Two hundreds and seventy-five hypertensive patients were studied to evaluate age-associated effects of hypertension and blood total cholesterol on hypertensive retinopathy. One hundred and sixty cases didn't have retinopathy and 115 cases had
retinopathy. Below the age of 50, blood total cholestrol in hypertensives with retinopathy(group 1) was significantly higher than that in hypertensives without retinopathy(group 2) (man 236±31.9mg/dl versus mean 211±38.9mg/dl, p<0.001). Over
the
ate
of 50, blood total cholesterol was no significant difference between hypertensives with retinopathy (group 3) and hypertensives without retinopathy(group 4) (227.4±45.4mg/dl versus 227.5±40.7mg/dl). Below the age of 50, the ratio of moderate
and
severe hypertensives to mild hypertensives was 3.43 in group 1, while 0.65 in group 2, Over the age of 50, the ratio of moderate and severe hypertensives to mild hypertensives was 2.11 in group 3. Hile 1.25 in group 4.
Thus, below the age of 50, both hypercholesterolemia and hypertension may be important risk fators for retinopathy, and over the age of 50, hypertension may be more important than hypercholesterolemia.
