Animals: Sixty-four equids presenting with FNP between July 2000 and April 2019.

Ocular and periocular hemangiosarcoma in six horses.

Objective: To determine the characteristics of and prognosis for ocular and periocular hemangiosarcoma in horses.

Animal Studied: Six horses treated for ocular or periocular hemangiosarcoma.

Procedure: A retrospective review of medical records from 2007 to 2015 was performed to identify horses with a histologic diagnosis of ocular or periocular hemangiosarcoma.

Corneal sensitivity and tear production in 108 horses with ocular disease.

Purpose: To compare corneal sensitivity and tear production in horses with keratitis to horses with other ocular disease.

Method: Retrospective medical record review was used to identify equine patients presented during a 1-year period for an ocular complaint who had Schirmer Tear Test (STT) or Corneal Touch Threshold (CTT) measured. Variables studied included patient age and sex; affected eye; category of presenting ocular complaint (keratitis vs.

Interval prevalence of and factors associated with colic in horses hospitalized for ocular or orthopedic disease.

OBJECTIVE To determine interval (1-year) prevalence of and factors associated with colic in horses hospitalized for ocular or orthopedic disease. DESIGN Cross-sectional study. ANIMALS 105 horses with ocular disease and 197 horses with orthopedic disease admitted to a veterinary teaching hospital between July 1, 2011, and June 30, 2012.

Corneal edema in four horses treated with a superficial keratectomy and Gundersen inlay flap.

Objective: To describe the clinical presentation, treatment, and outcome of four horses with severe corneal edema caused by suspected endothelial disease treated with a superficial keratectomy and Gundersen inlay flap and to determine whether this procedure (i) reduces corneal edema, (ii) reduces ocular pain, (iii) eliminates recurrent corneal ulceration, and (iv) improves vision in these horses.

Animals Studied: Four horses met inclusion criterion of (i) diagnosis with endothelial disease by a board-certified veterinary ophthalmologist and (ii) surgical treatment with a superficial keratectomy and Gundersen inlay flap.

Procedure: Retrospective medical record review of included horses was used to determine breed, age and sex of included horses, as well as details of medical and surgical therapy, and visual outcome.

Porcine urinary bladder extracellular matrix grafts (ACell Vet® Corneal Discs) for keratomalacia in 17 equids (2012-2013).

Objective: To describe the clinical course, outcomes, and complications associated with use of commercially available porcine urinary bladder extracellular matrix (ECM) grafts (ACell Vet(®) Corneal Discs) in equid patients with keratomalacia, and to evaluate the efficacy of ECM grafts as a viable alternative to other biomaterials for corneal grafting in equid patients.

Animals: Sixteen horses and one donkey (17 eyes) with unilateral keratomalacia severe enough to warrant surgical repair between August 2012 and September 2013.

Procedure: Retrospective medical record review to identify equid patients meeting inclusion criteria of (i) diagnosis with keratomalacia severe enough to warrant surgical repair and (ii) surgical repair with an extracellular matrix graft.

Characterization and outcome following excision of masses in the nictitating membranes of horses: 50 cases (1998-2012).

Objective: To determine the histologic findings associated with masses in the nictitating membranes (third eyelids) of horses and to identify prognostic factors associated with recurrence and the outcome.

Design: Retrospective case series.

Animals: 50 horses with masses in a third eyelid.

Toggenburg Orbivirus, a new bluetongue virus: initial detection, first observations in field and experimental infection of goats and sheep.

A novel bluetongue virus termed "Toggenburg Orbivirus" (TOV) was detected in two Swiss goat flocks. This orbivirus was characterized by sequencing of 7 of its 10 viral genome segments. The sequencing data revealed that this virus is likely to represent a new serotype of bluetongue virus [Hofmann, M.

Low-frequency modulation of distortion product otoacoustic emissions in humans.

Low-frequency modulation of distortion product otoacoustic emissions (DPOAEs) was measured from the human ears. In the frequency domain, increasing the bias tone level resulted in a suppression of the cubic difference tone (CDT) and an increase in the magnitudes of the modulation sidebands. Higher-frequency bias tones were more efficient in producing the suppression and modulation.
