Mathematical verification of summary formula in retinal vessel diameter measurement

our previous study found the retinal vessel diameter measurement using summary formula has no significant difference for the multiple retinal images of the same person, while the individual vessel measures show the significant difference. It was speculated that the revised formula summariz...
