title: Procaine penicillin by subconjunctival injection in the treatment of infectious bovine keratoconjunctivitis.
abstract: A profile off the penicillin concentration in bovine conjunctival sac fluid (CF) was determined after a single subconjunctival injection of procaine penicillin (6 x 10(5) iu in 2ml). When the injection was made through the skin of the upper eye lid, the duration of therapeutic concentration was significantly greater (P<0.01) than when the injection had been given by the perconjunctival route: approximately 68 hours or 40 hours respectively. These findings support the clinical use of subconjunctivally administered procaine penicillin in the treatment of infectious bovine keratoconjunctivitis. A single application of an equivalent dose of either procaine penicillin or benethamine penicillin, applied topically in a simple occulentum base, produced a therapeutic duration in CF of 37 +/- 4 hr and 56 +/- 4.5 hr respectively.
