Abstract

To compare the characteristics of dry eye (DE) patients who did and did not satisfy the 2016 American College of Rheumatology (ACR)-European League Against Rheumatism (EULAR) classification criteria for primary Sjögren's syndrome (SS) among patients with pre-existing SS diagnosed according to the 2012 ACR criteriaThis cross-sectional study evaluated 91 patients with pre-existing SS and 55 with non-SS DE. Patients with SS were divided into 2 groups according to whether they met the revised 2016 ACR-EULAR classification criteria for primary SS. Group 1 (n = 71) was comprised of patients who satisfied the revised 2016 criteria and group 2 (n = 20) was comprised of patients who did not satisfy the newly revised criteria. Group 3 consisted of 55 patients with non-SS DE. The ocular surface disease index (OSDI) score, tear break-up time (TBUT), Schirmer score, tear clearance rate (TCR), and corneal and conjunctival staining scores were evaluated and compared between the groups. Laboratory profiles, including antinuclear antibodies, rheumatoid factor levels, erythrocyte sedimentation rate, and C-reactive protein levels, and focus scores were analyzed.TBUT, Schirmer, and corneal/conjunctival staining scores were significantly worse in both groups of patients with SS (groups 1 and 2) than in those with non-SS DE (group 3). However, there were no significant differences between groups 1 and 2 in laboratory findings as well as in ocular surface findings, including OSDI, TBUT, Schirmer score, TCR, and corneal/conjunctival staining scores. The focus score, which shows the level of lymphocytic infiltration in the salivary glands, was higher in group 1 than in group.Of the patients with pre-existing SS who were diagnosed according to the 2012 ACR classification, patients who did not satisfy the 2016 ACR-EULAR classification criteria for primary SS showed similar ocular surface parameters and laboratory findings to patients who did meet the revised classification, except for focus score. There is no need to change the direction of treatment of DE in patients with pre-existing SS who did not meet the revised 2016 ACR-EULAR criteria.
