The purpose of this study was to determine clinical features of canine episcleritis and outcomes of therapy in Korea. The medical records of dogs with episcleritis presented at the Veterinary Medical Teaching Hospital of Seoul National University from January 2006 to December 2007 were reviewed. Episcleritis was diagnosed in 17 eyes of 12 dogs. The most frequently affected breed was Shih Tzu (n = 6). The median affected age was 5 years with a range from 3 years to 12 years. Simple episcleritis was identified in 8 dogs, nodular granulomatous episcleritis (NGE) in 3 dogs, and secondary episcleritis caused by panophthalmitis in a dog. The combination immunosuppressive therapy of topical corticosteroids, topical cyclosporine A, and intralesional injection of triamcinolone (4 mg) and gentamicin (4 mg) was performed. Most of the patients with episcleritis were resolved within 30 days following the therapy. Surgical excision was performed in 1 NGE case which was not responded to the medical therapy. Recurrence was observed in 4 dogs between 5 and 8 months after the first visit. It is considered that strong immunosuppressive therapy and periodic ocular examination are needed to control episcleritis.

A 6-year-old spayed female American Cocker Spaniel presented with episcleritis in the right and then the left eye (OS) at eight month interval. Repeated intralesional triamcinolone acetonide was administered subconjunctivally to both eyes (OU). During this period, scleral ectasia was revealed on ocular funduscopy OS and then confirmed on ultrasonography and computed tomography. A year later, conjunctival hyperemia occurred around remnant triamcinolone particles and was treated by resection of these particles in the OU. A recurrence of episcleritis, which did not regress, required repeated triamcinolone subconjunctival injections four months later in the OU. Four months after these injections OU, the dog was presented with bilateral conjunctival mass, which had developed over the previous month. The round-shaped masses with diameters of 1 cm were surgically resected from exposed scleral ectasia lesion of thin and bulging scleral surface in the OU. The cross-section of both masses showed a white-colored accumulation at the center and triamcinolone induced granulomas enclosing necrotic tissue were confirmed by impression cytology and histopathological examination.

A 5-year-old castrated male Cocker Spaniel was referred to Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic conjunctival hyperemia and a fleshy corneal mass in the right eye. On ophthalmic examinations, it was observed that a well-vascularized fleshy mass at the dorsolateral limbus extended into the clear cornea. The lesion regressed by initial medications, including both topical and systemic corticosteroids, and topical cyclosporine A. However, the lesion relapsed and grossly infiltrated to cornea in a short period of time without improvement in spite of the immunosuppressive therapy, leading to the vision loss. The eye was enucleated and nodular granulomatous episclerokeratitis was confirmed on histopathological examination.
