어느 배경이 있는지는 모르겠습니다. 제약회사의 지원을 받거나 그런 내용에 대해서는요, 그런데 하버드 의대에서 비교 대조군 연구결과 루테인 12mg 과 비타민 A, 15000IU, 그리고 오메가 3등과 함께 섭취한 실험군과 그렇지 못한 대조군(placebo tablet)과의 시야 감소에는 확실히 차이가 있다고 나와있습니다. 특정 약을 언급하고 있어서 어느정도 신빈성이 있는지는 모르겠습니다만, 저도 오늘 찾다보니 찾게된 글입니다.. 참고정도로 해주세요~
Retinitis pigmentosa
In 2010, a study was published online in the Archives of Ophthalmology that offers new hope for the prevention of visual field loss in patients suffering from retinitis pigmentosa. In this study conducted by lead author Eliot Berson, M.D. (Berman-Gund Laboratory at Harvard Medical School), non-smoking patients aged 18-60 years with retinitis pigmentosa (RP) received either 12 mg of FloraGLO lutein or a placebo tablet daily. All patients received 15,000 IU/day of vitamin A and throughout the study period were advised to eat 1 to 2 servings of oily fish per week to increase their intake of long chain omega-3 polyunsaturated fatty acids. During the 4 years of supplementation, a decline in visual field area was apparent in all patients. However, a significantly lower decline was observed in the group supplemented with 12 mg/day lutein, compared to the placebo group. The authors estimated that the benefit of lutein supplementation on the long-term course of midperipheral visual field among RP patients also taking vitamin A and eating an oily fish diet would be 3 to 10 years of protection against further loss of sight. No adverse effects of lutein supplementation were noted during the 4 years of supplementation. Retinitis pigmentosa is the name of a group of inherited eye diseases which results in poor night vision in adolescence, and the loss of side (midperipheral and far peripheral) vision in adulthood with tunnel vision as the outcome. As this disease progresses, patients loose their central vision by 60 years of age. For this study, DSM Nutritional Products supplied the lutein tablets which contained FloraGLO Lutein and used the Actilease�, technology in order to increase the bioavailability of lutein.Actilease is a registered trademark of DSM.
