Best corrected visual acuity improved Pearson’s (in case of normally distributed data) or from 0.5 ± 0.2 LogMAR at baseline to 0.4 ± 0.2 LogMAR Spearman’s (in case of non-normally distributed data) at the end of the study (P = 0.001). Mean OSDI score correlation coefficients. P < 0.05 were considered as was 47.5 ± 7.2 at baseline and 42.7 ± 7.1 at the end of statistically significant. study (P < 0.001). There was a significant increase in Schirmer test scores from baseline (4.6 ± 1.3 mm) to the end of the study (5.0 ± 1.3 mm) (P < 0.001). tCsA RESULTS therapy was associated with a significant decrease in tear A total of 36 eyes from 36 patients with mean age osmolarity (from 301.7 ± 11.5–286.3 ± 7.9 mOsmol/L, of 47.1 ± 6.5 years were included in this study.
