1963年Sonking及1974年浙江、福建资料曾提出“视网膜点彩”为铅中毒早期诊断指标之一。现对29名确诊的铅中毒患者和33名不接触任何毒物的正常人进行眼底观察,结果如下: 检查对象 1.劳动条件较差的某铅锌矿确诊为慢性铅中毒的炼铅工24名;误将红丹为“雄黄”泡酒服用致急性铅中毒的患者3名;口服“铅丹”致亚急性铅中毒者2名。共男27名,女2名。平均年龄35岁。 2.选年龄相近(平均34.5岁)无毒物接触史的正常人33名作为对照组,以免因年龄不同造成眼底色素沉着的差异。
1963 Sonking and 1974, Zhejiang, Fujian data have put forward “retinal spot color” as one of the early diagnostic indicators of lead poisoning. The findings of the fundus observation of 29 confirmed lead poisoning patients and 33 normal people not exposed to any toxicants are as follows: Check the target 1. Some lead-zinc mine with poor working conditions 24 lead smelters with chronic lead poisoning ; Mistakenly to Hongdan as “realgar” soak lead to acute lead poisoning in patients with 3; oral “lead Dan” subacute lead poisoning in 2. A total of 27 male and 2 female. The average age is 35 years old. 2. Select the age of similar (average 34.5 years old) non-toxic contact history of 33 normal people as a control group, so as to avoid different age differences caused by fundus pigmentation.
