What is the recommended treatment for bacterial keratitis or corneal ulcers?

Topical fluoroquinolone drops are the recommended treatment for bacterial keratitis or corneal ulcers because they provide broad-spectrum coverage against a variety of bacteria that commonly cause these conditions. Fluoroquinolones are particularly effective due to their ability to penetrate the cornea effectively while also being potent against both gram-positive and gram-negative organisms, which are frequent culprits in corneal infections.

The use of topical fluoroquinolones helps to quickly control bacterial growth, reducing the risk of complications such as corneal scarring or perforation. Initiating treatment promptly is crucial in managing corneal ulcers to preserve vision and ensure better outcomes.

Other options, such as oral antivirals and topical corticosteroids, are not appropriate for bacterial infections, as they target viral infections or reduce inflammation rather than directly combat bacterial pathogens. Corneal transplant is a procedure that may be necessary in advanced cases or when vision is severely compromised, but it is not a first-line treatment for active bacterial keratitis or ulcers. Thus, topical fluoroquinolone drops are the primary and most effective choice for treating bacterial keratitis and corneal ulcers.
