对颈动脉短暂性脑缺血发作（TIA）或轻微卒中患者中可发现无症状视野缺损的假设进行了检验。 连续22例TIA男性患者和18例颈动脉区轻微卒中患者进行了视野检查，脑计算机断层扫描和局部脑血流检查。 在许多TIA和轻微卒中患者中发现无症状视野缺损，分别为29%（5/17）和57%（8/14）（NS）。 85%（11/13）的暗点仅位于或主要位于视野的上部（绝对缺陷P = 0.008，相对缺陷P = 0.03）。 我们的结论是，颈动脉区TIA和轻微中风患者都有很高的频率无症状的视野缺损，主要位于视野的上部。
The hypothesis that asymptomatic visual field defects can be found in patients with carotid transient ischaemic attacks (TIA) or minor strokes was tested. Twenty-two consecutive male patients with TIA and 18 patients with minor strokes from the carotid artery territory were examined by perimetry, cerebral computerised tomography and regional cerebral blood flow. Asymptomatic visual field defects were found in many TIA and minor stroke patients, 29 % (5/17) and 57 % (8/14), respectively (NS). Eighty-five per cent (11/13) of the scotomas were solely or predominantly located in the upper part of the visual field (P = 0.008 for absolute defects and P = 0.03 for relative defects). We conclude that both carotid territory TIA and minor stroke patients have a high frequency of asymptomatic visual field defects, predominantly located in the upper part of the visual field.
