Abstract
This case report demonstrates retinal vasospasm during a period of visual disturbance in a patient with preeclampsia. Doppler assessment of the orbital vasculature was performed during and after the episode. Central retinal artery blood velocity increased, and resistance decreased, after resolution of symptoms. Visual disturbances in preeclampsia may be associated with retinal artery vasospasm and ischemia.
摘要
本病例报告展示了一名先兆子痫患者在视觉障碍期间出现的视网膜血管痉挛。在发作期间及之后对眼眶血管系统进行了多普勒评估。症状缓解后，视网膜中央动脉血流速度增加，阻力降低。先兆子痫中的视觉障碍可能与视网膜动脉血管痉挛和缺血有关。
