Calcification and osseous metaplasia of the meibomian glands of a horse.

Objective: To report the clinical history, surgical management, and histologic findings of meibomian gland calcification and osseous metaplasia in a horse.

Animal Studied: A 21-year-old Selle Français gelding presented with a 9 months history of blepharitis, blepharospasm, and epiphora affecting the right eye. The horse was diagnosed with meibomianitis and impaction with associated granulomas, but not treated surgically for 6 years.

Preliminary report of postoperative complications of phacoemulsification in Pugs: A multicenter retrospective study of 32 cases.

Objective: To compare complication rates and visual outcomes following phacoemulsification in Pugs versus dogs of other breeds.

Animals Studied: Thirty-two pure-bred Pugs (55 eyes) and 32 dogs of other breeds (56 eyes) undergoing phacoemulsification.

Procedures: Multi-institutional retrospective medical record review of perioperative factors, postoperative complications, and visual outcomes.

Effects of 0.02% netarsudil ophthalmic solution on intraocular pressure of normotensive dogs.

Objectives: To evaluate the effect of QD or BID 0.02% netarsudil ophthalmic solution (Aerie Pharmaceuticals) on intraocular pressure (IOP) in normotensive dogs and to describe any adverse effects.

Animals Studied: Normotensive Labrador retriever dogs were included in this study: 10 received netarsudil in one eye and artificial tears in the contralateral eye QD, and 10 received netarsudil in one eye and artificial tears in the contralateral eye BID.

Glaucoma with Descemet's membrane detachment in five horses.

Purpose: To describe the clinical and histopathologic features of glaucoma associated with Descemet's membrane (DM) detachment in five horses without prior history of intraocular surgery.

Animals Studied: Three Appaloosa horses and two Thoroughbreds were included in this study. The affected horses ranged in age from 16 to 27 years and presented with severe diffuse corneal edema.

Sudden acquired retinal degeneration in dogs: breed distribution of 495 canines.

Purpose: The purpose of this study was to describe breed, age, gender, and weight distribution of dogs affected with sudden acquired retinal degeneration (SARD) and to investigate whether SARD is more common in small breed dogs.

Methods: Medical records of dogs diagnosed with SARD confirmed by an electroretinogram were reviewed. Breed, age, gender, and weight were recorded when available.

Equine Multiple Congenital Ocular Anomalies (MCOA) syndrome in PMEL17 (Silver) mutant ponies: five cases.

Objective: To describe the clinical phenotype and genetics of equine Multiple Congenital Ocular Anomalies (MCOA) syndrome in PMEL17 (Silver) mutant ponies.

Animals Studied: Five presumably unrelated ponies.

Procedures: The ponies were examined under field conditions in their barn by slit lamp biomicroscopy, indirect ophthalmoscopy, and applanation tonometry.

Cataracts: when to refer.

Unique stages of cataract development have been characterized in both human and animal lenses. These lens opacities impair visual acuity and are associated with inflammation. Total lens removal is typically followed by implantation of an artificial intraocular lens to restore vision.

Putative aqueous humor misdirection syndrome as a cause of glaucoma in cats: 32 cases (1997-2003).

Objective: To characterize the clinical and morphologic aspects of aqueous humor misdirection syndrome (AHMS) in cats and provide a hypothesis regarding its pathogenesis on the basis of detailed analysis of affected cats.

Design: Retrospective study.

Animals: 32 cats (40 eyes).

Evaluation of a rebound tonometer for measuring intraocular pressure in dogs and horses.

Objective: To compare intraocular pressure (IOP) measurements obtained with a rebound tonometer in dogs and horses with values obtained by means of applanation tonometry and direct manometry.

Design: Prospective study.

Animals: 100 dogs and 35 horses with clinically normal eyes, 10 enucleated eyes from 5 dogs, and 6 enucleated eyes from 3 horses.

Ocular manifestations of systemic disease in cats.

Systemic feline diseases (parasitic, bacterial, fungal, viral, neoplastic, metabolic, vascular, and immune-mediated) are often associated with ocular symptoms. An ocular examination is an important diagnostic tool and should be part of any physical examination. Conversely, cats afflicted with systemic disease require periodic ocular examinations for prognostic information and to prevent vision threatening complications.

Orbital penetration associated with tooth extraction.

Three cats and 2 dogs were evaluated for ophthalmologic complications associated with tooth extraction procedures. Orbital penetration leading to ocular and, in one case, brain trauma was secondary to iatrogenic injury from a dental elevator. Outcomes included enucleation of the affected eye in 3 cases, and death from brain abscessation in 1 case.

Nonhealing corneal ulcers in cats: 29 cases (1991-1999).

Objective: To compare mean healing times after debridement, debridement with grid keratotomy, and superficial keratectomy in cats with nonhealing corneal ulcers.

Design: Retrospective study.

Animals: 29 cats with 36 nonhealing corneal ulcers.

Experimental measurements of particle retention efficiency of filters used to prevent contamination in respiratory devices.

Objective: Various types of filters have been designed to prevent cross contamination of ventilation and respiratory devices. The aim of this study was to experimentally measure the retention efficiency of four simple filters (antibacterial and antiviral and seven combined filters (antibacterial and antiviral plus heat and water exchangers).

Setting: The respiratory function testing (EFR) central department of a university teaching hospital.
