The conjunctiva is the moist tissue that covers the front part of the eyeball and lines the eyelids. Breeds that tend to have allergies or autoimmune skin diseases tend to have more problems with inflammation of the conjunctiva. They are also more likely to have dry eyes, the result of a disease in which the animal is allergic to substances in the environment, such as pollen, that would not normally cause health problems. Otherwise, there does not appear to be a breed predilection for this disease.
Conjunctivitis can affects both dogs and cats. If you would like to learn more about how this disease affects cats, please visit this page in the PetMD health library.

The first thing your veterinarian will look for is evidence of other ocular (eye) diseases. For example, the disease may not be in the conjunctiva but in other parts of the eye. Your doctor will conduct a complete eye exam. Different methods of examination may include a fluorescein stain, which is spread on the surface of the eye to make scratches, ulcers, and foreign material stand out under light. This is to rule out ulcerative keratitis. Foreign materials may also have gotten caught in the lids or eyelashes, so they will be examined thoroughly as well. A test for glaucoma will be conducted by determining pressures in the eye, and the nasal cavity may need to be flushed out to rule out disease there. If there is discharge from the eye a culture will be done to determine what the discharge consists of, since infection may be indicated, and a biopsy of conjunctiva cells may be collected for microscopal examination. A skin test may also be conducted if skin allergies are suspected to be the cause.
