Abstract:
Objective To study the visual electrophyological changes in patients with pregnancy-induced hypertension syndrome(PIH).Methods The visual evoked potentials (VEP) and electroretinogram (ERG) of 28 patients with PIH in 56 eyes were recorded.Results The patients with PIH had pathologic visual electrophysiologic abnormalities. The VEP N75 peak latency significantly increased(P<0.05), and the ERG b wave latency in patients with PIH showed remarkable difference(P<0.05).Conclusion Visual electrophysiological examination may be valuable in early diagnosis of retinal disfunction in patients with PIH.
