Dog follicular conjunctivitis: symptoms and treatment

This is a chronic inflammatory disease that affects the lymphatic follicles of the mucous membrane. Follicular conjunctivitis in dogs is often a complication of other forms of conjunctivitis, usually catarrhal, allergic. Named because of the formation of follicles filled with pus. Other symptoms typical of conjunctivitis.

Etiology of follicular conjunctivitis

The causes of the disease are:

  • trauma from sand, branches, grains;
  • burn from ultraviolet rays;
  • dusty air, smoke;
  • unsanitary conditions;
  • ingress of various substances (household chemicals, construction dust);
  • allergy to paints, pollen.

There were no cases when bacterial or viral infection of the eyes led to follicular inflammation. But it can develop as an addition to more dangerous diseases, such as plague, adenovirus or parvovirus infections.

Importantthat follicular inflammation develops as a complication of catarrhal conjunctivitis. That is, it is almost always secondary. This disease is characteristic of young dogs up to a year old, most often due to pedigree pathology of the eyelids.

Symptoms of the disease

Both eyes are usually affected, but with varying degrees of intensity. Initially, the disease proceeds according to the catarrhal type of inflammation, which is characterized by the following symptoms:

  • photophobia;
  • conjunctival redness;
  • swelling of the eyelids;
  • blepharospasm;
  • mucous discharge from the eye;
  • sore conjunctiva and eyelids.

Then the disease passes into follicular conjunctivitis. Exudate may remain mucous, or may become mucopurulent, transparent gray, its amount may be large or small, it all depends on the severity of the inflammation. When follicles are connected to the process, the third eyelid becomes like a raspberry, it is red, completely covered with “warts”. The eyelids swell, in severe cases, they may be inverted, which leads to inflammation of the cornea. If the disease is not treated, then there are ulcers on the cornea.

Follicular conjunctivitis treatment

When the first signs appear, it is necessary to begin to clean the sore eye with a cotton ball, moistening it in chamomile broth. It is forbidden to use one ball twice, even in the absence of visible traces of contamination. It will be useful to limit walking with the pet so that it does not catch the infection, and that the disease is not complicated by purulent inflammation.

With the further development of the disease and the intensification of symptoms, you should definitely contact your veterinarian for the correct appointment of treatment. Of the drugs, drops or ointments containing antibiotics are mainly prescribed. It can be drops of 10%, 20% and 30% sulfacyl sodium solution or 25% Sofradex solution 4-5 times a day.

Of ointments, the following are used:

  • chlortetracycline ointment;
  • 30% sulfacyl sodium;
  • tetracycline ointment;
  • ointment with a content of 30-50% etazole.

A novelty in the world of veterinary medicine was the ophthalmic drug films developed by E.P. Kopenkin. Their structure includes kanamycin, neomycin, sulfapyridazine sodium. Apply them by introducing into the conjunctival sac once a day. Upon contact with a tear, the film swells, attaching to the conjunctiva. Then it dissolves, giving the mucous membrane nutrients.

The veterinarian can perform follicle removal surgery:

  • First, anesthesia is done using 10% novocaine.
  • The eyelids are pushed back with tweezers with soft teeth.
  • Swollen follicles are "extinguished" with a silver nitrate stick (one should not touch the cornea).
  • Then they immediately rinse the conjunctiva with an isotonic solution to wash off the residues of silver nitrate.

Usually enough 4-5 procedures. In the presence of large follicles, their surgical removal can be used, but it is not desirable, since it leads to a curvature of the eyelid.

The operation is carried out as follows:

  • First they do anesthesia using 10% novocaine.
  • The eyelids are pushed back with tweezers with soft teeth.
  • Inflamed follicles are scraped off with a curette.
  • Then apply an eye film.

In the presence of significant edema, a solution of 0.1-0.2 ml of hydrocortisone or 0.5-1 ml of dexazone is used under the conjunctiva. During treatment, the eyes of the pet should be washed 3-4 times a day with a decoction of chamomile. To prevent the dog from scratching its eyes, you need to wear a collar on it.
