    Evaluación de la electroretinografía para el diagnóstico de atrofia progresiva de la retina en pacientes caninos (Canis lupus familiaris) realizada con y sin anestesia

    Veterinary ophthalmology is most important today, through it is possible to study and learn about the ocular physiology of animals and improve their quality of life, especially when they develop eye problems, blindness that far from reducing mobility allows them to develop other sense organs such as smell and hearing. The objective of the present investigation was to evaluate electroretinography for the diagnosis of progressive retinal atrophy in canine patients (Canis lupus familiaris) with and without anesthesia, 40 dogs were evaluated at the MEDIPET Veterinary Hospital, in the Quito city, the results shows that: in the reading of the electroretinogram, 66.2% of the dogs present normal functionality, the detection of early progressive retinal atrophy (APRT) it was more efficient when anesthesia was used in the veterinary examination, in the same way to detect advanced progressive retinal atrophy (APRA) the requirement for anesthesia was evident. Regarding the suggestion of the use of anesthetic to more accurately identify the presence of APRT and APRA, it is evident that the incorporation of anesthesia prior to reading the electroretinogram improves the possibility of identifying abnormalities, both the Mc Nemar test and the binary logistic models date showed using classification tables for the right and left eyes that the use of anesthesia allows the detection of 70.10% and 70.70% of APRT and APRA.

    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”
    (2020-03-03) Mejía Freire, María Gabriela; Idrovo Ortiz, Jenny Zoraida
    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.
