕叶导致双眼同侧偏盲伴黄斑回避者2例（15．4％），脑挫裂伤损伤顶叶致双眼同侧的下象限偏盲者1例（7．7％）。结论伤及视路的颅脑外伤可引起视野的改变，视野的具体形态由损伤的部位和范围决定。脑外伤引起的视野缺损中，视神经损伤引起的视野改变最常见。对于脑外伤患者来说，视野检查对临床诊治有重要的指导意义。Objective To analyze the visual field of patients with brain trauma in our department in the recent 4 years. Methods Visual field data of patients with brain trauma from September 2008 to September 2012 was collected and analyzed. Results In 57 patients, 44 patients （77.2%） were with normal visual field, and 13 patients （22.8%） were with abnormal visual field. In 13 patients with abnormal visual field, 6 cases （46. 1% ） were with unilateral total blindness because of optic nerve damage, 4 cases （30.8%） was with bilateral enlarged physiological blind spot because of muhiple brain contusion and laceration, 2 cases （ 15.4% ） were with bilateral homonymous hemianopia and macular sparing because of occipital lobe damage, and 1 case （7.7%） was with bilateral inferior hemianopsia because of parietal lobe damage. Conclusion Brain trauma which damages the optic pathway can cause the visual field change, and the visual field shape depends on the damage location and size. Among the brain trauma that causes visual field loss, optic nerve damage is more common. In a word, visual field examination has important guiding significance in the diagnosis and therapy for patients with brain trauma.
