Early equatorial cataracts in workers exposed to trinitrotoluene.
Twelve workers (nine men and three women with a mean age of 39.5 +/- 8.9 years) with occupational exposure to trinitrotoluene had a mean duration of exposure of 6.8 +/- 4.7 years. The general physical findings were minimal, but ophthalmologic examinations showed bilateral peripheral cataracts in six of the 12 workers. Cataracts were visible only with maximal mydriasis and were continuous or annular opacities at the equator. The cataracts did not interfere with visual acuity or visual fields. Only one worker with and one without cataracts had increased serum alanine aminotransferase and bilirubin levels, possibly associated with trinitrotoluene exposure.
