[Influence of long term occupational exposure to solvents on colour vision].
BACKGROUND
The study was designed to determine the influence of chronic occupational exposition of organic solvent mixtures on colour vision of car painters.


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.


CONCLUSIONS
The impaired colour vision may also be an important indicator of neuro-ophthalmological effects after long-term occupational exposure to organic solvents.
