Representative images of the chorioretinal blood flow taken by a LSFG instrument with a SBR. A) Before TES. Squares were positioned in three different areas: the rim of the optic disc flanked by two branched vessels crossing the margin of optic disc. This area was selected so that there were no blood vessels. The other two areas were a point midway between the optic disc and macula and the macula area. The macula area was identified by the region without retinal vessels. B) Twenty-four hours after TES. The averaged SBR values within the square for each measurement are indicated below the square. The color map of chorioretinal blood flow shows an increase of blood flow after TES. In all areas, the chorioretinal blood flow was increased, especially in the midway point.
