Correlations among macular pigment optical density, central macular thickness, and body mass index

AIM: To determine the relationship among the macular pigment optical density (MPOD), central macular thickness (CMT) and body mass index (BMI). METHODS: This is a comparative cross-sectional study performed in a single institution. Totally 210 volunteers who met the inclusion criteria were included in this study. The subject’s MPOD was measured using Macula Pigment Screener II (MPS II, by Electron Technology). CMT was measured with Spectral Domain Cirrus Optical Coherence Tomography (OCT), Cirrus (Model 4000, Carl Zeiss Meditec). The information of both MPOD and OCT from both eyes were recorded. The data was analysed using Microsoft® Excel, SPSS, and R (version 3.2.1; R Core Team 2015). RESULTS: There was significant positive correlation between MPOD and CMT (r=0.42, P
