Macular pigment optical density assessed by heterochromatic flicker photometry in eyes affected by primary epiretinal membrane

Purpose:

To compare macular pigment optical density (MPOD) in healthy eyes versus eyes affected by primary epiretinal membrane (ERM) in different stages and to assess the relation between MPOD and optical coherence tomography findings.

Methods:

Prospective cross-sectional study of 62 eyes of 62 patients affected by unilateral primary ERM. Contralateral healthy eyes from the same patients were used as a control group. Main outcome measures were MPOD, ERM stage, central foveal thickness (CFT), outer nuclear layer thickness (ONLT), integrity of outer retinal bands, and presence of central bouquet abnormalities.

Results:

In the study group, mean CFT was 444 ± 75 μm and mean ONLT was 245 ± 40 μm, whereas in the control group, mean CFT was 230 ± 21 μm and mean ONLT was 102 ± 14 μm (P
