Nrog Goldmann lub " kev sib hloov " perimetry , ib tug kawm perimetrist txav lub stimulus; kev txhawb nqa qhov ci ci tau tuav tas li. Limits ntawm thaj chaw pom kev yog mapped rau lub teeb ntawm qhov sib txawv qhov ntau thiab tsawg thiab brightness. Feem ntau siv ib qho kev ntsuas nruab nrab 30 ° ntawm thaj chaw pom kev siv daim phiaj rau qib sib nrug rau qib 6.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog Goldmann perimetry?

Goldmann qhov muag kuaj yog dab tsi?
Cov Goldmann perimeter yog lub hollow dawb kheej kheej lub tais tso rau qhov chaw nyob deb ntawm tus neeg mob. Cov Goldmann txoj kev muaj peev xwm xeem tag nrho cov ntau ntawm peripheral pom kev , thiab tau siv rau xyoo los ua raws pom kev kev hloov hauv cov neeg mob glaucoma. Txawm li cas los xij, tam sim no automated perimetry yog siv ntau dua.
