AIM:Toassessthequantitativeassociationbetweenanisometropiamagnitude(AM)andthelossesofresolutionandcontrastsensitivity;andtoexemplifyhowthefunctionoffusionandstereopsisvarywithAMinpreviouslyuntreatedanisometropicamblyopia.METHODS:Atotalof57patientswithpreviouslyuntreatedanisometropicamblyopiawithoutstrabismus(range:8-35years),weremeasuredrefractiveerror,bestcorrectedvisualacuity(BCVA),fusionandstereopsis,and48patientshavecompletedcontrastsensitivityfunctiontest.AMwasdeterminedbydioptricvectoradditionmodel,andtheamblyopiadepthwasdeterminedbythedifferenceofBCVAinlogMARunitsbetweentheamblyopicandfelloweyes.RESULTS:AMwassignificantlycorrelatedwithbothamblyopiadepth(PearsonR=0.728,P<0.001)andtheinter-oculardifferenceoftheareaunderthelogcontrastsensitivityfunction(AULCSF)(R=0.505,P<0.001).Depthofamblyopiaandtheinter-oculardifferenceofAULCSFwasalsosignificantlycorrelated(R=0.761,P<0.001).Themoreseverityofamblyopia,thepoorerlevelsofcontrastsensitivity.MostpureanisometropeswithAMwaslessthan3.0Dretainfusionandsomestereopsis,butwhenAMweremorethan3.0D,especiallyfortheanisometropeswhoseAMwasmorethan6.0D,fusionandstereopsisfunctionwereseriouslyimpaired.CONCLUSION:Inthepatientswithpreviouslyuntreatedanisometropicamblyopia,higherdegreeofanisometropiaissignificantlyassociatedwithdeeperamblyopia,worsecontrastsensitivity,fusionandstereopsisfunctions.
