Background: Chronic kidney disease (CKD) has typically a non-immune mediated origin in cats and immune-complex glomerulonephritis (ICGN) is scarcely described. Aims of this study were to characterize ICGN by light and electron microscopy and identify associations with clinico-pathological findings. ...

Persistent pupillary membranes (PPMs) are embryonic residues of neural-crest origin. During the embryonic life, the pupillary membranes have the role of feeding the developing lens but they lose this function when the aqueous humour is produced. Normally, few weeks after birth, the pupillary...

A cat, thought to be 5 years old, and with reduced appetite and weight loss, was presented for dental cleaning and extractions. Bile duct origin hepatic carcinoma was diagnosed. The progression of iris degeneration, dental disease, histological renal lesions, spondylosis, and hepatobiliary...

This case report describes three different ocular diseases in captive felids that were detected at a single zoological institution. The first case is a non-metastatic multifocal iris melanoma in a 14-year-old snow leopard (Uncia uncia). Symptoms were brown discolorations of the physiologically...

Background: In human medicine, Urrets-Zavalia syndrome (UZS) is a well-recognized but uncommon postoperative complication characterized by a fixed dilated pupil, accompanied by iris atrophy and glaucoma. Although it was originally reported in 1963 after penetrating keratoplasty surgery for...

Chronic kidney disease (CKD) is prevalent in elderly cats. Frequently, a diagnosis is made in later stages of disease, by which time many renal lesions are irreversible. As such, little headway has been made in identifying an etiology and preventing this common disease. The aim of this study was to ...

Due to its strong vascularization, the eye can be a target organ of systemic diseases. The aim of this prospective study was to examine cats suffering from systemic diseases for acute, pathological, ophthalmological findings. Cats that were presented to the Clinic for Small Animals, Freie...

Background: Chronic kidney disease (CKD) is associated with morbidity and mortality in dogs. Plasma fibroblast growth factor-23 (FGF-23) concentration is an independent predictor of CKD progression and survival in cats and people with CKD. Objectives: To investigate the relationship among FGF-23,...

Cataract is a ophthalmopathy characterized by opacity in the lens, classified according to their etiology, occurrence age, location, aspect and stage of development. Its formation is associated with aggregation of lens proteins, increase in insoluble proteins, osmotic stress, dysfunction in...

Purpose: To investigate if retinal blood flow decreases with progression of the disease in Abyssinian cats with progressive retinal atrophy (PRA), to examine if the choroidal blood flow was affected by the disease, and to determine the uptake of glucose and formation of lactate in the outer retina. ...
