Abstract
Purpose :
To determine the effect of flicker on the optic nerve head (ONH) blood flow using laser speckle flowgraphy (LSFG), the study of which has not been undertaken previously.
Methods :
Ten eyes of 10 healthy subjects (6 women, 4 men; mean age, 54.6 ± 10.0 years) participated in this study to assess the effect of flicker stimulation on the ONH blood flow using LSFG. The mean blur rate in the ONH tissue area (MT) was measured using LSFG and compared before and after flicker stimulation.
Results :
The MT values before and after flicker stimulation were 15.6 ± 4.4 and 15.8 ± 4.2, respectively. The difference between the two did not reach significance.
Conclusions :
Our results suggested that there was no significant effect of flicker stimulation on the ONH blood flow assessed by LSFG.
