Blepharitis in Dogs
Blepharitis is an inflammation of the eyelids. The most common causes are bacterial infections, demodectic mites, trauma, sun sensitivity, abscesses, and as extensions of or accompanying other eye diseases. Inflammation of the lid margins is called pyogranulomatous blepharitis.
Signs of Blepharitis
The eyelids are red and swollen, and the lid margins are usually encrusted with pus discharge. The eyelids are often itchy, so the dog will paw at the eyes. Excessive blinking and sensitivity to light are also evident. Blepharitis is nearly always accompanied by conjunctivitis.
Diagnosis of Blepharitis
The diagnosis is made by the signs and a physical examination. In some cases biopsy of the lid lesions may be needed.
Treatment of Blepharitis
Treatment is directed at removing the cause. Most cases are either caused by, or accompanied by, bacterial infection, so antibiotic eye ointments are used in treatment. Dogs usually respond well to a course of prednisolone over three weeks or cephalexin. Flushing out the eyes and removing the encrusted discharges are also important in treatment.
