[One case of cataract caused by occupational trinitrotoluene].

This study analyzed a patient with occupational trinitrotoluene cataract, summarized occupational history, clinical manifestations, and relevant ophthalmic examinations for the diagnosis of occupational diseases, and provided a reference for the diagnosis, prevention and treatment of such occupational diseases. This patient had long-term exposure to trinitrotoluene, experiencing blurred vision and photophobia for more than half a year. After undergoing comprehensive vision improvement and other examinations in the ophthalmology department, trinitrotoluene cataract was considered. After discussion, the patient was diagnosed with stage one occupational trinitrotoluene cataract in accordance with GBZ 45-2010 "Diagnostic Criteria of Occupational Trinitrotoluene Cataract". Occupational exposure to trinitrotoluene can cause lens damage and subsequently lead to cataracts. Attention should be paid during occupational activities and enhanced protection measures should be taken.
