Animals Studied: Three research dogs diagnosed with spontaneous KCS.

Procedures: Each dog was treated for three days, three times a day (TID) in both eyes (OU) with ES, followed by three days of treatment with eq-IRAP TID OU, followed by three days treatment with ca-IRAP TID OU. Clinical parameters (discharge, conjunctival hyperemia, chemosis) were scored on the last treatment day for each serum type. Schirmer tear test (STT) was measured throughout the study. The three different serum types were analyzed with ELISA kits for the concentration of equine interleukin-1 receptor antagonist (eq-IL-1Ra), and ca-IL-1Ra.

Results: All three serum types were well tolerated in the three dogs. Subjectively, dogs treated with ca-IRAP showed improved clinical parameters such as decreased conjunctival hyperemia. Objectively, no differences in STT were seen between the groups (P > 0.05). The highest concentration of IRAP was found in ca-IRAP analyzed for ca-IL-1Ra (299.7 pg/mL).

Conclusion: Topical ca-IRAP was noted to have the most significant clinical effect on evaluated parameters. Future long-term studies are needed to confirm the potential anti-inflammatory effect of topical ca-IRAP
