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

Abstract

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.
