Descriptions
In order to investigate the relationship between retinal circulation and aqueous humor outflow, disk cupping or intraocular pressure (IOP) in patients with primary openangle glaucoma (POAG), we measured the coefficient of the facility of outflow (C value), cupping/disk ratio (C/D ratio) and IOP. And then, we calculated build-up time(BT), time constant of washout rate (TC) and mean circulation angiography. We studied two groups : Normal group was 12 eyes of 11 normal subjects, and POAG group was 10 eyes of 7 POAG patients. Moreover, we examined the effect of β-blocking instillation by 2% carteolol in POAG. The results ware as follows : 1) In arteries, Bt and TC in POAG group ware slightly, and significantly more prolonged than those in normal group, respectively (TC : POAG 40.24±23.99 vs Normal 24.79±14.61 sec
