Early equatorial cataracts in workers exposed to trinitrotoluene
American Journal of Ophthalmology
|June 1, 1983
Summary
Occupational exposure to trinitrotoluene (TNT) may cause peripheral cataracts in workers. These vision changes, though present, did not impact visual acuity or fields in the studied group.
Area of Science:
- Occupational health
- Ophthalmology
- Toxicology
Background:
- Trinitrotoluene (TNT) is an industrial chemical with known toxic effects.
- Ocular health risks associated with TNT exposure are not well-documented.
Purpose of the Study:
- To investigate the ophthalmologic findings in workers with occupational exposure to TNT.
- To assess potential correlations between TNT exposure and ocular abnormalities.
Main Methods:
- Ophthalmologic examinations were conducted on 12 workers with occupational TNT exposure.
- Medical histories and general physical findings were recorded.
- Serum levels of alanine aminotransferase and bilirubin were analyzed.
Main Results:
- Six of the 12 workers developed bilateral peripheral cataracts.
- Cataracts were equatorial, visible only under maximal mydriasis, and did not affect visual acuity or fields.
- Abnormal liver enzyme levels were observed in one worker with cataracts and one without.
Conclusions:
- Occupational exposure to TNT may be associated with the development of peripheral cataracts.
- The observed cataracts did not impair visual function.
- Further research is needed to confirm the link between TNT and cataract formation and to evaluate other potential health effects.
