Relationships among Ocular Blood Flow Shown by Laser Speckle Flowgraphy, Retinal Arteriosclerotic Change, and Chorioretinal Circulation Time Obtained by Fluorescein Angiography

Table 8

Results of multiple regression analysis for factors independently contributing to the retinal circulation time ().

Explanatory variable	RT (early phase)		RT (late phase)
	Standard regression		Standard regression
RVO (+ = 1, − = 0)	0.31	0.0002	0.32	0.0001
MBR-V	−0.36	<0.0001	−0.26	0.001
Scheie classification (normal to group 3)			0.25	0.003
Men = 1, women = 0	0.14	0.08	0.19	0.02
Hypertension (+ = 1, − = 0)	0.08	0.31	0.02	0.81

Correlation coefficients: , ; , .
RT: retinal circulation time, RVO: retinal vein occlusion, and MBR: mean blur rate.
