    Dear Editor,

    We appreciate a response to our study from Dr Landers et al. They reported that five out of ten eyes with abnormal result of Frequency Doubling Perimetry (FDP) and normal result of Achromatic Automated Perimetry (AAP) showed abnormal result on AAP four years later.[1] It was our mistake that we referred their study as a cross-sectional study in our paper. We apologize to them that we should have referr...

    Detecting early visual field loss with Frequency Doubling Perimetry

    Dear Editor,

    We congratulate Kogure et al,[1] on a well designed longitudinal study, which confirms the suspicions of many earlier investigators, who conjectured that Frequency Doubling Perimetry (FDP) may be able to detect visual field loss earlier than Achromatic Automated Perimetry (AAP) based on cross-sectional data. In their text they refer to our longitudinal study[2] as a cross-sectional one and go on to s...
