The state of the eyes in patients with end-stage chronic renal failure depending on the method of renal replacement therapy

Aim. To assess the state of the organ of vision in patients with end-stage chronic renal failure, who are on renal replacement therapy with hemodialysis and peritoneal dialysis. Methods. Examined were 35 patients with end-stage chronic renal failure. The first group consisted of 20 patients receiving renal replacement therapy with hemodialysis, the second group consisted of 15 patients treated with continuous ambulatory peritoneal dialysis. In addition to the standard ophthalmologic techniques (visual acuity, tonography, perimetry, biomicroscopy and ophthalmoscopy) conducted were optical coherence tomography and photographic imaging of the retina. The following data were also taken into account: arterial blood pressure, blood hemoglobin, creatinine and urea levels and indicators of phosphorus-calcium metabolism. Results. Regardless of the method of blood dialysis of all patients had decreased corrected visual acuity. In the patients of the first group it was 0.88±0.13, in the second group - 0.71±0.19. Also in both groups revealed was a concentric narrowing of the visual fields by 5-10%. Conclusion. In patients on hemodialysis, revealed was more severe course of retinopathy; in patients on continuous peritoneal dialysis, the most frequently encountered was swelling of the retina, metastatic calcification manifested to a lesser extent.
