Health effects visual acuity

The accidental release of several tons of MIC in 1984 at Bhopal, India, resulted in a very heavy death toll (approximately 1850) and, in survivors, significant impairment of health. Immediate symptoms were difficulty in breathing, skin and eye irritation, vomiting, and unconsciousness. Only a few deaths were recorded in the first few hours, with the maximum number of fatalities occurring between 24 and 72 hours. The predominant cause of death was cardiac arrest following severe pulmonary edema. Lung function abnormalities have persisted years after exposure. Ophthalmic effects included lacrimation, lid edema, photophobia, and ulceration of the corneal epithelium. A follow-up study 3 years after exposure showed excess irritation, eyelid infection, cataract, and a decrease in visual acuity, but corneal erosion was resolved. ...
