Gentamicin and other antibiotic toxicitiy.
Antibiotics have the potential to cause significant ocular toxicity when they gain access to the inside of the eye. The aminoglycosides, in particular gentamicin, are the most toxic of the antibiotics commonly used in ophthalmology. Extreme caution should be used when administering a periocular injection of aminoglycoside for treatment or prophylaxis of infection. Intraocular injection of aminoglycoside for gram-negative coverage in endophthalmitis management has been replaced in most cases by ceftazidime. Ceftazidime provides excellent coverage against gram-negative bacteria with less potential for retinal toxicity at therapeutic dosages. Experimental and clinical studies have shown that intraocular vancomycin is safe and effective treatment against gram-positive organisms causing endophthalmitis. A combination of ceftazidime and vancomycin provides broad-spectrum coverage for virtually all bacteria causing endophthalmitis and is the current intraocular treatment of choice.
