초록

목적: 발효자색고구마와 블루베리(blueberry)에서 추출한 안토시아닌의 시력보호 및 VDT 증후군 개선효과를 알아보고자 연구하였다. 방법: 실험은 안과질환 및 전신질환이 없고, 굴절이상이 -4.00 D 이상인 19~21세 남 여 20명을 대상으로 실시하였다. 40 mg의 발효자색고구마 및 블루베리 추출 안토시아닌과 대조군으로 위약을 각각 복용, 2시간 후에 근업(VDT)을 2시간 동안 실시하였다. 시력검사는 안토시아닌을 복용하기 전과 2시간 근업 후 각각 타각적 굴절검사 방법으로 측정하였다. 근업 2시간 후 VDT 증후군으로 두통, 안통 및 안정피로, 목, 어깨, 허리 등의 자각증상의 정도를 심함, 보통, 약간, 없음 등으로 구분하여 문진하였다. 결과: 2시간동안 VDT 작업 후 시력보호 효과는 우위안에 대한 굴절 값은 발효 자색고구마 추출 안토시아닌에서는 $0.031{\pm}0.21$ D, 블루베리 추출 안토시아닌에서는 $0.006{\pm}0.32$ D 만큼 근시도가 감소하였고, 위약에서는 $0.144{\pm}0.28$ D(t=2.27, p=0.03) 만큼 유의하게 근시도가 증가하였다. 결론: 발효자색고구마 추출 안토시아닌이 근업 후 굴절이상 값의 증가를 억제하고, 비우위안보다 우위 안에서 시력을 보호하는 것으로 생각된다.

Purpose: The purpose of this study was to research any effect on vision protecting or decreasing VDT syndrome of extracted anthocyanine from fermented purple sweet potato and blueberry. Methods: Subjects were aged 19-20 years old who do not have ophthalmic and systemic diseases and over -N4.00 D of refraction error. 40 mg of extracted anthocyanine from fermented purple sweet potato, from blueberry, and control group, placebo were dosed at separate try. After 2 hours later, subjects were directed perform visual display terminal (VDT) work for 2 hours. Objective refractive error was measured before dosing anthocyanine and after VDT work for 2 hours. Degree of head ache, eye pain and strain and subjective symptoms of neck, shoulder and waist was also examined through interviews by dividing its degree into severe, moderate, slight or none. Results: After 2 hours VDT work, vision protection effect in terms of refractive error for dominant eye was decreased by $0.031{\pm}0.21$ D in the group of extracted anthocyanine from fermented purple sweet potato, $0.006{\pm}0.32$ D in the group of extracted anthocyanine from blueberry. However, there was significantly myopic progression in the placebo group by $0.144{\pm}0.28$ D (t=2.27, p=0.03). Conclusions: It is considered that extracted anthocyanine from fermented purple sweet potato inhibits increase of refraction anomalies of dominant eye rather than non-dominant eye after VDT work.
