Atypical chorioretinal lesions in Siberian Husky dogs with primary angle-closure glaucoma: a case series.

Background: A number of etiologies for different canine chorioretinal lesions have been proved or suggested but some fundic lesions remain unclear in terms of an etiologic diagnosis, treatment options and prognosis. The purpose of this case series is to describe atypical chorioretinal lesions observed in dogs with primary angle-closure glaucoma (PACG).

Case Presentation: Two spayed-female Siberian Huskies (3- and 4-year-old) and one Siberian Husky/Australian Shepherd mixed breed dog (11-month-old) that had multifocal depigmented retinal lesions and PACG were included.

Non-invasive optical coherence tomography angiography: A comparison with fluorescein and indocyanine green angiography in normal adult dogs and cats.

Purpose: While the retinal vasculature can be assessed by simple funduscopy, a more detailed assessment can be performed by conventional angiography using dyes such as fluorescein or indocyanine green. The development of optical coherence tomography angiography (OCT-A) allows a non-invasive detailed examination of posterior segment vasculature. The purpose of this prospective study was to compare imaging of posterior segment vasculature in normal dogs and cats using OCT-A, fluorescein angiography (FA), and indocyanine green angiography (ICGA).

Localized alopecia and suppression of hypothalamic-pituitary-adrenal (HPA) axis in dogs following treatment with difluprednate 0.05% ophthalmic emulsion (Durezol®).

Background: Despite the common use of topical ophthalmic corticosteroids in dogs, detailed reports on systemic and dermatologic adverse effects are limited.

Results: Nine purpose-bred research Beagles were treated with difluprednate 0.05% ophthalmic emulsion in one or both eyes 2-3 times daily.

Aqueous Angiography in Normal Canine Eyes.

Purpose: To conduct aqueous angiography (AA) using a clinically applicable technique in normal dogs and to compare findings to intravenous scleral angiography (SA).

Use of 3-dimensional printing in surgical exploration of a nasolacrimal duct obstruction in a dog.

A 1.5-year-old spayed female English setter dog was presented because of mucopurulent discharge emanating from the left medial canthal region of 8-months duration despite medical management and repeated nasolacrimal flushing. Dacryocystorhinography demonstrated obstruction at the level of the lacrimal sac.

Comparison of angiographic dyes and injection techniques for ocular anterior segment angiography in horses.

OBJECTIVE To assess and compare 2 injection techniques for conducting ocular anterior segment indocyanine green angiography (ASICGA) and sodium fluorescein (SF) angiography in horses. ANIMALS 3 healthy adult female horses (age range, 19 to 25 years). PROCEDURES Horses were sedated, jugular catheters were placed, and manual restraint was used to ensure proper positioning for the angiography procedure.

Dorsally located corneal dermoid in a cat.

Case Summary: A 2-month-old, male kitten was presented for evaluation of unilateral blepharospasm and epiphora involving the right eye. Ocular examination revealed conjunctivitis, a superficial corneal ulcer, reflex anterior uveitis and a haired mass within the dorsal cornea of the right eye. The mass was subsequently removed surgically via a lamellar keratectomy.

Comparison of indocyanine green and sodium fluorescein for anterior segment angiography of ophthalmically normal eyes of goats, sheep, and alpacas performed with a digital single-lens reflex camera adaptor.

OBJECTIVE To compare results of anterior segment angiography of ophthalmically normal eyes of goats, sheep, and alpacas performed by use of indocyanine green (ICG) and sodium fluorescein (SF). ANIMALS 10 female goats (mean ± SD age, 6.8 ± 1.

Corneal thickness of eyes of healthy goats, sheep, and alpacas manually measured by use of a portable spectral-domain optical coherence tomography device.

OBJECTIVE To determine corneal thickness of eyes of healthy goats, sheep, and alpacas by use of a portable spectral-domain optical coherence tomography (SD-OCT) device and evaluate intraoperator reliability for measurements. ANIMALS 11 female goats, 10 female sheep, and 11 (4 males and 7 females) alpacas. PROCEDURES Each animal was sedated, and gentle manual restraint was used to ensure proper positioning of the head and globe.

Use of indocyanine green and sodium fluorescein for anterior segment angiography in ophthalmologically normal cats.

Objective: To assess and compare results of anterior segment angiography of ophthalmologically normal cats following IV injection with indocyanine green and sodium fluorescein dyes.

Animals: 10 client-owned cats.

Procedures: Anterior segment angiography was performed in anesthetized cats following administration of 0.

Fluorescein angiography of the canine posterior segment using a dSLR camera adaptor.

Purpose: To describe the use of a digital single lens reflex (dSLR) camera adaptor for conducting posterior segment fluorescein angiography in canines.

Methods: Ten beagle dogs free of ocular and systemic disease were used. All dogs received maropitant citrate (1.

Reflex-free digital fundus photography using a simple and portable camera adaptor system. A viable alternative.

Purpose: To describe a digital single lens reflex (dSLR) camera adaptor for posterior segment photography.

Method: A total of 30 normal canine and feline animals were imaged using a dSLR adaptor which mounts between a dSLR camera body and lens. Posterior segment viewing and imaging was performed with the aid of an indirect lens ranging from 28-90D.

Anterior and posterior segment photography. An alternative approach using a dSLR camera adaptor.

Purpose:   To describe a novel digital single lens reflex (dSLR) camera adaptor for anterior and posterior segment photography.

Methods:   The adaptor was used to evaluate canine, feline, and equine patients presenting to Tufts Ophthalmology service. Anterior segment imaging was conducted with the adaptor mounted between a dSLR camera body (Canon 7D) and a macro lens (Canon EF-S 60mm/f2.

Effect of topical 0.03% flurbiprofen and 0.005% latanoprost, alone and in combination, on normal canine eyes.

Objective: Evaluate the influence of topically applied flurbiprofen 0.03% and latanoprost 0.005%, alone or in combination, in normal canines.

Corneal epithelial inclusion cyst in a Llama.

A 13-year-old, female Llama presented for evaluation of a limbal based corneal mass involving the OD of 4 months duration. The mass was excised en bloc by a nonpenetrating keratectomy, followed by placement of a conjunctival advancement flap covering the keratectomy site. The mass was submitted for histological evaluation.

Feline conjunctival hemangioma and hemangiosarcoma: a retrospective evaluation of eight cases (1993-2004).

The purpose of this retrospective study was to evaluate feline primary conjunctival vascular tumors of endothelial origin. Eight cases (six hemangiomas, two hemangiosarcomas) from a collection of 3460 feline submissions between 1993 and 2004 were evaluated using routine hematoxylin and eosin (H&E). Signalment, location, size, duration, epithelial pigmentation, margins, adjuvant therapy, outdoor activity, and geographic location, comparing ultraviolet (UV) radiation levels by state, were recorded.

Canine conjunctival hemangioma and hemangiosarcoma: a retrospective evaluation of 108 cases (1989-2004).

Canine conjunctival tumors of vascular endothelial origin are common, although under-reported. The purpose of this study was to evaluate the epidemiology of and potential risk factors for these tumors. This study evaluated 108 cases (70 hemangiomas, 38 hemangiosarcomas) from 8300 canine submissions between 1989 and 2004.
