为了进一步阐明二硫化碳(CS_2)视网膜病变的发病机理,作者重新分析了143名接触CS_2工人及40名对照组工人1967～1972五年间接受眼底视网膜荧光血管造影患者的彩色眼底照片。结果表明:(1)视网膜血管囊状微动脉瘤(microanurysm):接触组占45.5%,对照组占7.5%(P<0.05);(2)小血管扭曲并有椭圆形微动脉瘤和小血管襻形成:接触组 To further elucidate the pathogenesis of CS2 retinopathy, the authors reanalyzed the color fundus images of 143 CS2 workers and 40 control workers who underwent retinal fluorescein angiography between the years 1967 and 1972. The results showed that: (1) microanurysm in retinal vessels was 45.5% in the contact group and 7.5% in the control group (P <0.05); (2) Small vessel distorted with oval microaneurysm and small vessel襻 form: contact group
