Three cases of cortical blindness complicating eclampsia are described, with magnetic resonance imaging (MRI) and X-ray computed tomography (CT). The correspondence of MRI lesions (hyperintense on T2 weighted, and hypointense on T1 weighted sections) and low attenuation lesions on CT scan indicated ischaemia rather than haemorrhage as the pathological mechanism.

本文描述了3例子痫并发皮质盲的病例，并进行了磁共振成像（MRI）和X射线计算机断层扫描（CT）检查。MRI病变（T2加权像上呈高信号，T1加权像上呈低信号）与CT扫描上的低密度病变相符，提示病理机制为缺血而非出血。
