 [sher´merz]

There were no significant differences of Schirmer's test, BUT, and ocular surface damage score before and after treatment in both groups, similar to previous research by Akpek et al.
(38) But recent data show that supplementation with omega-3s can have a beneficial impact on dry eye syndrome by improving tear film breakup time and enhancing oily tear secretions (as measured by Schirmer's test).
Baseline characteristics of all the patients enrolled for the study with reference to Schirmer's test, TBUT test, and OSDI score were similar in the two groups as shown in Table 1.
Thereafter, the minor salivary glands regions were carefully dried with compressed air, and subsequently, the examiners placed a pre-weighed Schirmer's test strip (Ophthalmos Industries, Sao Paulo, SP, Brazil).
Mean scores on Schirmer's test (a measure of eye-surface wetness) improved by 2.7 mm over the 3 months of treatment, from a baseline of 8.3, compared with a 1.4-mm deterioration in the artificial tears group.
(6) The presence of dry eyes and mouth for 3 months, reduced unstimulated salivary flow and a positive Schirmer's test in the presence of auto-antibody anti-Ro (SSA) with exclusion of other secondary causes established the diagnosis of primary SS.
The Schirmer's test is still widely used for objective documentation of the ocular component of Sjogren's syndrome, but its poor specificity renders it inadequate for this purpose.
Criteria for chronic ocular GVHD: (1) new ocular sicca documented by low Schirmer's test with a mean value of <5 mm at 5 minutes or (2) a new onset of keratoconjunctivitis sicca detected by slit lamp exam with mean Schirmer's test values of 6 to 10 mm [6].
After half an hour interval, Schirmer's test was performed in which readings were taken after anaesthetising the eye ball and keeping the lids closed for 5 minute.
Ocular surface inflammation was controlled, and we observed longer BUT and higher Schirmer's test values.
