• To discuss the clinical implications and future directions of canine tear proteomics.

Main Methods:

• Comprehensive literature review of canine tear proteomics studies.
• Analysis of tear film composition, study designs, and technological advancements.
• Identification and discussion of key tear proteins and their alterations.

Main Results:

• Tear proteomics reveals disease-specific protein profiles in canine tears.
• Identified biomarkers are associated with various ocular and non-ocular canine diseases.
• Technological advancements are enhancing the scope and accuracy of tear proteomic analysis.

Conclusions:

• Canine tear proteomics is a valuable tool for veterinary ophthalmology.
• It facilitates early disease detection, diagnosis, and monitoring of treatment outcomes.
