Table 2. OSDI, TBUT and Schirmer values in control and study eyes.

	CRF (n = 35) (mean ± SD)	Controls (n = 31) (mean ± SD)	p-Value*
OSDI score	44.69 ± 17.81	24.05 ± 12.717	p < 0.001
TBUT (s)	9.86 ± 7.11	13.03 ± 5.91	p = 0.001
Schirmer test (mm)	14.89 ± 8.06	17.26 ± 7.68	p = 0.202

Notes: OSDI, Ocular surface disease index; TBUT, tear break-up time; CRF, chronic renal failure; SD, standard deviation.

*Comparisons with control eyes via Kruskal–Wallis test, p < 0.05 was considered statistically significant.
