Correlations of the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) score with the clinical symptoms and signs. OSDI: Ocular Surface Disease Index; SANDE: Symptoms Assessment in Dry Eye; TBUT: tear break-up time; BCVA: best corrected visual acuity; LogMAR: logarithm of minimum angle of resolution; R: Spearman’s correlation coefficient. Higher scores in the NEI-VFQ-25 indicate better quality of life (note the negative correlations with OSDI, SANDE, corneal fluorescein staining, and BCVA).
