Abstract
Purpose: :
To evaluate the correlation between the change of intraocular pressure (IOP) and choroidal thickness (ChT) in patients with chronic renal failure during hemodialysis
Methods: :
Blood pressure, serum osmolality and complete ophthalmological examination together with IOP, central corneal thickness (CCT) and ChT measurements were performed for each patient both before and after HD sessions.
Results: :
Forty eyes of 20 patients were enrolled in the study. Mean IOP significantly decreased from 14.9 ± 2.4 to 14.3 ± 2.2 mmHg after hemodialysis (paired t test, P = 0.005). ChT (from 351.11 ± 33.02 to 305.90 ± 24.72 μm (paired t test, P=0.000)), blood pressure and serum osmolality also decreased significantly (P<0.001). There was no significant alteration was detected in CCT (P>0.005). Change in IOP was found to be correlated with ChT change. (r = 0.391, P = 0.013)
Conclusions: :
There was a significant decrease of ChT measurement followed by an IOP decrease during the hemodialysis. Decreased choroidal volume due to hemodynamic forces may be enrolled in the mechanism of IOP decrease after the hemodialysis.
