AIM:Toassesstherepeatabilityofmeasuringopticnervehead(ONH)parametersusingtheCirrusopticalcoherencetomography(OCT),aswellastoassesstheeffectofheadtiltonthesemeasurements.METHODS:Thirtyhealthyparticipantswithnoevidenceofglaucomawererecruitedforthestudy.Visualacuity,intraocularpressure,standardautomatedperimetryandocularexaminationwereperformedforeachparticipant.OneeyewasthenrandomlyselectedandscannedundilatedwiththeCirrusOCTin3positions(neutral,30°righttiltand30°lefttilt).RESULTS:Datacollectedfrom29eyeswereusedforanalysis.Onepatientwasomittedduetopoorscanquality.TherepeatabilityoftheONHparameterswasanalyzedusinganalysisofvariance,coefficientofvariation(COV)andintraclasscorrelationcoefficient(ICC).Analysisofvarianceshowednostatisticallysignificantdifferencebetween3scansinasingleposition.Therewasgoodagreementbetweenmeasurements(ICC0.919-0.996,COV1.94%-5.48%).Evenwiththepresenceofheadtilt,repeatedscansinthe3positionsshowedgoodagreementaswell(ICC0.888-0.996,COV2.04%-5.39%).CONCLUSION:SerialmeasurementsofONHparametersusingtheCirrusOCTarefoundtohavegoodrepeatability.TheONHparameterswithCirrusOCTalsomaintaingoodrepeatabilitydespiteheadtilt.
