title: Bacillus cereus panophthalmitis after intravenous heroin.
abstract: Two healthy young black men developed panophthalmitis after intravenous heroin injections. Bacillus cereus, considered to be a relatively noncommon pathogen for man, was found to be the causative agent as it was recovered from the anterior chamber and viterous cavity of both cases. The ocular findings were unilateral in each case, and neither patient had any sistemic involvement from the bacteremia. The onset of visual symptoms varied from 24 to 36 hours after the last intravenous injection with the eye becoming rapidly blind. Photographs of the early fundus lesions included preretinal hypopyon-like lesions and peculiar changes in the blood vasculature. Intracameral gentamicin and steroids did not alter the cause, and treatment was enucleation.
