Gentamicin topical therapy

If a significant inflammatory component or a response to bacterial exotoxin hypersensitivity in the fiarm of marginal corneal infiltrates or phlyctenules is present, treatment may require concurrent topical steroid therapy. When chronic dacryocystitis is involved, treatment should include irrigation of the lacrimal system with trimethoprim-polymyxin B or gentamicin. Adjunctive systemic antibiotic therapy may also be required (see Chapter 24).
