[Bacterial corneal ulcer treated with intrastromal antibiotic. Experimental model in vivo].

Objective: To compare the therapeutic effectiveness of a single intrastromal dose of gentamycin, tobramycin, ciprofloxacin and ofloxacin for the treatment of corneal ulcers due to Pseudomonas aeruginosa.

Methods: Twelve white female New Zealand rabbits underwent mechanical removal of corneal epithelium; then one drop of salt suspension containing Pseudomonas aeruginosa (75,000,000 colony forming units) was instilled over the Bowman's layer. Rabbits were distributed in five groups according to the type of antibiotic used: group A: gentamycin, group B: tobramycin, group C: ciprofloxacin, group D: ofloxacin and control groups.
