Abstract

Objectives: The purpose of this study was to examine the correlation between exposure to acetone and isopropyl alcohol (IPA) and the acquisition dyschromatopsia. Methods: A study was performed on exposure group of 116 people exposed to and a group of 36 people not exposed to organic solvents were selected and examined. Their smoking and alcohol habits, symptoms, and exposure history were surveyed through questionnaires and interviews. Then dyschromatopsia was evaluated with the Lanthony D-15 d test in a room with standardized intensity of illumination. Results: The statistical prevalence of dyschromatopsia was significantly higher in the exposed group (30.2%) compared to that found in the control group (19.4%). Out of the 116 subjects in the exposed group, 30 people had acquired dyschromatopsia (25.86%). The variables affecting the color confusion index, such as age, exposure, and the duration of exposure, were statistically significant variables. Conclusions: he prevalence of dyschromatopsia was found to be not significantly higher in the group with exposure to organic solvents compared to that found in the control group. In addition, a statistically significant correlation was found between exposure to organic solvents and the color confusion index.

목적: 아세톤 및 이소프로필알콜(IPA)에 혼합 노출되는 근로자를 대상으로 노출여부와 후천성 색각이상간에 연관성을 조사하기 위해 본 연구를 실시하였다. 방법: 일개 지역 아세톤 및 IPA 노출 근로자들 가운데 노출군 116명과 유기화합물에 노출되지 않는 비노출군 36명을 대상으로 조사하였다. 설문지 및 면담을 통해 흡연유무, 음주유무, 과거력 및 증상유무와 노출력을 조사하고, 조도가 표준화된 방에서 Lanthony D-15d검사를 이용하여 색각이상을 평가였다. 결과: 색각이상의 유병률은 노출군(30.2%), 비노출군 (19.4%)으로 차이가 있었으나 통계적으로 유의하지 않았으며, 유기화합물 노출군 116명 가운데 후천적 색각이상인 청황색색각이상자가 30명(25.86%)이었다. 색혼란지수에 영향을 줄 수 있는 변수중 노출유무가 통계적으로 유의한 변수였다. 결론: 유기화합물 노출여부와 색혼란지수 간에 통계적으로 유의한 연관성을 보이고, 유기화합물 노출군에서 색각이상의 유병률이 비노출군보다 높았으나 유의하지 않았다. 정량적인 평가가 색각검사를 이용한 조기선별검사에 활용에 도움이 될 것으로 판단된다.
