Evaluation of uraemic patients undergoing haemodialysis

ABSTRACT

High incidence of uraemic patients in Egypt are suffered from severe visual deterioration in spite of having clear media. This deterioration is attributed to retinal vascular abnormalities, macular pigment degeneration and ischaemic changes of the choroid and optic nerve. To evaluate the causes and incidence of visual impairment in uraemic patients undergoing haemodialysis; this study was performed on fifty patients attending Al Zahraa University Hospital between [1994-1996]. Seventeen patients with duration of dialysis more than 30 months [group I] and thirty-three patients with duration of dialysis less than 30 months group [II]. Our Study proved that there are variable degrees of choroidal and macular fluoroangiographic changes together with a variety of field defects in both groups with a less severity in group II
