Disseminated mite infection with ocular involvement in a juvenile bald eagle (Haliaeetus leucocephalus).

A bald eagle (Haliaeetus leucocephalus) was found unable to fly and was admitted to The Raptor Center (TRC). Major clinical signs were thin body condition and a cardiac arrhythmia. Ten days after admission to TRC, ophthalmic examination revealed multiple, distinct serpiginous lesions of chorioretinal atrophy in the ocular fundus of the right eye (OD).

Photodynamic therapy for the treatment of periocular squamous cell carcinoma in horses: a pilot study.

Objective: Local photodynamic therapy (PDT) is a novel cancer therapy in veterinary ophthalmology. A prospective pilot study seeking to demonstrate proof of principle and safety for the treatment of equine periocular squamous cell carcinoma (PSCC) was therefore conducted. We hypothesized that surgical excision with adjunctive local PDT is an effective and safe treatment for equine PSCC.

Ophthalmic surgical instruments.

With proper training and diligent practice, many orbital, extraocular, and corneo-conjunctival surgeries can be successfully performed by the general practitioner. Specialized surgical instrumentation is necessary to achieve optimal results. This article reviews the essential surgical instruments required for these routine ophthalmic surgeries and provides guidelines for suture selection.

Ophthalmologic and oculopathologic findings in red-tailed hawks and Cooper's hawks with naturally acquired West Nile virus infection.

Objective: To assess ophthalmologic features and ocular lesions in red-tailed hawks and Cooper's hawks naturally infected with West Nile virus (WNV).

Design: Original study.

Animals: 13 hawks.

Keratoconjunctivitis sicca associated with administration of etodolac in dogs: 211 cases (1992-2002).

Objective: To characterize features and response to treatment of keratoconjunctivitis sicca (KCS) associated with oral administration of etodolac in dogs.

Design: Retrospective case series.

Sample Population: 65 cases obtained from a survey of veterinary ophthalmologists (group A) and 146 cases reported to Fort Dodge Animal Health (group B).

Surgical resection of an orbital fat prolapse in a California sea lion (Zalophus californianus).

A 23-year-old captive female California sea lion (Zalophus californianus) developed an inferiotemporal subconjunctival swelling of the right eye. Surgical excision of the mass was performed and a diagnosis of orbital fat prolapse was confirmed histopathologically. There was no recurrence of orbital fat prolapse at 15 months post operatively.

Nonhypotensive autonomic agents in veterinary ophthalmology.

The parasympathetic and sympathetic divisions of the autonomic nervous system are involved in homeostatic control of a wide variety of ocular functions, including accommodation, pupillomotor control, lacrimation, eyelid position, and aqueous humor production. Familiarity with the functional anatomy of the autonomic nervous system is paramount to the understanding and application of the large number of autonomic drugs used in veterinary ophthalmology. The cholinergic and adrenergic agents discussed in this article are commonly employed to facilitate routine ophthalmic examination, in the diagnosis of autonomic dysfunction, and in the treatment of a variety of ocular diseases.

Morphologic features of degeneration and cell death in the neurosensory retina in dogs with primary angle-closure glaucoma.

Objective: To investigate cellular death in the neurosensory portion of the retina during the first 7 days after onset of clinical signs of overt primary angleclosure glaucoma (PACG) in dogs.

Sample Population: 14 globes from dogs with PACG and 2 normotensive globes from dogs with PACG in the opposite eye.

Procedures: Retinas were examined via light microscopy and terminal deoxynucleotidyl transferase-mediated biotin-dUTP nick end-labeling.
