Abstract: The paper presents the study of Central visual analyzer eyes of 53 cats in the city of Perm, the Department of infectious diseases, PSATU for the period from 2016–2018 years. The considered Department of the organ of vision is one of the most significant objects due to the fact that it is the final link in the process of perception of animal information from the outside. After the natural death of the animal or its humane euthanasia due to incurable disease, the Central visual analyzer was extirpated, then the size of the organ was recorded, its shape, color and consistency, the presence of externally visible focal changes were determined. Then the cutting of the material was carried out, which assumed taking sufficient in quantity and quality to study the volume of tissue, different in structure and properties. Histological wiring of the material necessary for the study was performed. The obtained sections were painted according to standard methods and examined in a light microscope of Axioscop 40 with an eyepiece 10x, at magnifications of the lens 5x; 40x; 100x. The considered structures of the visual analyzer are an integral part of the General work on the study of this organ in the age aspect in cats. In foreign and domestic literature we have found only fragmentary data on the changes in the visual analyzer cats of advanced age. Mainly their description in the literature is associated with their underlying diseases. In the perspective of naturally occurring age-related changes, this issue has not been previously considered. In the future, we plan to compile an Atlas of pathomorphological changes in the visual analyzer of cats in the age aspect.
