BACKGROUND: Our aim is to compare retinal sensitivity measurements obtained on two microperimeters: the CenterVue MAIA and the Nidek @entity7454 . DESIGN: A prospective study was conducted in a private ophthalmology clinic. @entity1 : Seventeen individuals with a range of stable macular function were recruited as @entity1 . METHODS: Microperimetry in one eye with identical test strategy in both devices, with randomized testing order, is used. MAIN OUTCOME MEASURES: The main outcome measures include differences in @entity2915 ( @entity2915 ), @entity1166 ( @entity1166 ) and duration. Limits of agreement (LoA) in @entity2915 and pooled @entity1166 were calculated. Concordance in @entity1019 assessment was analysed by kappa (k) agreement of local defect classification (LDC), LoA in number of scotomatous loci detected and congruence in @entity1019 localization (CSL). RESULTS: Median (interquartile range) @entity2915 of the @entity7454 and MAIA was 13.3 (5.6-18.1) and 21.2 (14.5-27.0) dB, (P   <   0.05). Mean difference in @entity1166 was 7.3   dB (MAIA   >   @entity7454 ). Median (interquartile range) duration for the @entity7454 and MAIA was 10'28    (7'17   -11'53   ) and 8'46    (8'30   -9'06   ), (P   =   0.21). LoA for @entity2915 and pooled @entity1166 was 1.4 to 13.3   dB and -3.9 to 18.5   dB. There was moderate agreement between the devices for LDC (weighted k   =   0.55, P   <   0.05). LoA in number of scotomatous loci detected was -13 to 18. CSL varied from 0 to 100% and correlated strongly with increasing @entity1019 size. CONCLUSIONS: The large LoA and variation in @entity1019 mapping concordance suggest that the same microperimeter should be used for follow-up examination. We recommend caution in comparing results derived from different types of microperimeters.
