[The relationship between ophthalmoscopic changes and classification of toxemia in toxemia of pregnancy].

Based on ophthalmoscopic findings, 30 toxemic patients were divided into three types: R-type; retinal vascular occlusion type, C-type; choroidal vascular occlusion type, R + C-type; mixed vascular occlusion type. R-type (5 cases) and R + C-type (7 cases) significantly correlated to superimposed preeclampsia. C-type (18 cases) significantly correlated to preeclampsia (pregnancy-induced hypertensive disorder: PIH). Clinical examinations (urine protein, platelet, fibrinogen, fibrin degradation product, partial thromboplastin time and prothrombin time) had no relation to the types of ophthalmoscopic classification. It was concluded that preeclampsia (PIH) and superimposed preeclampsia have different influences on the ocular fundus.
