Abstract

Introduction. Ocular microvascular changes can be related to kidney deterioration
in chronic kidney disease (CKD). We aimed to identify the association between retino-choroidal
parameters and kidney deterioration in diabetics and non-diabetics.
Methods. The study group consisted of CKD patients (cross-sectional study) with arterial
hypertension
with different stages of CKD. Complete eye examination was completed with optical
coherence tomography angiography (OCTA) scans of the macular region. According to the value of
glomerular filtration rate (GFR) and albuminuria, patients were divided into groups: low GFR
(<60ml/min) and high GFR (>60ml/min) and CKD patients without albuminuria and CKD with
micro or macroalbuminuria.
Results. One hundred and six eyes of 106 chronic kidney disease patients were evaluated. The mean
retinal thickness in GFR <60 ml/min group was 275,73±9,65 micron (μ), whereas in a GFR >60 ml/min
group was 274,36±10,77 μ. OCTA showed lower deep vascular density (DVD ) in CKD with albuminuria
versus CKD without albuminuria group (p < 0.001). Albuminuria was inversely related to
choroidal and retinal thickness measures of superficial (SVD) and DVD .
Conclusions. CKD is associated with retinal diluting and decreasing kidney function with reduction
of retinal and choroidal vascular density.
