537名接触CS_2工人的周边视野检查结果:视野缩小在10°以内占79.1%,在10°～20°占14.8%、20°～30°占5.2%,大于30°占0.9%。按照流行病学的发病规律和疾病的分级标准,作者建议,在职业史和临床表现基础上,以测定周边视野诊断CS_2慢性中毒。视野缩小10°以内为正常,10°～20°为慢性CS_2中毒的观察对象,20°～30°为慢性CS_2轻度中毒,30°以上为慢性CS_2重度中毒。我们也注意到颞侧视野缩小的发生率明显比鼻侧为高,而左眼较右眼为明显。对此现象尚需进一步研究。
Results of peripheral visual field examinations of 537 workers exposed to CS_2 showed that the field of view reduced to 79.1% within 10 °, 14.8% from 10 ° to 20 °, 5.2% from 20 ° to 30 °, and 0.9% from 30 °. In accordance with epidemiological rules and disease grading standards, the authors suggest that in the basis of occupational history and clinical manifestations, to determine the peripheral vision of the diagnosis of CS2 chronic poisoning. Visual field reduced to within 10 ° as normal, 10 ° ~ 20 ° for chronic CS_2 poisoning observed objects, 20 ° ~ 30 ° for chronic CS_2 mild poisoning, 30 ° for chronic CS_2 severe poisoning. We also noticed that the incidence of temporal visual field reduction was significantly higher than that of the nasal side, whereas the left eye was more pronounced than the right eye. This phenomenon needs further study.
