Qualitative and quantitative effects of 0.5% proparacaine on corneal bacterial culture results in dogs, cats, and horses

Purpose of Study: If your veterinarian suspects that your animal is suffering from infectious keratitis (infection of the cornea) or a deep corneal ulcer, they will recommend taking a swab sample from the surface of your cat’s cornea to determine the type of infection. Historically at UC Davis, we have used a topical anesthetic named proparacaine, that is applied to the surface of the eye before any samples are taken to minimize discomfort. Recently, a concern has been raised that proparacaine may inhibit growth of infectious organisms in the laboratory after a corneal swab sample is obtained. This means that even if your cat has a corneal infection, we may not be able to grow the bacteria or fungi in the lab if proparacaine has been used before sample collection. Therefore, the purpose of this study was to determine the best procedure to follow when collecting culture samples, thereby ensuring an appropriate diagnostic work up and treatment plan while minimizing discomfort.
