**5. Conclusions**

In conclusion, our study investigated the difference of MPOD and MP spatial distribution between POAG eyes and control eyes in the elderly in the frame of a population-based study. We found no significant difference between these two groups. The clinical relevance of the relationship between POAG and macular pigment warrants further studies.
