Abstract
Hypertension is a common disease in the general population especially in the middle and old ages. Hypertensive retinopathy is the clinical manifestation of systemic hypertension on the retinal vasculature and it presents the pathological effects of hypertension on the end-organs of the body namely the heart, kidney and brain. The appearance of arteriolosclerotic retinopathy denotes serious prognosis, since it results from a decompensated state of the retinal circulation. It is the manifestation of severe and wide spread retinal ischaemia resulting from the defective peripheral retinal circulation.The aim of this work is to determine the prevalence of retinopathy in patients with arterial hypertension and to identify the possible risk factors for the development of hypertensive retinopathy in patients with arterial hypertension and to evaluate the relationship between hypertensive retinopathy and level of arterial blood pressure, degree of control, duration and ferquency of complications of hypertension. One hundred and sixty patients with arterial hypertension were collected from the opthalmic out-patients chinic and some are referred from the general medical clinics and in-patients departments of Menoufia University Hospital and Shebin EL-Kom Teaching Hospital. All patients were subjected for full clinical evaluation, full ocular examination with fundus fluorescein angiography for some patients and laboratory investigations including fasting blood sugar, blood urea and serum creatinine. In this study prevlence of retinopathy in patients with arterial hypertension was 72% and 28% of cases showed normal fundus. 37.5% of cases showed hypertensive retinopathy and 28.0% cases showed arteriolosclerotic retinopathy. We recommed fundus examination for all hypertensive patients and those with impaired renal function. We also recommed follow up of those cases with fluorescein angiography to help the evaluation of the efficacy of antihypertensive therapy.
