Occurrence of neuroretinopathy in dialyzed patients.

In the last 11 years, the neuroretinopathy is reported to occur in 26 dialyzed patients, what represents 5.3% of all patients treated. During the last 4 years, the occurrence rate showed the decrease to 1.6%. The mentioned disease occurs most frequently by the first two years of treatment with dialysis. The averaged survival rate after the onset of neuroretinopathy is ranged as 19.4 mos. in 16 died patients. The disease occurred in 13 patients under the condition of normal diastolic pressure. Metabolic disorder characterized with high levels of serum nitrogenic substances may be further factor inducing the onset of neuroretinopathy backgrounded by cerebral oedema. Since neuroretinopathy consequentially worsens both the subjective (visual acuity, sensitivity to the contrast) and objective (electric activity) sight functions, the appropriate attempt is to be made in achieving rapidly retrogression of pathologic retinal changes by modification of dialysis process.
