Non-invasive blood pressure measurement in conscious rabbits: A comparison of Doppler ultrasonic and oscillometric devices.

Background: This study aimed to compare Doppler (the most commonly used technique for non-invasive indirect blood pressure [NIBP] measurement in rabbits) and oscillometric devices for NIBP measurements in conscious rabbits.

Methods: Blood pressure (BP) measurements were obtained for 49 conscious rabbits using the Doppler and oscillometric devices. Each measurement was repeated in triplicate.

Characterisation of cataracts and other ophthalmic findings in various species of captive penguins.

Background: The identification of ophthalmic diseases that affect vision and/or cause discomfort should be a priority in captive penguins to improve their overall health and quality of life.

Methods: A routine ophthalmological examination was performed on 80 clinically normal penguins (160 eyes), and any lesions observed were recorded.

Results: Ocular lesions were frequent (56% of penguins), with cataracts being the most common (48.

Ocular Ultrasonography and Biometry in the Cinereous Vulture ().

To establish reference standards for ocular ultrasound and biometry, 24 cinereous vultures () (45 eyes) underwent B-mode and A-mode ultrasonographic examination using a 12.5-MHz probe. The vultures were manually restrained without sedation, and the eyes were topically anesthetized.

Characterisation of corneal impression cytology in dogs and its application in the diagnosis of keratoconjunctivitis sicca.

Objective: Determine morphological and morphometric parameters of corneal epithelium in dogs, and determine the cellular alterations that occur in canine keratoconjunctivitis sicca (KCS) using impression cytology.

Study Animals: 60 dogs divided into two groups: dogs with Schirmer tear test (STT) at least 15 mm/minute and absence of ocular disease, and dogs with STT less than 15 mm/minute and clinical signs of KCS.

Procedures: Impression cytology was used to collect corneal samples.

Diagnostic accuracy of electrocardiographic P wave related parameters in the assessment of left atrial size in dogs with degenerative mitral valve disease.

The purpose of this research was to compare the accuracy of newly described P wave-related parameters (P wave area, Macruz index and mean electrical axis) with classical P wave-related parameters (voltage and duration of P wave) for the assessment of left atrial (LA) size in dogs with degenerative mitral valve disease. One hundred forty-six dogs (37 healthy control dogs and 109 dogs with degenerative mitral valve disease) were prospectively studied. Two-dimensional echocardiography examinations and a 6-lead ECG were performed prospectively in all dogs.

ATYPICAL PRESENTATION OF CRYPTOCOCCUS NEOFORMANS IN A KOALA (PHASCOLARCTOS CINEREUS): A MAGNETIC RESONANCE IMAGING AND COMPUTED TOMOGRAPHY STUDY.

Cryptococcosis is a worldwide and potentially fatal mycosis documented in wild and captive koalas ( Phascolarctos cinereus ) caused by Cryptococcus neoformans . Though mainly a subclinical disease, when the nasal cavity is affected, epistaxis, mucopurulent nasal discharge, dyspnea, and facial distortion may occur. This report describes a case of cryptococcosis in a koala where unilateral exophthalmos was the only evident clinical sign and magnetic resonance imaging and computed tomography findings are described.

Atypical chorioretinal coloboma in a Golden Retriever: a retinographic, fluoroangiographic, and optical coherence tomography study.

Purpose: To report a case of canine atypical chorioretinal coloboma where ophthalmoscopic, fluoroangiographic and optical coherence tomography characteristics are described.

Animal Studied: A 2-year-old Golden Retriever dog in which routine ophthalmoscopic examination allowed diagnosis of a posterior coloboma on the left eye.

Procedures: Retinography, fluorescein angiography, and optical coherence tomography were performed to characterize the lesion of the left fundus.

Central corneal thickness and intraocular pressure in captive black-footed penguins (Spheniscus dermersus).

Objective: To determine the central corneal thickness (CCT) by ultrasonic pachymetry and the effect of these values on the measurements of intraocular pressures (IOP) with rebound tonometry (TonoVet(®) ) in a captive flock of black-footed penguins (Spheniscus dermersus). Variations in CCT by age and weight, and variations in IOP by age were compared.

Animal Studied: Both eyes of 18 clinically normal black-footed penguins (Spheniscus dermersus) were used.

Conjunctival squamous cell carcinoma in a reindeer (Rangifer tarandus tarandus).

An 8-year-old female adult reindeer (Rangifer tarandus tarandus) was referred to the Veterinary Hospital of Madrid for evaluation of a conjunctival mass on the left eye which had been present for about 2 months. A surgical excision was performed and biopsy material submitted for light microscopic evaluation which confirmed the diagnosis of conjuctival squamous cell carcinoma. Nuclear p53 immunolabeling was found in 52% of the neoplastic cells.

Surgical correction of a corneal perforation in an alpaca (Lama pacos).

Likely because of trauma, an adult alpaca (Lama pacos) sustained a corneal perforation with a prolapsed iris. Because of the severity of the lesion, a pedicle conjunctival graft was performed. The structural integrity of the cornea was reestablished, and 10 mo postoperatively, the affected eye appeared to have good vision and only a small corneal scar remained.
