Diseases of the eye and ear in dogs
Plocová, Markéta ; Fiala Šebková, Naděžda (advisor) ; Chmelíková, Eva (referee)
The work deals with the description of selected diseases of the eye and ear. In order to better understand the different diseases and disorders caused by them, there is first described the anatomy and physiology of the competent organs of vision and hearing, and the location of their centers in the brain. Some breeds, due to their anatomical and genetic foundation have predisposition to certain diseases or disorders. Selected diseases of vision and hearing are described in view of anatomical and physiological eventually. Part of the description of diseases is also an overview of the clinical signs and symptoms. Some of selected diseases are genetic and can be inherited from generation to generation. For these heritable diseases are mentioned the possible candidate genes and their localization. Next I explain the congenital diseases that may occur during prenatal or postnatal development. For each disease I present the table with breeds where the disease occurs.
Eye diseases mentioned in this work are largely genetic in origin, so there is described in detail the genetic basis of the disease with a potential name of the candidate gene, the mutation and its localization. I deal with the diseases of the Primary Lens Luxation (PLL), Canine Multifocal Retinopathy (CMR), Multifocal Retinal Dysplasia (MRD), Collie Eye Anomaly (CEA), Dry eye syndrome and curly hair (CKCSID), Glaucoma, Progressive Retinal Atrophy (PRA) . For these hereditary diseases, it is important for breeders to eliminate their occurrence with the consistent breeding work.
The most common diseases of the ear are called otities, ie. ear infections. These infections can lead to damage and finally to the complete loss of hearing. As a separate chapter I mention hearing disorder in Dalmatians, which is associated to the coat color. Next I deal with the neurological symptoms of ear disease, complication associated with total canal ablation and bulla osteotomy, pathological changes in congenital ear disorder MPS (Mucopolysaccharidosis), disorders of the inner ear and the vestibular system.
Finally, it should be noted that thanks to the latest findings of diseases, they are better described and it is achieved better recognition of diseases and their causes, but their prevention is dependent on the origin of the disease. For diseases obtained it is important for the dogs to ensure the welfare conditions, while for hereditary diseases it is necessary the negative selection in the respective breeding of the affected breed.
