Chronal focus of acquired chromatic discrimination loss and solvent exposure among printshop workers

Increased acquired dyschromatopsia among solvent-exposed workers: an epidemiology study on 249 employees of an aluminum-foil printing factory

“…Mergler and Blain [18] found that 52.2% of the 23 workers in a paint factory had dyschromatopsia, with a signi®cant dierence being noted for the 10 most highly exposed workers. In another study, Mergler et al [20] noted that 66% of 30 print workers had dyschromatopsia as compared with 34.9% of the control group. Legault-Belanger et al [17] found that 38.4% of 26 workers in an ink factory had dyschromatopsia as compared with 15.4% in the control group.…”

Blue-yellow deficiency in workers exposed to low concentrations of organic solvents

“…Acquired dyschromatopsia has been associated with exposure to mixtures of solvents, n-hexane, styrene, perchloroethylene, and carbon disul®de (Alieva et al 1985;Braun et al 1989;Campagna et al 1995;Cavalleri et al 1994;Chia et al 1994;Eguchi et al 1995;Fallas et al 1992;Mergler et al , 1988Mergler et al , 1990Raitta et al 1978Raitta et al , 1981. In contrast to the congenital form, acquired dyschromatopsia is not a clinical diagnosis but a symptom mostly caused by diseases of the retina and/or the optic nerve.…”

Impairment of color vision in aircraft maintenance workers

“…Numerous studies have identiWed various demographic and personal characteristics such as age (Lanthony 1986;Bowman 1980;Paramei et al 2004), alcohol consumption (Mergler et al 1988;Paramei et al 2004) and smoking (Paramei et al 2004), and conditions such as diabetes (Duke et al 2007), depression (Melamud et al 2004), and poor visual acuity (Paramei et al 2004) that can aVect the results of testing of color vision (Gobba 2000;Melamud et al 2004;Bowman 1980). We found a strong association between CDV and age.…”
