Kinetic　visual　field　refers　to　the　visual　range　in　which　a　moving　target　can　be　seen.　The　reaction　time　in　traditional　Kinetic　Perimetry　was　the　time　from　the　target　was　identified　to　the　subject　responded,　without　taking　into　account　individual　simple　reaction　time　(SRT).　This　is　problematic　in　that　it　mixes　the　evaluations　of　human　visual　performance　with　behavior　performance.　We　redefined　kinetic　visual　field　by　analyzed　the　components　of　the　RT,　and　then　measured　SRT　and　kinetic　visual　field　of　six　normal　subjects,　using　a　modified　Goldman　kinetic　perimeter.　The　results　showed　that　the　newly　defined　kinetic　visual　field　was　wider　than　traditional　defined,　because　the　newly　defined　kinetic　visual　field　without　including　SRT.　Thus,　Kinetic　Perimetry　using　the　newly　defined　method　eliminates　individual　SRT　differences　to　produce　what　we　believe　to　be　a　more　accurate　evaluation　indicator　of　human　visual　functions.　©　2011　Springer-Verlag.
