Assessment of meibomian gland morphology and tear-film lipid layer using noncontact infrared meibography and meibometry, respectively, and tear-film osmolarity in healthy dogs.

Objective: To further investigate quantitative and qualitative tear-film dynamics through tear-film osmolarity, meibometry, meibography, and non-invasive tear-film break-up time and to describe a survey of parameters in normal eyes of healthy non-brachycephalic dogs.

Animals Studied: Thirty-two veterinary hospital staff and student owned dogs between 1 and 7 years with no known comorbidities or ocular disease.

Procedure: Complete ophthalmic examination, tear-film osmolarity (I-PEN® VET), meibometry (Meibometer MB560), meibography, and non-invasive tear-film break-up time (handheld Ocular Surface Analyzer) were performed.

Primary lacrimal gland adenocarcinoma of the third eyelid in a horse.

A 5-year-old Draft Horse gelding presented for evaluation of a large, fleshy, ulcerated third eyelid mass OD of 3 weeks duration. Complete ophthalmic examination, ocular ultrasound and skull radiographs revealed a large soft-tissue mass involving the entire third eyelid OD and extending into the ventral right orbit to the level of the globe equator. No other abnormalities were noted on physical or ophthalmic examination.

Effects of graded doses of propofol for anesthesia induction on cardiovascular parameters and intraocular pressures in normal dogs.

Objective: To determine the effects of graded doses of propofol on cardiovascular parameters and intraocular pressures (IOP) in normal dogs.

Study Design: Prospective, randomized, modified Latin square, cross-over experimental study.

Animals: Eleven adult random-source dogs weighing 20.

Propofol versus thiopental: effects on peri-induction intraocular pressures in normal dogs.

Objective: To determine the effects of propofol or thiopental induction on intraocular pressures (IOP) in normal dogs.

Study Design: Prospective randomized experimental study.

Animals: Twenty-two random-source dogs weighing 19.

Influence of lidocaine and diazepam on peri-induction intraocular pressures in dogs anesthetized with propofol-atracurium.

The purpose of this study was to evaluate the effects on the intraocular pressure (IOP) of lidocaine or diazepam administered intravenously (IV) before induction of anesthesia with propofol-atracurium and orotracheal intubation in normal dogs, as well as the effects on the IOP of lidocaine applied topically to the larynx after induction with propofol-atracurium. We randomly assigned 32 random-source dogs, obtained from municipal pounds, to receive the following: lidocaine, 2 mg/kg IV, with saline, 0.1 mL/kg topically applied to the larynx (LIDOsal); saline, 0.

Effects of ketamine, diazepam, and their combination on intraocular pressures in clinically normal dogs.

Objective: To evaluate the effects of ketamine, diazepam, and the combination of ketamine and diazepam on intraocular pressures (IOPs) in clinically normal dogs in which premedication was not administered.

Animals: 50 dogs.

Procedures: Dogs were randomly allocated to 1 of 5 groups.

Feline corneal disease.

The cornea is naturally transparent. Anything that interferes with the cornea's stromal architecture, contributes to blood vessel migration, increases corneal pigmentation, or predisposes to corneal edema, disrupts the corneas transparency and indicates corneal disease. The color, location, and shape and pattern of a corneal lesion can help in determining the underlying cause for the disease.

Diagnosis and management of chronic corneal epithelial defects (indolent corneal ulcerations).

Chronic corneal epithelial defects (CCEDs; indolent corneal ulcerations) are the most common refractory ulcerations in veterinary medicine and are diagnosed by their classic appearance. CCEDs are superficial ulcerations without stromal involvement and have a nonadherent epithelial border (lip). Fluorescein stain adheres to the exposed stroma and extends below the epithelial border, outlining the epithelial lip.
