Some rabbits may not have well developed tear ducts. Culturing for bacterial infection is often difficult, so we normally treat topically, for a while, in case there is an infection. Your veterinarian may choose to flush the tear ducts with an antibiotic solution and prescribe an ophthalmic ointment for you to apply at home. If the apparent infection extends to other areas, your vet will undoubtedly start your bunny on systemic as well as topical antibiotics. While house rabbits don't need extraordinary sanitation in their living environment, extra care is needed to keep household bacteria out of cuts or open wounds.
