Summary
Using color fundus photography, the occurrence of retinopathy was studied in Japanese and Finnish viscose rayon workers and unexposed control subjects. Interobserver error was avoided by strict method control. Retinopathy (microaneurysms/small dot hemorrhages) was detected in 103 of 419 Japanese exposed (24.6%) and in 7 of 188 Finnish exposed subjects (3.79% (P < 0.05). The respective prevalences for the unexposed subjects were 3.8% and 2.6%. The retinopathy due to carbon disulfide, “retinopathia sulfocarbonica”, seen in Japanese viscose rayon workers did not occur in Finnish workers.
