On two female patients it was shown that intoxication by sedatives containing part bromecarbamide may result in various ocular diseases. The two patients complained of a sudden inexplicable deterioration of vision; semi-dilated slow-responding pupils were diagnosed. Only in one case could a sudden vertical nystagmus be observed. Many possible symptoms were shown. In most cases a discontinuation of drug together with therapy lead to a complete withdrawal of symptoms.
