Abstract

Purpose: : To evaluate achromatic and chromatic vision of workers chronically exposed to organic solvents using psychophysical methods.

Methods: : Twenty nine gas station workers chronically exposed to organic solvents (mean labor time: 52.3±64.1 months) were evaluated with the following visual psychophysical tests: Farnsworth-Munsell 100 (FM-100) (n = 26), Mollon-Reffin (MR; n = 17), spatial and temporal contrast sensitivities (n = 25), and static threshold visual perimetry (STVP; n = 21).

Results: : FM-100 test.

Conclusions: : Color vision losses were more frequent, followed by losses in spatial and temporal contrast sensitivity. The visual field sensitivity was impaired at 10 and 30o of eccentricity.

Keywords: color vision • contrast sensitivity • low vision
