[Patients on dialysis--late fundus controls (author's transl)]

In 102 patients on dialysis for renal failure late fundus controls have been done to studie the response of retinal vessels to blood pressure reduction. In 52 patients follow up studies were possible. Only 4 patients showed reversible changes of the vessels, in 4 other patients changes increased. In the majority of the patients hypertensive vascular changes (stage I or II) remained unchanged. Young age and deep diastolic pressure seems to be necessary for normalization of the fundus vessels. Vessel changes did not improve if the diastolic pressure was 90--100 mmHg and more.
