PURPOSE
To compare macular pigment optical density using two different heterochromatic flicker photometers.
METHODS
We measured macular pigment optical density in 121 healthy subjects using heterochromatic flicker photometry.
RESULTS
The mean (+/-SD) macular pigment optical density measured using the Maculometer was 0.394 (+/-0.170), and that using the Densitometer was 0.395 (+/-0.189). The difference in measurements on each instrument was influenced by age and macular pigment levels.
CONCLUSIONS
On average, there is no difference in measurements provided by these two instruments. The Maculometer tends to underestimate macular pigment in older subjects and/or those with higher macular pigment compared with the Densitometer.
目的
使用两种不同的异色闪烁光度计比较黄斑色素光密度。
方法
我们使用异色闪烁光度法测量了121名健康受试者的黄斑色素光密度。
结果
使用黄斑计测量的平均（±标准差）黄斑色素光密度为0.394（±0.170），使用密度计测量的为0.395（±0.189）。每种仪器测量结果的差异受年龄和黄斑色素水平影响。
结论
平均而言，这两种仪器提供的测量结果没有差异。与密度计相比，黄斑计往往会低估老年受试者和/或黄斑色素较高者的黄斑色素。
