Tear production as measured by Schirmer tear test-1 in dogs with atopic dermatitis.

ABSTRACT:

Objective

The objective was to measure tear production using Schirmer tear test-1 (STT-1) in dogs with atopic dermatitis, to evaluate for abnormal tear production.

Animals

We evaluated 47 client-owned dogs diagnosed with atopic dermatitis based on history, clinical signs, completion of an elimination diet trial, and fulfillment of at least 5 of Favrot's diagnostic criteria.

Procedure

Schirmer tear test-1 was conducted on each dog. Values < 15 mm/min were consistent with low tear production and suggestive of keratoconjunctivitis sicca. Values > 25 mm/min were consistent with epiphora due to excess lacrimation.

Results

Twenty-one of 47 atopic dogs had STT-1 values outside the normal range in at least 1 eye. Three had STT-1 values < 15 mm/min and 18 had STT-1 valu
