When the conjunctiva tissue (the mucous membrane around the eyeball and eyelids) is inflamed, that’s conjunctivitis. Dog breeds that are predisposed to allergic or immune-mediated skin diseases often get conjunctivitis — and some purebred cats are susceptible to infectious conjunctivitis. Along with the swelling and discharge, you might see blepharospasms (involuntary blinking or closing the eyes). Cats might also develop an upper respiratory infection. Your veterinarian will determine the type of infection — bacterial or viral — and begin the appropriate treatment. (In dogs, conjunctivitis can involve the canine distemper virus, while cats might be infected with a feline herpesvirus or a calicivirus. Your vet will look for underlying cause(s) and might prescribe antibiotics. Unless other diseases are involved (like uveitis or ulcerative keratitis) you and your pet will be sent home with medications (drops or ointment) to apply. If your pet tends to paw and scratch at his eyes, an Elizabethan collar can protect his face.
