  • Title: [Influence of long term occupational exposure to solvents on colour vision].
    Author: Böckelmann I, Lindner H, Peters B, Pfister EA.
    Journal: Ophthalmologe; 2003 Feb; 100(2):133-41. PubMed ID: 12589458.
    Abstract:
    BACKGROUND: The study was designed to determine the influence of chronic occupational exposition of organic solvent mixtures on colour vision of car painters. SUBJECTS AND METHODS: The 123 subjects (2 groups differing in organic solvents exposure and 1 control group) were examined using Ishihara-Panel, Lanthony Desaturated Panel D-15, Velhagen-Panel, and Tritan-Album. RESULTS: In the Velhagen-Panel 3% of the probands currently exposed to organic solvents, and 11% of formerly exposed probands developed a blue/yellow vision defect for the right eye. All control subjects perfectly finished this panel. In the Tritan-Album 3% of currently exposed subjects and 26% of formerly exposed painters expressed a blue/yellow vision defect for the right eye, but also 7% of controls showed anomalies. Similar results were found for both panels with the left eye. The CCI difference in the D-15 test was significant between all three groups. CONCLUSION: The impaired colour vision may also be an important indicator of neuro-ophthalmological effects after long-term occupational exposure to organic solvents.
