  • An 1.6-year-old female Shih Tzu was presented with corneal perforation, descemetocele, and deep corneal ulcer in the left eye. A bovine amniotic membrane graft which preserved in lyophylized dry form and a third eyelid flap were applied. After 14 days, the cornea was fluorescein-negative. At day 42 postoperatively, only a moderate scar at the corneal center was showed. At the 10-month follow-up, there was clear cornea with a mild scar.

  • 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.

  • A 4-year-old castrated male Shih-Tzu was presented to the Chonbuk National University Animal Medical Center with a history of melting ulcer in the right eye (OD). Upon ophthalmologic examination, severe keratomalacia of approximately 70% of the entire surface area with a full thickness corneal defect was found in OD. In addition, iris and fibrin clots were observed on the center of the corneal defect. The menace response and dazzle reflex were normal in OS. As the size and damage of corneal perforation was so severe, amniotic membrane (AM) transplantation was considered to repair the cornea instead of direct suture technique, flap methods or corneal transplantation. Equine AM was sutured to the limbus to cover the entire cornea in a single interrupted pattern using 9-0 nylon suture material. On day 79, mild scarring and pigmentation, with almost no vasculature, remained. The menace response and dazzle reflex were normal of OD. Although pigmentation and scarring remained on the cornea, equine AM transplantation can be useful for reconstruction of severe corneal perforation with keratomalacia.
