title: [Retinal circulation and ocular blood barrier in diabetic retinopathy].
abstract: Macular capillary blood flow velocity, the score of fluorescein angiography in posterior region and aqueous flare intensity were investigated in 38 diabetics (41 eyes) and 6 normal subjects (6 eyes) to clarify the relationship among retinal circulation, blood-retinal barrier and blood-aqueous barrier. Macular capillary blood flow velocity was measured by means of the blue field entoptic phenomenon, the score of fluorescein angiography was graded by the extent of edema in the posterior region, aqueous flare intensity was measured with a flare-cell meter. The results showed that the reduction of macular capillary blood flow is significantly associated with an increase in fluorescein angiography score and aqueous flare intensity via diabetic retinopathy (p less than 0.01).
