Standardization of the values of the "Schirmer Tear Test" modificated and of the "Schiötz Tonometry Indentation" from dogs of the region of Jaboticabal - SP – Brazil

Abstract

The keratoconjutivitis "sicca” and the glaucoma could he diagnosticated easily through the “Schirmer Tear and Schiötz Tonometry" respectively. To reach these objectives it's important to know the intrinsic values of each geographic region, because they are affected by environmental changes. Fifty adult dogs were studied, with or without breed, healthy, at the Ophthalmology Service of the Veterinary Hospital UNESP - Jaboticabal. For the "Schirmer Test" the technic was based on the application of a filter paper ribbon (Melitta^R) in the inferior conjunctival sac for 1 minute. For the "Schiötz Test" the technique included the appropriate contention and colocation of the Schiötz equipment upon the center of the cornea with a previous anesthesia. The results showed median values of 17,01 mm ± 4.28 mm for the "Schirmer Tear Test" and 29,15 mmHg ±4,60 for the "Schiötz Tonometry”.
