Abstract
- After injection of See of 10% fluorescein sodium into the antecubital vein, the arm-to-retinal times of 22 normal adults were measured by watching through KOWA fundus camera (exciter filter: Fuji 18, barrier filter: Kodak Wratten 15G), and the retinal circulation times of 13 normal adults were measured with pictures of the serial fluorescein angiography by ZEISS fundus camera (exciter filter: Kodak Wratten 47A, barrier filter: Schott GG14). The normal ranges and the mean values of arm-to-retinal time and retinal circulation time are: 1. Arm-to-retina time; 9.0 sec. - 21.5 sec. (mean; 14.1 sec.). 2. Retinal circulation time; a. Early venous phase; 1.0 sec. - 5.0 sec. (mean; 2.6 sec.). b. Late venous phase; 4.5 sec. - 11.0 sec. (mean: 8.1 sec.).
