Figure 1

Ocular surface parameter changes were observed in baseline, 2 weeks, 2 and 6 months after punctal plugs insertion. (A) Change in TMH (mm). After treatment, a significantly larger TMH was found in non-SS group comparing with SS group at every visit (all p < 0.05). In both groups, the TMH was improved at every visit compared to baseline (all p < 0.01). (B) Change in NIKBUT (sec). Non-SS group had a significantly longer BUT than that in the SS group at every visit. Compared with the baseline, there was statistically significant increase in NIKBUT at every visit in non-SS patients (p < 0.01, respectively) and in SS patients NIKBUT was improved at 2 weeks and 2 months (p < 0.01, respectively). (C) Change in SI T (mm). A significantly larger SI T was found in non-SS group comparing with SS group at every visit (all p < 0.01). The SI T score was improved at every visit compared to baseline in both groups (all p < 0.01). (D) Change in CFS score. There was a statistically significant decrease in the corneal staining score after the treatment, but the SS group showed higher score than the non-SS group (p < 0.01) and there was no CFS in non-SS patients. (&p < 0.05 in SS vs. non-ss, *p < 0.05 in SS vs. baseline, #p < 0.05 in non-SS vs. baseline).
