Experiments conducted in rabbits showed no toxic effects on the retina by electroretinogram after vitrectomy when the infusion fluid contained as much as 50 microgram/ml of methicillin or lincomycin or 20 microgram/ml oxacillin. An abnormal electroretinogram was found in eyes receiving oxacillin in a concentration of 50 microgram/ml. Histologic studies showed ocular damage with concentrations of 50 microgram/ml of methicillin or lincomycin or 20 microgram/ml of oxacillin. All antibiotics were nontoxic to retina at 10 microgram/ml concentration, both by ERG and histology.
