Abstract:
Reduction of LDL C levels and cholesterol level in blood plasma. According to the study of statins, it may result in decreased of Macular Pigment Optical Density levels. Studies have reported that taking statins has an inhibitory effect on HMG-CoA reductase activity at a period of 13-18 months, which increases the risk of Aged-related Macular Degeneration (AMD) disease.
Therefore, this study aimed to study the effect of Macular Pigment Optical Density on patients who took simvastatin 10 mg for 6-12 month in the Thai population. This research is a cross-sectional analytical study. By studying the Thai population, both male and female age between 35-55 years, 42 people, divided into 2 groups. The normal subjects and the taking simvastatin 10 mg for 6-12 months groups, using questionnaires and measure the Macular Pigment Optical Density levels with the Macular Pigment Screener II (MPS II) for both group. Every participant must sign a consent to participate in the research.
The result of this study found that the comparing the statistical data using the t-test method. The result showed no difference. (p = 0.284) In those with the taking simvastatin 10 mg for 6-12 months groups, who were not associated with MPOD levels. Period of taking simvastatin 10 mg for 6-12 month were not the relationship between duration of medication and MPOD levels.
