T Cells in Ocular Surface Disease
From Surveillance to Dysregulation.
Course Overview
The adaptive immune system plays a central and often underappreciated role in the pathogenesis of ocular surface disease. This Masterclass provides a rigorous exploration of T cell biology as it applies to the ocular surface — from normal immunosurveillance to the dysregulated inflammatory cascades that drive chronic disease. Clinicians who understand these mechanisms are better equipped to select immunomodulatory therapies rationally and to anticipate the clinical course of inflammatory ocular surface conditions.
Clinical Relevance
Dry eye disease, meibomian gland dysfunction, and related ocular surface conditions are increasingly understood as inflammatory disorders with adaptive immune components. The therapeutic agents used to manage these conditions — cyclosporine, lifitegrast, and others — target specific immunologic pathways. A working knowledge of T cell biology transforms these therapies from empiric choices into mechanistically informed decisions.

Learning Objectives
Upon successful completion of this educational experience, the clinician will be able to:
Describe the role of T lymphocytes in normal ocular surface immunosurveillance and homeostasis.
Explain the pathogenic mechanisms by which T cell dysregulation contributes to chronic ocular surface inflammation.
Identify the specific T cell subtypes and cytokine pathways implicated in dry eye disease and related conditions.
Connect immunologic mechanisms to the clinical rationale for immunomodulatory therapeutic choices.
Apply an immunologically informed framework to the clinical management of chronic ocular surface disease.
Course Modules
This educational experience is organized into the following modules. Content is subject to refinement prior to final release.
Foundations of Adaptive Immunity
T cell development, activation, and effector function — the immunologic vocabulary needed to understand ocular surface disease.
The Ocular Surface Immune Environment
Conjunctival-associated lymphoid tissue, antigen presentation, and the unique immunologic properties of the ocular surface.
T Cell Subtypes in Ocular Surface Disease
Th1, Th2, Th17, and regulatory T cells — their distinct roles in ocular surface homeostasis and disease pathogenesis.
Inflammatory Cascades and Clinical Correlates
From T cell activation to tissue damage — connecting the molecular events to the clinical signs and symptoms of ocular surface disease.
Therapeutic Implications
How immunomodulatory agents target T cell pathways — the mechanistic basis for cyclosporine, lifitegrast, and emerging therapies.
