OCULAR SIGNS IN 4 DOGS WITH HYPERTENSION

Four dogs suddenly developed visual problems associated with retinal d etachment and haemorrhage. They all had a high arterial blood pressure measured with a Doppler ultrasonic blood pressure monitor, Two of the dogs showed evidence of cardiac hypertrophy and one had hypercholeste rolaemia; in three of them there was no conclusive evidence of underly ing systemic disease, The condition was treated and assessed over a pe riod of 12 months. In the absence of any findings suggesting the prese nce of underlying systemic disease, it is possible that the ocular cha nges were the result of primary hypertension, although not every possi ble cause of secondary hypertension could be excluded.
