RESUMEN
AIM: To investigate the risk factors for pregnancy induced hypertension retinopathy, and analyze its influence on maternal and child pregnancy outcomes. METHODS: A total of 100 patients with gestational hypertension who met the requirements of screening were selected, they were divided into two groups, without retinal lesion group (n = 29) and retinopathy group (n=71). The age, course of disease, gestational age, blood pressure, proteinuria and hematocrit in two groups were investigated. The risk factors were detected by single factor analysis, and then the study on independent risk factors were analyzed by Logistic regression analysis. At the same time,their influence on maternal and child pregnancy outcomes were investigated. RESULTS: The single factor analysis showed that except for age, the differences in the course of disease, gestational age, blood pressure, proteinuria and hematocrit were statistically significant (P < 0. 01). Logistic regression analysis showed that the course of disease, blood pressure, proteinuria and hematocrit were the risk factors of retinopathy, gestational age was a protective factor. Compared with the group without retinopathy, the incidence of preterm birth, placental abruption, postpartum hemorrhage, perinatal death in the patients with retinopathy significantly increased, and the difference were statistically significant(P<0.01),and there was a certain correlation between the extent of increase and the grade of retinopathy. CONCLUSION: Course of disease, blood pressure, proteinuria and hematocrit of patients with the hypertension of pregnancy are the risk factors of retinopathy,retinopathy has a serious adverse effect on maternal and child pregnancy outcomes.
