Acute bilateral visual impairment in a drug addict. A case report.
A 27-year-old male with a sudden visual loss in both eyes following an intravenous injection of 3 crushed tablets of Ketobemidon (Ketogran) is presented. However, a mixture of illegal drugs was suspected because of a history of previous heavy drug addiction. Quinine, a well-known additive in illegal narcotics could thus be suspected as the causative agent because of earlier episodes of reduction in visual acuity. An alternative diagnosis is embolism of both retinal central arteries.
