AIM:To investigate the relationship among blood pressure,proteinuria,edema and fundus changes of the patients with pregnancy hypertension syndrome(PIHS).·METHODS:We carried a retrospective analysis of the relationship among blood pressure,proteinuria,edema and fundus changes.The fundus was examined by the direct ophthalmoscope.·RESULTS:Fundus was normal in 112 patients (32.0% )and retinopathy was in 238 patients(68.0%).In the four degrees of PIHS patieints (gestational hypertension group,slight pre-eclampsia group,severe pre-eclampsia group and eclampsia group),the incident rates of fundus changes were 52.5%,60.0%,70.3% and 100% respectively,and there was great significant difference among four groups.·CONCLUSION:Fundus change is related to the elevation of blood pressure.Fundus changes are more serious,incidence of proteinuria and edema become more higher.So fundus change is an important sign to reflect lesion of organs.
