OBJECTIVE To compare central corneal thickness (CCT) measurements obtained from normal canines using a spectral-domain optical coherence tomography device (SD-OCT) and an ultrasonic pachymeter. ANIMALS Fifteen clinically normal dogs. PROCEDURES Dogs were briefly anesthetized with propofol. Central corneal thickness measurements were obtained from both(More)
We present a series of three American Bulldogs with clinical signs of glaucoma and intraocular inflammation accompanied by bilateral uveal cysts and abnormal gonioscopic findings. All dogs proved refractory to medical management and were enucleated. Histopathologic findings were similar in all three and included significant preiridal fibrovascular membranes(More)
The purpose of this study was to manually measure corneal thickness in canine eyes using a spectral-domain optical coherence tomography (SD-OCT) device and to assess intra- and inter-observer reliability of this technique. Twenty healthy dogs with a mean age of 4.7 y were examined. A 6-mm corneal pachymetry protocol was carried out by 1 operator using 1(More)
We present a report describing use of a 360-degree conjunctival graft for management of progressive keratomalacia refractory to medical treatment in a 5-month-old American Cocker Spaniel. In the dog of this report, the extension of melting to nearly the entire corneal surface limited surgical options. Following surgery and later resection of the graft, the(More)
PURPOSE To describe anterior segment fluorescein angiography (ASFA) of the normal feline eye using a digital single-lens reflex (dSLR) camera adaptor. ANIMALS Ten cats free of ocular and systemic disease were evaluated. METHODS All cats received maropitant citrate (1.0 mg/kg SQ) and diphenhydramine (2.0 mg/kg SQ) 20 min prior to anesthesia using(More)
PURPOSE  To describe histologic anterior segment changes in eyes affected with primary lens displacement (PLD) and secondary glaucoma. METHODS  Histologic sections stained with H&E from canine eyes enucleated because of PLD and secondary glaucoma were examined. RESULTS  Thirteen eyes from 12 patients were evaluated. Four dogs were castrated males and eight(More)
PURPOSE  To describe anterior segment fluorescein angiography (ASFA) of the normal canine eye using two different sedation/anesthetic protocols and a digital single lens-reflex (dSLR) camera adaptor. METHODS Dogs free of ocular and systemic disease were used for this study. Dogs received maropitant citrate (1.0 mg/kg SQ) and diphenhydramine (2.0mg/kg SQ)(More)
OBJECTIVE The aim of the study was to evaluate the efficacy, outcome, and complications following penetrating sclerokeratoplasty and frozen homologous corneoscleral grafting for the management of extensive canine epibulbar melanocytomas. METHODS Medical records of canine patients treated at three different veterinary hospitals between 1999 and 2010 were(More)
CASE DESCRIPTION A 2-year-old Morgan mare was evaluated because of a corneal ulceration. CLINICAL FINDINGS An irregular, deep stromal corneal ulcer in an area of malacia was noted in the left eye. Hypopyon was present in the ventral portion of the anterior chamber with moderate aqueous flare. The nictitating membrane of the left eye had hairs originating(More)
OBJECTIVE To determine the intra and inter-user reliability of central corneal thickness (CCT) measurements obtained using a portable spectral-domain optical coherence tomography (SD-OCT) device in healthy feline eyes. ANIMALS Twenty clinically normal cats. PROCEDURES Gentle manual restraint was utilized for proper animal positioning. Central corneal(More)
