Follow-up Examinations for Ocular Neoplasms and Pigmented Ocular Lesions at the DuPont Belle, West Virginia Plant.
NIOSH 1980 Mar:48 pages
The incidence of ocular lesions among workers at DuPont Belle in West Virginia was investigated in 1979. The study population included 365 workers, some of whom had been examined the previous year and were diagnosed with ocular disorders. Subjects were given ophthalmological examinations, and records from the examination the year before were reviewed. One worker had choroidal melanoma that had changed in size and color since the 1978 examination. A worsening of choroidal nevi occurred in 1 of 50 workers diagnosed in 1978. Three new cases of choroidal nevi were found in 1979. Among 146 workers with iris nevi in 1978, additional lesions were found in 8 workers; two new cases were identified. Changes were seen in a conjunctival nevus in one worker. Most of the workers with elevated or borderline intraocular pressures in 1978 still had abnormal pressures in 1979. The authors recommend care ophthalmological monitoring of workers with evidence of ocular disease.
