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.
