Assessment of Central Corneal Thickness in Adults With Indications For Kidney Transplantation and Commenting On Some Related Factors

Objectives: Central corneal thickness (CCT) is an important biological indicator of eyeball affecting intraocular pressure, which plays a vital role in glaucoma pathology. This study investigated the central corneal thickness in renal failure subjects with indications for kidney transplantation and commented on some related factors. Methods A cross-sectional descriptive study was conducted from January to June 2021 in Hanoi, Vietnam. Ninety-six adult patients with grade 3 and 4 renal failure indicated kidney transplantation had central corneal thickness measured. We investigated the mean value of central corneal thickness in patients with indications for kidney transplantation. The related factors were evaluated by multivariable linear regression. Results The mean thickness of the central cornea in the right eye was 529.3 ± 32 µm, and the left eye was 528.5 ± 32.1 µm, with no difference between the central corneal thickness in the two eyes. Corneal thickness has a positive correlation with IOP after dialysis and smoking habits, adjusted R 2  = 0.2405, has a negative correlation with age, adjusted R 2  = 0.2405, and with calcium concentration blood, adjusted R 2  = 0.032. Conclusion The thickness of the central cornea in patients with renal failure with indications for kidney transplantation in both eyes is similar. Factors related to corneal thickness are age, smoking habits, intraocular pressure after dialysis, and blood calcium levels.
