This video demonstrates a technique to induce chronic experimental autoimmune dry eye disease in rats. Upon injecting an antigen-adjuvant emulsion containing autoantigens and foreign antigens into a rat at predefined intervals, chronic eye inflammation is induced in the immunized rat by injecting the same antigens into the ocular surface tissues.

Without using anesthesia, subcutaneously inject the emulsion at the base of the rat tails. Then, on day 14 in a similar manner, inject 200 microliters of the same antigen and incomplete Freund's Adjuvant. On the same day, intraperitoneally inject 300 nanograms of pertussis toxin in 100 microliters of PBS.

This report describes a method to induce chronic experimental autoimmune dry eye in Lewis rats through immunization with an emulsion of rat lacrimal gland extract, ovalbumin, and complete Freund's adjuvant, followed by the injection of lacrimal gland extract and ovalbumin into the forniceal subconjunctiva and lacrimal glands six weeks later.

FAQs
Tear-film instability increases the ocular surface’s exposure and osmolarity, meaning the tear environment becomes more concentrated. These changes activate epithelial stress responses in corneal and conjunctival cells. The resulting cellular strain helps explain how an initial lubrication problem can progress to surface damage, worsening tear-film function and sustaining discomfort or visual disturbance.
Inflammation can create a self-reinforcing cycle. Tear-film disruption activates inflammatory pathways, and inflammation can damage corneal and conjunctival cells that help maintain the ocular surface. As epithelial integrity and tear function decline, the surface becomes more vulnerable to continued stress. This feedback pattern is why controlling harmful inflammation is a central research and treatment objective.
Barrier tissues are not passive coverings in this model. Corneal and conjunctival cells respond to increased surface exposure and osmolarity, while their damage can further impair tear function. Studying these epithelial responses alongside innate immune signaling helps researchers connect physical barrier disruption with inflammation, providing a framework for understanding ocular surface disease.
Chronic dry eye links several areas of immunology and infection research at one anatomical site. Investigators can examine how barrier tissues, innate immune signaling, microbial communities, and inflammation interact when the tear environment is disturbed. This makes the condition useful for studying coordinated host-surface responses rather than treating inflammation or microbes as isolated factors.
A mechanism-focused study can follow a connected sequence: assess tear production or evaporation, examine tear-film stability, consider surface exposure and osmolarity, and then evaluate epithelial stress, inflammatory pathways, and microbial-community interactions. Organizing observations this way helps distinguish initiating conditions from downstream consequences and clarifies which stage a diagnostic or therapeutic strategy addresses.
Research findings can guide interventions toward three complementary goals: restoring lubrication, protecting epithelial integrity, and controlling harmful inflammation. Focusing on only one outcome may leave the feedback between tear-film dysfunction and surface injury unresolved. Evaluating these goals together can help determine whether an approach improves the ocular environment, limits cellular damage, and supports more stable tear function.
