Evaluation of vitreous degeneration as a potential risk factor for retinal detachment after phacoemulsification in dogs.

Purpose: To evaluate vitreous degeneration as a potential risk factor for retinal detachment in dogs after phacoemulsification.

Methods: Medical records for dogs with preoperative ocular ultrasound and phacoemulsification between September 28, 2006, and August 2, 2016, were reviewed. Ultrasound images were reviewed by two observers independently, and vitreous echogenicity was graded using an established scale.

Ophthalmic findings in a captive population of Panamanian golden frogs: Atelopus zeteki.

Purpose: The aim of this study was to describe normal ocular morphology and establish parameters for select diagnostics in a population of Panamanian Golden Frogs (PGF) Atelopus zeteki maintained at the Detroit Zoo.

Method: A total of 22 toads free of ocular disease were included in this study. Ophthalmic diagnostic tests included as follows: endodontic absorbent paper point tear test (EAPPTT), assessment of intraocular pressures (IOP), Rose Bengal stain, palpebral fissure width, blink rate and corneal cultures.

INTRAOCULAR PRESSURE IN SOUTHERN ROCKHOPPER (EUDYPTES CHRYSOCOME) AND MACARONI PENGUINS (EUDYPTES CHRYSOLOPHUS): EVALUATION OF INFLUENCING FACTORS.

Ophthalmic examinations were performed on 160 macaroni penguins (Eudyptes chrysolophus) and 90 southern rockhopper penguins (Eudyptes chrysocome) at eight North American zoos and aquaria. Intraocular pressure (IOP) was measured using rebound tonometry while penguins were held in two different body positions. Correlations between IOP and factors including age, body position, eye pathology, and housing parameters were evaluated.

Ocular findings and reference values for selected ophthalmic diagnostic tests in the macaroni penguin (Eudyptes chrysolophus) and southern rockhopper penguin (Eudyptes chrysocome).

Objective: To describe ophthalmic examination findings and standard diagnostic test results in 2 penguin species.

Animals Studied: Macaroni & Southern Rockhopper Penguins.

Procedure: Complete ophthalmic examinations including Schirmer tear test (STT), modified phenol red thread test (PTT), tonometry, and echobiometry were performed on penguins housed at the Detroit Zoo.

Periocular cutaneous mast cell tumors in cats: evaluation of surgical excision (33 cases).

Objective: To describe feline periocular cutaneous mast cell tumor (CMCT) clinical features, rates of local tumor recurrence and metastases, and cat survival time following surgical excision.

Animals Studied: Thirty-three cats with periocular CMCTs.

Procedures: Medical records of cats diagnosed with periocular CMCTs were reviewed; cats were included if CMCTs were surgically excised and the diagnosis confirmed by histopathology.

Surgery of the eyelids.

Eyelid fit and function are important for maintaining ocular surface health. Some common conditions, which affect these parameters, include abnormal cilia, inappropriate eyelid conformation, eyelid trauma, and neoplasia. When these conditions are associated with discomfort and compromised corneal health, surgical intervention is indicated.

Lacrimal cystadenoma in a Chinese box turtle (Cuora flavomarginata).

An adult male Chinese box turtle (Cuora flavomarginata) presented to the Avian and Exotic Pet Service of the Animal Medical Center for periorbital swelling of the right eye. The swelling had failed to respond to nutritional supplementation and parenteral administration of vitamin A. What had initially presented as periorbital swelling developed into a growth ventral to the globe that impeded vision and was frequently traumatized by forelimb movements of the turtle.

Management of eyelid neoplasms in the dog and cat.

Eyelid neoplasms are common in the older dog and typically benign. Eyelid neoplasms in the cat are less common and more often malignant. Resection of eyelid masses may be curative; however, restoration of the eyelid structure after mass excision is essential for maintaining long-term ocular surface health.

Use of posaconazole in the management of invasive orbital aspergillosis in a cat.

Orbital infection with Aspergillus fumigatus was diagnosed in a Persian cat that was presented with chronic third eyelid protrusion and exophthalmos. Evidence of nasal, sinus, or disseminated aspergillosis was not detected in this cat. Complete surgical excision of diseased tissues was not possible during orbital exenteration, and infection subsequently extended into the tissues of the oral cavity.
