Abstract
Objective: To explore the effect of time exposure to flat screen electronic devices with LED 14 lighting and the Mediterranean diet on macular pigment optical density (MPOD). Methods: MPOD 15 was measured by heterochromatic flicker photometry in 164 eyes (47 of young women 20-31 years 16 and 35 adult women 42-70 years). Exclusion criteria: evidence of macular degeneration and eyes 17 with cataracts. Data on the use of electronic devices and Mediterranean diet adherence were col- 18 lected through a survey. Nonparametric analysis of variance and independent sample t-tests were 19 used to compare subjects. Results: Significant differences (p<0.01) were found in total time of expo- 20 sure to LEDs (hours per day) between both groups (9.31 ± 3.74 young women vs 6.33 ± 3.64 old 21 women). The MPOD values for the young and adult populations were significantly different: 0.38 ± 22 0.16 and 0.47 ± 0.15 (p<0.01), respectively. When comparing both groups for the same time of expo- 23 sure to LEDs, differences were obtained between MPOD values of both populations: For total expo- 24 sures greater than 6 hours per day, the MPOD values were lower in young women than in adult 25 ones (0.37 ± 0.14 vs 0.50 ± 0.14, p<0.01). On the other hand, a significantly higher adherence was 26 found in the old women in comparison with the young women (OW 9.23± 2.50 vs YW 7.70 ± 2.08, 27 p<0.01), with higher MPOD values, (OW (0.52 ± 0.14) vs (YW (0.34 ± 0.18). Conclusions: Higher 28 MPOD values are observed with decreasing exposure time to electronic devices with LED lighting 29 screens and high adherence to the Mediterranean diet.
