Association of macular pigment optical density with plasma macular carotenoids levels and serum lipids in South Indian healthy volunteers and patients with early age-related macular degeneration.

The objective of the present study was to investigate the relationship between macular pigment optical density (MPOD) and plasma carotenoids [(L) and (Z)] and serum lipids in South Indian young healthy volunteers and patients with early age-related macular degeneration (AMD). Two hundred and fourteen ( = 214) study participants (Healthy control group () = 178; Early AMD group () = 36) were enrolled after getting their written informed consent. The MPOD of the study participants was assessed using MPS II (Electron Technology, UK) after completing their routine ocular examination.
