[Visual function in patients with neuroretinopathy on regular dialysis treatment]

Eight patients included in a regular dialyzation programme who developed neuroretinopathy were subjected to improved dialyzation treatment. It involved variation of sodium and variation of ultrafiltration. After regression of acute symptoms on the fundus in all patients a vision of 6/6 was achieved. Patients with neuroretinopathy have a markedly reduced contrast sensitivity. The latter increases considerably after absorption of the oedema, although it does not attain values recorded in healthy subjects.
