Retinal vasospasm associated with visual disturbance in preeclampsia: color flow Doppler findings.
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.
