Description:

ABSTRACTPurpose:Tocompare macular pigment optical density using twodifferent heterochromatic flicker photometers.Methods:Wemeasured macularpigment optical density in 121 healthy subjects using heterochromatic flickerphotometry.Results:The mean (±SD)macular pigment optical density mea-sured using the Maculometer was 0.394 (±0.170), and that using the Densito-meter was 0.395 (±0.189). The difference in measurements on each instrumentwas influenced by age and macular pigment levels.Conclusions:Onaverage,there is no difference in measurements provided by these two instruments. TheMaculometer tends to underestimate macular pigment in older subjects and/orthose with higher macular pigment compared with the Densitometer.
