title: Science and strategy for preventing and managing corneal ulceration.
abstract: ABSTRACT Corneal ulcers can cause significant loss of vision from scarring and astigmatism, but rapid management can limit the destruction and improve outcomes. Infectious ulcers usually resolve with antimicrobial treatment. Noninfectious ulcers, however, present a diagnostic and therapeutic challenge. They can often be resolved by eliminating toxic medications and providing surface support with lubrication and collagenase inhibitors, but resistant ulcers may need more aggressive therapy with bandage contact lenses, tarsorrhaphy, or autologous serum. Ulcers impending perforation require urgent surgical management (e.g., tissue glue, conjunctival flaps, or keratoplasty). Topical steroids are useful when the ulceration is secondary to inflammatory mediators, but they are contraindicated in corneal melts with minimal inflammation, such as those associated with Sjogren syndrome. Systemic immunomodulation is required in addition to topical therapy in the presence of autoimmune disease. Understanding of the pathological processes that occur in different types of corneal ulcers is essential to formulation of a logical and effective treatment plan. Newer, more targeted treatment modalities may offer treatment options that have greater efficacy and fewer adverse effects.
