A new pilot study suggests that tear film lipid irregularity, rather than tear volume alone, may be a key feature of dry eye disease associated with Sj\u00f6gren\u2019s syndrome (SS). The research used recently developed technology called the Tear Film Imager<\/a> (TFI), a high-resolution, non-contact device that is not FDA-approved in the United States. The TFI uses spectral interference and reflective analysis of ultra-thin tear film layers to measure tear film dynamics while patients blink naturally. In this study, it showed that patients with Sj\u00f6gren\u2019s syndrome had significantly greater lipid map uniformity abnormalities than healthy controls, suggesting lipid layer dysfunction could be an important therapeutic target.<\/p>\n

By capturing tear film sublayers dynamically and simultaneously, an investigational device called the Tear Film Imager revealed that lipid layer dysfunction may play a bigger role in the pathophysiology of DED in Sj\u00f6gren\u2019s patients than previously thought. These images from the study show a comparison of the lipid layer thickness maps between a participant with Sj\u00f6gren\u2019s syndrome (A) and a matched control subject (B).\u00a0Photo:\u00a0Goulak AM, et al.

Published recently in Journal of Clinical Medicine, the cross-sectional study enrolled 15 patients with confirmed Sj\u00f6gren\u2019s syndrome and symptomatic dry eye disease (mean age: 53.4; 86.7% female) and compared them with 15 age-matched healthy controls (mean age: 52.3; 73.3% female). In addition to TFI imaging, Sj\u00f6gren\u2019s patients underwent Ocular Surface Disease Index testing, Schirmer\u2019s testing with anesthesia, tear osmolarity measurement and tear breakup time. The controls underwent TFI imaging and anterior segment examination.<\/p>\n

The TFI is designed to provide nanometer-resolution assessment of several characteristics of individual tear film layers: mucoaqueous layer thickness, muc-aqueous layer thinning rate, lipid layer thickness, lipid map uniformity, lipid breakup time and interblink interval during natural blinking. It also generates a 3D map of the lipid layer, allowing clinicians to visualize lipid uniformity across the tear film.<\/p>\n

The main finding of this study was that lipid map uniformity was significantly higher in the Sj\u00f6gren\u2019s group than in controls (136.64nm\u00b2 vs. 62.70nm\u00b2, respectively), reflecting a more heterogeneous lipid distribution. The researchers explained in their paper that this \u201cmay suggest the presence of meibomian gland dysfunction amongst those with Sj\u00f6gren\u2019s Syndrome.\u201d Moreover, these patients had a higher prevalence of lipid-related dry eye disease, \u201cunderscoring the role the lipid layer plays in the pathophysiology of dry eye in this population.\u201d<\/p>\n

In contrast, other mean TFI measurements were not significantly different between groups: muco-aqueous layer thickness was 3701.39nm in the Sj\u00f6gren\u2019s group vs. 3384.80nm in controls; lipid layer thickness was 72.08nm vs. 54.31nm; interblink interval was 11.63s vs. 7.33s; and lipid breakup time was 5.36s vs. 3.75s. These findings, the authors wrote, \u201cfurther support the notion that lipid layer dysfunction may be more prominent in Sj\u00f6gren\u2019s Syndrome-related dry eye and that the lipid component of the tear film should be the focus of future research and therapeutic interventions\u201d for the condition.<\/p>\n

Moreover, the authors noted that tear film abnormalities captured by the TFI correlated with clinical findings, demonstrating the device\u2019s potential \u201cas a diagnostic and monitoring tool for assessing tear film function.\u201d The team observed a strong positive correlation between Schirmer\u2019s score and muco-aqueous layer thinning, \u201csuggesting a connection between aqueous production and tear film thickness,\u201d which they say \u201ccorroborates previous research utilizing the TFI.\u201d<\/p>\n

That said, the findings should be interpreted with caution. The Tear Film Imager is an investigational tool, and its clinical role remains to be established. This was also a small, single-center pilot study with only 15 patients in each group, so the results should be considered preliminary. Larger studies will be needed to confirm whether the device can reliably inform routine clinical care and whether the observed lipid-layer abnormalities translate into meaningful changes in diagnosis or treatment.<\/p>\n

Overall, this study reinforces that Sj\u00f6gren\u2019s dry eye is not just about aqueous deficiency. Lipid layer instability may be a major contributor, so meibomian gland evaluation and lipid-targeted therapies may deserve greater attention. The authors argued that future studies \u201ccan continue this research by expanding the patient population and categorizing patients based on their systemic disease and ocular findings, further advancing our understanding of SS-related DED and its management.\u201d<\/p>\n
