Initial therapy of suspected microbial corneal ulcers. I. Broad antibiotic therapy based on prevalence of organisms.

The initial treatment of bacterial ulcers of the cornea should consist of a combination of antibiotics that are effective against the major pathogens in the community. A gram stain may be misleading and therefore may suggest inappropriate therapy. Antibiotic therapy should include subconjunctival injections and concentrated eye drops, but not systemic administration except following perforation. Initially, we use cefazolin and tobramycin or gentamicin. Bacitracin may be substituted as a topical medication. Antibiotic therapy should be changed only if the pathogen is reported to be resistant to initial therapy and if the corneal ulcer continues to worsen.

Keratoconjunctivitis sicca.

KCS in man is often associated with a systemic disease whose pathogenesis is still obscure. A spontaneous animal model resembling Sjögren's syndrome has been developed in the NZB and NZB-NZW mouse. Other spontaneous animal models analagous to lupus erythematosis and polyarteritis have been found in dogs and Aleutian mink, respectively. Studies of the eyes and lacrimal glands in such animals, and in dogs with distemper, should be pursued. A viral etiology is implicated in each of the models. The roles of both the main and accessory lacrimal glands in normal and KCS eyes have been discussed, as well as drug-induced KCS and opportunities for its further investigation and treatment.
