Increased peripapillary choroidal blood flow velocity in peripapillary pachychoroid syndrome: Three case reports with referential observations in central serous chorioretinopathy

These findings suggest elevated choroidal blood flow velocity at the lesion site in PPS, as reflected by a higher MBR in the temporal peripapillary region compared to the macula. This distinct MBR distribution may serve as a valuable diagnostic marker for PPS.
