Abstract Purpose: To investigate the correlation between Sjögren syndrome (SS) duration and ocular surface parameters in patients with SS-related dry eye. Methods: We analyzed 108 eyes of 108 female patients with primary SS-related dry eye. Meibomian gland (MG) dysfunction, MG dropout, lipid layer thickness (LLT), partial and total blinking, and partial blinking rate (PBR) were measured using a LipiView® II ocular surface interferometer (TearScience, Morrisville, NC, USA). All patients underwent rheumatoid serologic tests and ocular surface assessments. The ocular surface assessment included the Standard Patient Evaluation of Eye Dryness (SPEED), Schirmer’s I test, non-invasive tear break-up time, and grading of corneal/conjunctival staining. The correlations between SS duration and MG dropout rates as well as other ocular surface parameters were determined. Results: The mean SS duration was 54.1±41.3 months. There was a strong positive correlation between SS duration and MG dropout (r = 0.766, p < 0.001). The average, maximum, and minimum LLTs showed a weak negative correlation with SS duration (r = -0.310, -0.211, and - 0.304, respectively, p = 0.014, 0.028, and 0.022, respectively) and MG dropout (r = -0.191, -0.326, and -0.299, respectively, p = 0.049, 0.002, and 0.009, respectively). Significant positive correlations were also observed between the SPEED scores and SS duration (r = 0.303, p = 0.042) and MG dropout (r = 0.450, p = 0.029). Conclusions: Longer durations of primary SS-related dry eye were associated with worse MG dysfunction.

Inflammatory Molecules

Abstract Purpose To compare the levels of inflammatory molecules in tear samples between patients with meibomian gland dysfunction (MGD)-related evaporative dry eye (EDE) and healthy subjects and to analyze the correlations between the levels of tear inflammatory molecules and ocular surface parameters. Methods A total of 30 MGD-related EDE patients (48 eyes) and ten healthy volunteers (15 eyes) were enrolled. Dry eye-related examinations and questionnaires were obtained from all participants. The levels of nine inflammatory molecules were determined through multiplex bead analysis. Results Inflammatory molecules including ICAM-1, IFN-γ, CXCL8/IL-8, IL-6, TNF-α and IL-12p70 were detected in 100% of the patients, while IL-1α, IL-1β and IL-10 were detected in 56.25%, 13.60% and 45.83% of the patients, respectively. Moreover, ICAM-1, IL-8, IL-6, TNF-α, IL-12p70 and IFN-γ were detected in 86.67–100% of the healthy subjects, and the detection rates of IL-10, IL-1α and IL-1β were below 50%. The levels of IL-8, IL-6, IFN-γ and ICAM-1 were significantly higher in the patient group compared with the control group. In addition, IL-8 and IL-6 were negatively correlated with Schirmer I test. Besides, IFN-γ was negatively correlated with tear film breakup time. Furthermore, ICAM-1 and IL-6 were positively correlated with meibography score. Conclusions Collectively, patients with MGD-related EDE had higher levels of inflammatory molecules in their tears, and some molecules were correlated with ocular surface parameters. These findings suggested that inflammation played an important role in MGD-related EDE, and several inflammatory molecules could be used in the diagnosis and the treatment of MGD-related EDE.

Abstract Background The aim of this study was to evaluate the effects of systemic parameters, laboratory findings, oral parameters, and other ocular surface parameters on ocular surface epithelial damage in patients with primary Sjögren’s syndrome (pSS). Methods A total of 82 dry eye disease (DED) patients with pSS were enrolled in this study. Ocular surface epithelial damage was measured by ocular staining score (OSS). Systemic parameters, laboratory findings including serologic markers, oral parameters, and other ocular surface parameters were collected. Other ocular surface parameter assessments such as the Schirmer’s test, fluorescein tear breakup time, meibomian gland examinations, noninvasive keratographic tear film break-up time measurements using the Keratograph® 5 M were performed, and the Ocular Surface Disease Index was determined. Results In a multivariate analysis, decreased age and increased duration of pSS were significantly related to increased logarithm-transformed OSS (β = -0.011, P = 0.043 and β = 0.003, P = 0.008). Among the ocular surface parameters, decreased fluorescein tear breakup time and increased MGD grade were significantly associated with increased logarithm-transformed OSS (β = -0.183, P < 0.001 and β = 0.192, P = 0.049). Conclusions Ocular surface epithelial damage in patients with pSS was associated with young age, long duration of disease, unstable tear film, and decreased meibomian gland function.

The Impact

AbstractPurposeTo analyze how ocular surface parameters correlate to pterygium and investigate the possible impact on tear film and meibomian glands.Methodswe investigated objective parameters of the ocular surface such as conjunctival hyperemia, tear film stability and volume, meibomian gland dysfunction, dry eye disease, corneal topography comparing healthy individuals and correlating with the pterygium clinical presentation.ResultsA total of 83 patients were included. Corneal astigmatism induction was 2.65 ± 2.52 D (0.4-11.8). The impact of pterygium on the ocular surface parameters compared to matched controls was seen in: conjunctival hyperemia (control 1.55±0.39/pterygium 2.14±0.69; p=0.0001), tear meniscus height (control 0.24±0.05 mm/pterygium 0.36±0.14mm; p 0.0002), meiboscore lower eyelid (control 0.29±0.64/pterygium 1.38±0.95; p 0.0001) and meiboscore upper eyelid (control 0.53±0.62/pterygium 0.98±0.75; p=0.0083). We found a high number of pterygium patients (88%) presented meibomian gland alterations. Interestingly, meibomian gland loss was coincident to the localization of the pterygium in 54% of the upper and 77% lower lids.ConclusionPterygium greatly impacts on ocular surface by inducing direct alterations in the pattern of meibomian glands besides corneal irregularities, conjunctival hyperemia and lacrimal film alterations, inducing significant symptoms and potential signs of dysfunction.
