OBJECTIVE To determine if congenital stationary night blindness (CSNB) exists in the Miniature Horse in association with leopard complex spotting patterns (LP), and to investigate if CSNB in the Miniature Horse is associated with three single nucleotide polymorphisms (SNPs) in the region of TRPM1 that are highly associated with CSNB and LP in Appaloosas.… (More)
Four alpacas, 2 wk to 1 y of age, were diagnosed with congenital atresia of the nasal puncta of the nasolacrimal duct. Dacryocystorhinography confirmed and localized the atresia. All animals were treated successfully by surgical creation of nasal puncta and patency was ensured by placement of a surgical stent for several weeks.
PURPOSE To describe the clinical, histological, and immunohistochemical manifestations of canine necrotizing scleritis. METHODS A retrospective examination of the clinical records and samples of ocular tissues from five dogs with a histological diagnosis 'necrotizing scleritis' was completed. Archived, formalin-fixed, paraffin-embedded samples and two… (More)
A congenital peripheral primitive neuroectodermal tumor of the hand demonstrating aggressive behavior by rapid growth and ulceration, as well as early diffuse metastasis is presented. Management consisted of below-elbow amputation and chemotherapy. Despite the tumor's initial response, intracranial metastases occurred 7 months later. The patient died… (More)
A group of beef cattle in eastern Alberta was investigated due to sudden onset of blindness after grazing on standing corn in mid-winter. Fumonisin-producing Fusarium spp. were isolated from the corn. Blindness was due to an optic nerve degeneration suspected to be secondary to fumonisin mycotoxin.
OBJECTIVE The objective of this study is to investigate the structural and functional ocular changes that develop in turkeys exposed to a photoperiod of 23 h of light (23L) compared with a photoperiod of 14 h of light (14L). PROCEDURES Ten-day-old Nicholas heavy strain poults were exposed to either a 14L or 23L photoperiod. Between 16 and 18 weeks of age,… (More)
This study assessed the value of polymerase chain reaction (PCR) for making a diagnosis of feline herpesvirus (FHV-1) infection, and for differentiating this from Chlamydophila felis and Mycoplasma spp. infection in a clinical setting in Canada. We compared the frequency of positive FHV-1 PCR test results from 48 clinical cases of ocular disease in cats… (More)
The objectives of this study were to determine the demographics of horses with equine recurrent uveitis (ERU) presenting to the Western College of Veterinary Medicine and to describe and compare the prognosis of ERU in the Appaloosa with that in other breeds. Horses diagnosed with ERU by a veterinary ophthalmologist between 2002 and 2015 were included. Eye… (More)
This case report describes the clinical manifestations and ocular pathology of an intraocular sarcoma in a spayed female 7-year-old rabbit that developed clinical signs consistent with phacoclastic uveitis at 6 months of age, which was left untreated for most of the next 6 years. Ophthalmologic examination confirmed pupillary occlusion, aqueous flare,… (More)
Methicillin-resistant Staphylococcus aureus (MRSA) causes severe infections with only few effective antibiotic therapies currently available. To approach this challenge, chemical entities with a novel and resistance-free mode of action are desperately needed. Here, we introduce a new hydroxyamide compound that effectively reduces the expression of… (More)
