Interexaminer agreement of gonioscopy examinations in dogs using the European College of Veterinary Ophthalmologists Hereditary Eye Diseases grading scheme.

Objective: Prospective observational study with preregistered study protocol to assess interexaminer agreement using the 2022 European College of Veterinary Ophthalmologists Hereditary Eye Disease (ECVO-HED) gonioscopy grading scheme.

Animals Studied: Sixty client-owned dogs presented for gonioscopy as part of the required certification process prior to breeding.

Procedure: Two ECVO diplomates with comparable clinical experience performed gonioscopy with a Koeppe gonioscopy lens and slit-lamp biomicroscope at 10x magnification on all eyes in a randomized fashion.

Manifestations of hypertensive encephalopathy in cats.

Objectives: Hypertensive encephalopathy in cats is an important entity but is underestimated in clinical practice. This could be explained, in part, by non-specific clinical signs. The objective of this study was to characterise the clinical manifestations of hypertensive encephalopathy in cats.

3T high-resolution magnetic resonance imaging, conventional ultrasonography and ultrasound biomicroscopy of the normal canine eye.

Background: Advances in MRI coil technology and increased availability of high-field MRI in veterinary medicine enable the acquisition of images of increasingly high spatial resolution while preserving signal-to-noise ratio.The purpose of the present study was to compare 3T high-resolution magnetic resonance imaging (HR-MRI) with ultrasound (US) and ultrasound biomicroscopy (UBM) in the normal canine eye, to assess its potential to depict normal ocular anatomy.

Results: HR-MRI was compared with US and UBM in 10 eyes from 10 healthy beagle dogs.

Occurrence of and Typing in Conjunctival and Rectal Samples of Swiss Stray and Pet Cats.

() primarily replicates in feline conjunctival epithelial cells and is an important cause of conjunctivitis in cats. Data on infection rates in stray cats in Switzerland has been missing so far. We performed a qPCR-based -screening on 565 conjunctival and 387 rectal samples from 309 stray and 86 pet cats followed by species identification and typing using the gene , which encodes a polymorphic membrane protein.

Penetrating Keratoplasty in Dogs using Acellular Porcine Corneal Stroma (BioCorneaVet™): A prospective pilot study of five cases.

Objective: This prospective pilot study was conducted to evaluate the outcome of a commercially available corneal stroma substitute, Acellular Porcine Corneal Stroma (APCS), in dogs undergoing penetrating keratoplasty (PK) to restore corneal integrity after having deep ulcers.

Method: Five dogs (1 eye in each dog) underwent a PK using APCS (BioCorneaVet™) as a graft. The surgical procedure and peri- and postoperative treatment were standardized.

The effects of soft cryotherapy on conjunctiva and cornea in isolated pig eyes and comparison with standard liquid nitrogen: A pilot ex vivo study.

Purpose: To evaluate the immediate effects on cornea and conjunctiva of a cryosurgical method based on the application of a dimethyl ether, propane and isobutene solution (DMEPI, Histofreezer ), and of Liquid Nitrogen (LN ; Cry-Ac Cryogun ).

Methods: A total of 52 isolated pig eyes were obtained at the slaughterhouse, preserved for less than one hour in Ringer Lactate and divided into four groups. The first group included eyes treated with two applications of DMEPI in the center of the cornea, the second group eyes treated with DMEPI on the third eyelid's conjunctiva, the third group eyes treated with LN on the third eyelid's conjunctiva and the fourth group included eyes treated with LN on the central cornea.

Use of four-layer porcine small intestinal submucosa alone as a scaffold for the treatment of deep corneal defects in dogs and cats: preliminary results.

Background: To describe the efficacy of four-layer porcine small intestinal submucosa (Vetrix BioSIS plus+) as single scaffold for the treatment of deep corneal lesions in dogs and cats.

Methods: 10 dogs and 3 cats with deep or full thickness corneal defects were treated surgically with BioSIS plus graft. Corneal transparency scores and vision were evaluated.

Use of episcleral cyclosporine implants in dogs with keratoconjunctivitis sicca: pilot study.

Purpose: To describe the use, tolerability, and efficacy of episcleral silicone matrix cyclosporine (ESMC) implants in dogs with keratoconjunctivitis sicca (KCS).

Methods: Retrospective study. ESMC implants (1.

Hormographiella aspergillata keratomycosis in a dog.

A 4-year-old, female, Border Collie was presented to the University of Bern Veterinary Teaching Hospital, because of a corneal lesion of 10 days duration. The axial cornea presented a whitish fluorescein-positive plaque with irregular margins. A diagnosis of keratomycosis was made based on cytology.

Evaluation of the presence of selected viral and bacterial nucleic acids in pericardial samples from dogs with or without idiopathic pericardial effusion.

Many viruses have been identified in pericardial fluid and in tissue samples from humans with pericarditis by means of molecular diagnostics. In canine idiopathic pericardial effusion there is as yet no conclusive evidence to support the involvement of an infectious agent. This study was designed to investigate a possible relationship between idiopathic pericardial effusion in dogs and viruses most commonly encountered in humans affected with viral pericarditis.

Effect of anabolics on bovine granulosa-luteal cell primary cultures.

Granulosa cell tumours are observed with increased frequency among calves slaughtered in Northern Italy. The use of illegal anabolics in breeding was taken into account as a cause of this pathology. An in vitro approach was used to detect the possible alterations of cell proliferation induced by anabolics on primary cultures of bovine granulosa-luteal cells.

Scleral rupture in dogs, cats, and horses.

Objectives: The aim of this retrospective study was to summarize the most frequent clinical signs, ultrasonographic, and histological findings accompanying scleral rupture as a result of blunt trauma in dogs, cats, and horses. ANIMALS STUDIED AND PROCEDURES: Thirty small animals and three horses diagnosed with scleral rupture resulting from blunt trauma. B-mode ultrasonography was performed on 20 animals.

Collie eye anomaly in a mixed-breed dog.

A 5-year-old, mixed-breed dog was presented for tetraparesis. Neurologic alterations included a decreased menace response in both eyes. Therefore, an ophthalmic examination was requested.
