Update on antibiotics in ocular infections.
Each year, new antimicrobials are found or synthesized in an effort to improve the chance of overcoming infections. In the early 1950s, the only antibiotic available for ocular use was penicillin. Today, ophthalmologists can make a choice from a large selection of antibiotics for ocular infections. The majority of antibiotics have been literally unearthed, since worldwide soil surveys may have been the means of their discovery. In addition, synthetic derivatives of penicillin, cephalosporins, aminoglycosides, and tetracyclines, as well as drugs against tuberculosis and fungi, have become available, and new names have been added to the already bewildering list of less frequently used sulfonamides. However, it takes several years to appreciate the impact of new agents and the continued contribution of older ones. Constant reevaluation is mandatory. The real benefits as well as the untoward effects of a new antimicrobial agent may not be known until several years after the clinical introduction. In addition to approaching infection from the viewpoint of the offending organism and a specific antibiotic to address this organism, one may also approach this problem from the host's immunity. Until now, we have relied largely on the corticosteroids, but one must also consider various nonsteroidal anti-inflammatory agents and, even more importantly, the development of drugs to enhance the host's natural immunity.
