Dog and Human Bites
Tearing and crushing injuries occur secondary to dog or human bites. Partial-thickness and full-thickness eyelid lacerations, canthal avulsions, and canalicular lacerations are common. Tissue loss is uncommon but may occur. Irrigation and early wound repair are preferred, and tetanus and rabies protocols should be observed. Systemic antibiotics are recommended for mixed organism flora specific to dog bites, which most often include Pasteurella canis, as well as aerobes (streptococci, staphylococci, Moraxella, and Neisseria), and anaerobes (Fusobacterium, Bacteroides, Porphyromonas). Ocular and canalicular injuries are seen most commonly in children, and more often in association with dog bites from mixed breeds, German shepherds, Labrador retrievers, pit bull terriers, and rottweilers.
