Systemic arterial hypertension is a condition characterized by elevated systolic blood pressure values above 160 mmHg, predominantly affecting cats older than 9 years. Hyperthyroidism, chronic kidney disease, hyperaldosteronism, and pheochromocytoma are the most common causes of elevated blood pressure in cats. Regardless of etiology, Hypertension causes target organ damage that involves kidneys, heart and eyes. We analyzed clinical data in a retrospective study in 19 cats that were treated during a period of 16 months. Initially, cats underwent ophthalmological examination with fundoscopy to determine the degree of developed retinopathy. Afterwards, they were referred for further internal medical evaluation with an emphasis on measuring systemic blood pressure. In the case of confirmed systemic hypertension, antihypertensive therapy was prescribed, along with ongoing ophthalmological monitoring of retinal changes. The mean value of initially measured systolic blood pressure was 247,6 mmHg. Cats aged 16 years were most commonly admitted. Blindness was the most noticeably manifestation of the disease that predominated mostly in female cats. Vision recovery was observed in almost one-third of blind cats, and a high degree of hypertensive retinopathy was confirmed in all of them.
