Mechanism of action

By delivering antibiotics directly to the vitreous humor, this approach achieves high local drug concentrations at the site of infection while minimizing systemic exposure and side effects. This route is particularly useful for treating endophthalmitis and other intraocular bacterial infections that are difficult to reach with systemic antibiotics due to the blood-retinal barrier. The direct intravitreal administration allows for rapid antimicrobial action against bacteria colonizing the posterior segment of the eye.
