| Abstract;Purpose: The effect of stellate ganglion block(SGB) on human retinal blood flow was evaluated. Methods: We measured the diameter of the retinal artery and vein, and retinal venous flow rate by laser speckle retinal blood flow meter simultaneously in 11 eyes of 11 normal volunteers. Results: The reliable data from 9 eyes of 9 person were used for analysis. SGB did not change the blood pressure, heart rate, retinal arterial diameter, or venous diameter. However SGB increased retinal blood velocity significantly from 9.9.+-.1.6(mean.+-.standard deviation)mm/s to 11.1.+-.1.5mm/s(p<0.01). Intraocular pressure decreased from 12.3.+-.2.1(mean.+-.standard deviation)mmHg to 9.4.+-.2.2mmHg after SGB(p<0.01). There was no relationship between the change of ocular perfusion pressure and that of retinal venous blood velocity. Conclusion: SGB increased the retinal venous blood velocity without changing the retinal vessel diameter. (author abst.) |
