||Visual and ocular changes associated with exposure to two tertiary amines
||Jan. 2003, Vol.60, No.1, p.69-75. Illus. 11 ref.
||To determine if exposure to dimethylisopropanolamine (DMIPA) and dimethylaminoethanol (DMAE) in a label-printing plant was associated with visual disturbances or ocular changes, questionnaire surveys, eye examinations (visual acuity, contrast sensitivity, slit lamp biomicroscopy and pachymetry) and measurements of workplace airborne concentrations of DMIPA and DMAE were performed over a two-week period. 89% of line (high-speed printing) workers reported having experienced blurry vision while at work in the past 12 months, compared to 12.5% of prime (lower-speed printing) workers. The mean time weighted average concentrations of DMIPA, DMAE and total amines were significantly higher in the line division than in the prime division. Higher levels of total amines were associated with increased risk of reporting blurry vision, halo vision, and blue-gray vision. The prevalence of corneal opacity increased with increasing duration of exposure to total amines and with increasing concentration of total amines. There was a statistically significant relation between total amine concentration and increased risk of reduced bilateral visual acuity and 2.5% contrast sensitivity.
