Tear clearance rate in dogs: Measurement using anterior segment optical coherence tomography.

ABSTRACT:

Objective

The tear clearance rate (TCR), determined using anterior segment optical coherence tomography (AS-OCT) images, and its correlation with ocular surface parameters, including blink rate, Schirmer tear test-1 (STT-1) and tear film breakup time (TFBUT), were evaluated.

Animals studied

Left eyes of 20 client-owned dogs with no ocular disease symptoms.

Procedures

The tear meniscus height (TMH) was evaluated using AS-OCT images before the instillation of 5 μL saline (TMH_base ), immediately post-instillation (TMH₀ ), 30-s post-instillation (TMH_0.5 ) and at 1 min intervals for 5 min post-instillation (TMH₁ , TMH₂ , TMH₃ , TMH₄ and TMH₅ ). The TCR was calculated using the formula [
