Osmolaridad de la película lagrimal y test de Schirmer en el diagnóstico de Queratoconjuntivitis seca en perros (Canis lupus familiaris) en relación a su condición sexual”

Abstract

Keratoconjunctivitis sicca is one of the most common eyeball diseases in dogs, caused by inadequate tear production, limiting its quality and favouring vision loss. The objective of this research was to determine the relationship of keratoconjunctivitis sicca in dogs according to their sex and sexual condition, through the relationship of tear production and tear quality. 48 dogs between 1 and 5 years old were used, divided into 2 groups according to their sex (male / female) and these in subgroups by their sexual condition (intact / neutered). For the diagnosis, the Schirmer 1 Test was used for the measurement of tear quantity and the Osmolarity for the determination of tear quality. In the experimental design, an ANOVA was used to determine the homogeneity of variances and ranges were established according to severity for the two diagnostic methods. Categorical relationships were used using contingency tables and the Chi-square test to establish the presence of significant differences. Concluding that Schirmer levels between intact and neutered dogs without regard to sex (18.93 mm / min ± 5.46) did not show a significant difference (p <0.05), while for osmolarity between intact and neutered dogs (325.75 ± 23.01 mOsm / L) they presented significant differences (p> 0.05); and it was determined that, according to sex, males presented variation in osmolarity levels compared to intact (333.92 ± 4.71) and neutered (317.56 ± 4.14), and it was shown that in relation to tear quality, with the Schirmer Test 1 it presented no significance.
