ABSTRACT

Introduction: Although affecting an estimated 35% of the population, Dry Eye is not well understood by patients and the medical community. As a result, both in research and clinical settings, diagnostic and treatment protocols tend to be non-specific, ad hoc, and inadequate, with a narrow industry-driven focus. The purpose of this convening was to propose a research roadmap that orients Dry Eye researchers toward a comprehensive patient-centered approach to diagnosing and treating Dry Eye, Meibomian gland dysfunction (MGD), and related comorbidities with a goal of improving clinical outcomes for Dry Eye/MGD patients. Methods: Sixteen participants, including Dry Eye/MGD patients, caregivers, and patient advocates together with a group of experts in Dry Eye, MGD and other fields identified gaps in research on Dry Eye and MGD diagnostic and treatment approaches (age range 20-80; male to female ratio of 7:11; patients: 7). During a 2-day virtual convening, participants were assigned to topic-specific focus-group sessions to discuss and develop research questions pertaining to Dry Eye and MGD. The research questions were compiled into a proposed patient-centered roadmap for Dry Eye and MGD research. Two additional participants contributed to the proposed roadmap following the convening. Results: The focus groups identified over 80 patient-centered research questions important to patients and other stakeholders and compiled these into a proposed research roadmap. Conclusion: The convened stakeholders aim to establish a cohesive and comprehensive patient-centered approach to treating Dry Eye, Meibomian Gland Dysfunction, and comorbidities. The research roadmap will serve as a reference for researchers, educational institutions, clinicians, and others evaluating diagnostic and treatment protocols in Dry Eye and MGD.

ABSTRACT

Purpose: To demonstrate that the meibomian gland ductal basement membrane and basal epithelial cell layer are in continuity with and may derive from lid margin orifice-associated rete ridge epithelial/basement membrane structures (OARREBS) and to characterize changes in the distal duct microanatomy after meibomian gland probing (MGP) using in vivo confocal microscopy (IVCM). Patients and Methods: Pre/post-MGP IVCM examinations were performed on upper lids. Thirty-six identical glands from 20 lids of 16 patients (49.24 ±17.11 y/o with 13:3 F:M) were identified, analyzed, and compared to control cases. Statistical analyses were performed using ImageJ software and IBM SPSS version 27. All MGPs were performed within 12 weeks of the initial examination. Post-MGP follow-up exams occurred at 5.03 ±4.48 months. Results: Post-MGP images showed more superficially organized OARREBS with accelerated and more superficial basement membrane formation, and an average increase of 32.2%, 25.4%, 32.04%, 77.7%, and 81.3% in duct wall epithelial cell layers (DWECL) (p < 0.001, compared to control (CTC) p < 0.001), distal duct wall thickness (DWT) (p < 0.001, CTC p < 0.001), proximal DWT (p < 0.001, CTC p < 0.001), distal lumen area (p < 0.001, CTC p = 0.037), and proximal lumen area (p < 0.001, CTC p = 0.007), respectively. The increase in the distal DWT and lumen area correlated with the months of follow-up (p = 0.004 and p = 0.010, respectively). Immediate post-MGP imaging revealed the probe track confined to the ductal epithelial compartment. Conclusion: MGP appears to stimulate a proliferative epithelial response characterized by an accelerated more superficial formation of ductal basement membrane with increased DWECL as well as DWT and lumen area at two separate duct foci. These findings suggest activation of lid margin meibomian gland precursor cells and confirm that MGP stimulates an epithelial regenerative phenomenon, not a fibrotic one.
