Table 3.

Comparison of dry eye disease (DED) parameters between patients and controls. Statistically significant differences were found between the patient and healthy control groups in dry-eye quality of life score (DEQS) and all ophthalmological tests. * Statistically significant difference by the Mann–Whitney U test (p < 0.01). Data are expressed as the mean with SD. BUT: tear break-up time, FS: fluorescein staining score, LG: lissamine green staining score.

Scores	Patients (n = 11 eyes)	Controls (n = 12 eyes)	p Value

BUT (sec)	2.36 ± 1.43	6.0 ± 1.28	<0.0001 *
Schirmer (mm)	2.73 ± 1.90	14.75 ± 10.73	<0.0001 *
FS (pts)	4.73 ± 2.72	0.08 ± 0.29	<0.0001 *
LG (pts)	6.46 ± 4.39	0.0 ± 0.0	<0.0001 *
