This study was performed to investigate the signalment, cause and clinical feature of corneal diseases of dogs in Korea. One hundred eighty-four dogs(273 eyes) with corneal diseases were examined and classified into congenital, inflammatory and metabolic diseases. Inflammatory diseases were subclassified into nonulcerative keratitis and ulcerative keratitis. The most prevalent corneal disease type was inflammatory disease(93.7%) and nonulcerative keratitis(58.6%) is more prevalent than ulcerative keratitis(35.1%) in the inflammatory diseases. The main cause of nonulcerative keratitis was keratoconjunctivitis sicca(19.0%) whereas that of ulcerative keratitis was trauma(9.9%). The most common breed with corneal disease was Shih Tzu(49.5%). The affected mean age was $6.4{\pm}4.1$ years old. The prevalence rate of corneal diseases were slightly higher in female(56.8%) than in male(43.2%). The data of corneal diseases in dogs obtained from this study will be utilized in prevention, diagnosis and treatment of corneal diseases in dogs and client education.

A 6-year-old spayed female Persian cat presented with a 3-month history of recurrent ulcerative keratitis with noticeable opacification and vascularization of the right cornea. The lesion was nonresponsive to topical antibiotics and to nonsteroidal anti-inflammatory drugs. Ophthalmic examination showed signs of ocular discomfort, such as epiphora and blepharospasm, in the right eye. Biomicroscopic examination revealed an irregular, edematous, vascularized mass with pink to white tissue on the entire cornea and mild conjunctivitis. A tentative diagnosis of feline proliferative eosinophilic keratitis (FPEK) was made on the basis of clinical appearance. Cytologic examination of the cornea showed a mixture of numerous eosinophils and mast cells, which confirmed the original diagnosis of FPEK. The cat was treated with a topical antibiotic-corticosteroid combination, cyclosporine ointment, trifluridine eye drops, and oral Llysine. The clinical signs improved remarkably 18 days after the cat was first examined. The short-term use of corticosteroids and long-term use of cyclosporine and an anti-viral agent resolved the lesion without recurrence of the disease for 1 year.

A 13-year-old, female, Shih-tzu and a 10-year-old, female, Yorkshire terrier were presented with ulcerative keratitis caused by corneal endothelial degeneration. Generalized corneal edema, conjunctival hyperemia, focal corneal pigmentation, corneal neovascularization, sub-epithelial bullae, and positive fluorescein staining were observed during ophthalmic examinations. Thermokeratoplasty was performed on the overall edematous corneas. Healing of the cornea was completed within 25 days and corneal ulceration has not recurred after healing of the cornea in both cases. Other ocular complications were not observed except for a slight increase in corneal pigmentation. According to this study, thermokeratoplasty could be an effective treatment for corneal ulceration secondary to corneal endothelial diseases in dogs.

A 6-month-old male thoroughbred foal with melting ulcer after left eye trauma was referred to Equine Hospital of Jeju National University. The left eye did not respond to the menace reflex test. Bacteria were not observed on corneal smear and culture test, and fluorescein staining revealed corneal injury. Subpalpebral Lavage (SPL) catheter was installed through the upper left eyelid. And the antibiotics, mydriatic and antifungal agents were administered using SPL. In addition, temporary tarsorrhaphy was performed and a hard cup hood was applied. After 2 weeks, the temporary tarsorrhaphy was removed and severe corneal neovascularization was found. On the 39th day of treatment, the left eye was responding to the menace reflex test and granular tissue formation was confirmed in the ulcer area. During the 2 months follow-up, we found that the granulation tissues decreased significantly. This case report describes a successful recovery of severe melting ulcers in a foal by intensive treatment.
