AIM:Tomeasurecentralcornealthickness(CCT)andpre-cornealtearfilmthicknessusingtheGalileidualScheimpfluganalyzer(GSA)inNewZealandWhiterabbits.METHODS:TennormalNewZealandWhiterabbits(20eyes)wereincludedinthisstudy.Withtheassistanceof0.1%fluorescein,thepre-cornealtearfilmcanbewellvisualized.BotheyesofeachrabbitwerescannedoncewiththeGSApre-andpost-instillationof1μL0.1%fluorescein.ThedifferencebetweenthetwomeasurementsofCCT(4-mmdiameter)wasrecordedasthepachymetricvaluesofthecentraltearfilm.RESULTS:TheCCTofpre-andpost-instillationwas388.8±9.5μmand407.0±10.5μm,respectively.Afterapairedt-testanalysis,thecentralpre-cornealtearfilmthicknessof4mmdiameterwas18.2±5.31μmwitha95%confidenceintervalof(15.7,20.6)μm(P<0.001).CONCLUSION:GSAcanbeusedtomeasureCCTandanalyzecentraltearfilmthicknessofrabbitswiththehelpoffluorescein.
