Keratomycosis in captive red pandas (Ailurus fulgens): 2 cases.

Two cases of keratomycosis in captive red pandas (Ailurus fulgens) were diagnosed and treated at a zoo in Melbourne, Australia across a 9-year period. Both cases presented with severe unilateral ocular pain and stromal abscessation of the cornea. A superficial keratectomy was performed in both cases and the diagnosis was confirmed with either cytology or histopathology. Following surgery, a combination of oral, topical and subconjunctival medical therapy contributed to a successful outcome.

Conjunctival lymphoma: immunophenotype and outcome in five dogs and three cats.

Conjunctival lymphoma is well documented in the medical literature, but veterinary reports are few. We report five cases of canine lymphoma, and three of feline in which the presenting sign was conjunctival involvement. All animals were in apparently good health at the time of presentation, and attended the referring clinic because of conjunctival disease. One dog showed generalized lymphadenopathy at presentation, although the ocular lesion was the reason for consultation, but all other patients were well with no detectable disease beyond the eye. All cats were presented for their ocular disease. All dogs were confirmed to have T-cell tumors, although the histological appearance of these was variable. In contrast, all cats had B-cell tumors. Referring clinicians and owners were contacted for follow-up information. Three dogs had been euthanased within 6 months of diagnosis for deterioration of general health. The remaining two were alive and showed no signs of systemic disease. Two cats had good survival following diagnosis, the other died of lesions that may not be related.

Surgical management and outcome of lower eyelid entropion in 124 cats.

OBJECTIVES: To evaluate the success rate of various surgical techniques for the management of lower eyelid entropion in cats. DESIGN: Retrospective study. Animals studied One hundred and twenty-four cats with surgical correction of lower eyelid entropion of 200 eyes over a 13 year period. METHODS: Records of 124 cats were reviewed for signalment, type of entropion, surgical procedure performed and post-operative result. RESULTS: Combinations of the Hotz-Celsus (HC), lateral canthal closure and full thickness wedge resection techniques were used to treat 64 bilateral and 60 unilateral cases of lower lid entropion. Twenty-three cats were under a year of age, 52 cats were aged between 2 and 8 years and 49 were over 8 years old. The overall success rate for a single surgical procedure (which may consist of multiple techniques) to correct lower eyelid entropion was 96.0% per eye. The remaining 4.0% had the entropion resolved with a second surgery. A combined HC and lateral canthal closure had a 99.21% success rate of resolving lower lid entropion. Geriatric cats were the most likely age group to develop corneal sequestra; 37% of cats in this group presented with entropion and corneal sequestra concurrently. Seventeen percent of cats that presented with unilateral entropion and did not have prophylactic surgery on the fellow eye went on to develop entropion in the fellow eye. CONCLUSIONS: A combined HC and lateral canthal closure was the most effective surgical technique in managing lower eyelid entropion of cats in our study. Prophylactic lateral canthal closure in the unaffected eye is recommended.

Taenia serialis causing exophthalmos in a pet rabbit.

A 16-month-old, male, neuter Dwarf Lop rabbit presented with exophthalmos of the right eye of 3 weeks duration. Under sedation an ultrasound of the right eye was performed and showed an orbital hypo-echoic area posterior and ventrolateral to the right globe, which was presumed to be a cyst. Fine needle aspirate removed 5.5 mLs of straw-colored fluid from the cyst, which allowed the globe to return to its normal position. Two months later the rabbit re-presented with exophthalmos of the right eye. Exploratory surgery was performed and a large cystic structure was removed from the ventro-lateral conjunctival fornix. Histology confirmed the cyst to be a coenurus of Taenia serialis.
