Results of assessing the dynamics of ophthalmological complications in chronic kidney disease patients after kidney transplantation

Objective. The study objective was to investigate the dynamics of opthalmological complications in the non-diabetic end-stage chronic kidney disease in patients after kidney transplantation. Material and methods. A long-term observation was conducted to assess the changes in morphofunctional parameters of eyes in patients of the study group (after kidney transplantation, n=135 (269 eyes)) and the comparison group (continued on hemodialysis, n=81 (162 eyes)) over 18 months. Both general and specialized ophthalmological investigation methods were employed. Results. The observation showed a positive trend in patients after kidney transplantation, which was manifested by reduced corneal and conjunctival calcification. In the comparison group, both an increase and decrease in qualitative signs of retinopathy were seen as based on optical coherence tomography data, while in the study group, most retinopathy signs decreased, indicating a positive trend possibly brought about by the kidney transplantation. Analysis of optical coherence tomography quantitative parameters showed an improvement in central choroidal thickness and retinal nerve fiber layer thickness in the study group. Conclusion. Kidney transplantation in patients with the non-diabetic end-stage chronic kidney disease leads to a reduction in ophthalmological complications both in the anterior eye segment (reduced corneal and conjunctival calcification) and in its posterior segment (improved optical coherence tomography retinal parameters).
