Methods Retinal IBS of 120 healthy adults,40 hypertensive and 40 diabetic patients was analyzed by HP Sonos 5500. Results IBS% of retina increased with age, and it had positive correlation with age(r= 0.82 ). IBS% of hypertensive group was higher than that of healthy adult group(P 0.05 ). Conclusions IBS% of healthy adults′ retina increases with age; the retinal IBS% of the hypertensive and the diabetic patients are higher than that of the healthy adults.
