A Post-Operative Follow-Up of an Endangered Saltwater Fish Lensectomy for Cataract Management in a Public Aquarium: A Case Series.

Mature cataracts can be a life-threatening condition in fish as it may result in anorexia. Lens extraction has been previously described in fish, but the long-term outcome of this procedure has not been evaluated. Eleven captive-bred adult fish housed in a public aquarium presented with unilateral ( = 3/11) or bilateral ( = 8/11) mature cataracts.

Morphological Evaluation of Transscleral Laser Retinopexy in Rabbits: Comparison of Optical Coherence Tomography and Histologic Examinations.

Transscleral retinopexy is a preventive technique used against retinal detachment. Fundus examination can allow the monitoring of morphological retinal changes in the progression of photocoagulation lesions, without offering details on the morphological changes by the retinal lesion. The aim of the study was to assess the progression of photocoagulation lesions induced by transscleral retinopexy (840 nm diode laser), by comparing the optical coherence tomography (OCT) and histological images over a period of six weeks on eight pigmented New Zealand healthy rabbits (four males and four females; n = 16 eyes) All rabbits underwent transscleral retinopexy on their left eye on day 0 (D0).

Electroretinography, Ocular Ultrasonography, and Phacoemulsification of Bilateral Cataracts in Two Juvenile Loggerhead Sea Turtles () of the Mediterranean Region.

Bilateral cataracts were diagnosed in two rescued juvenile, immature loggerhead sea turtles (), weighing 1.65 and 1.7 kg.

Optical Coherence Tomography: A Review of Current Applications in Veterinary Ophthalmology.

Normative standards for healthy animal structures have been established by optical coherence tomography (OCT). OCT has been used in animal studies to characterize more precisely ocular lesions, identify the origin of the affected layer, and eventually provide a curative treatment. To acquire a high image resolution, several challenges must be overcome when performing an OCT scan on animals.

Effect of topical cyclopentolate alone or combined with phenylephrine in healthy horses.

Objective: Evaluate the effect of repeated doses of topical 1% cyclopentolate hydrochloride alone and in combination with topical 2.5% phenylephrine on pupil diameter (PD), tear production (STT-1), intraocular pressure (IOP), digestive function (gut motility and feces production), and heart rate (HR).

Animal Studied: Six healthy mares.

Stability of epidermal growth factor, fibronectin, and alpha-2-macroglobulin in canine serum under different storage conditions.

The objective of this study was to assess whether concentrations of epidermal growth factor (EGF), fibronectin, and alpha(α)-2-macroglobulin in canine serum remain stable under different storage conditions. Serum was obtained from 10 adult dogs and stored for 7 d at room temperature (RT) and at 4°C and for 1, 3, and 6 mo at -20°C. Bacterial cultures of serum were carried out after 7 d at 4°C and at RT.

Retrobulbar malignant peripheral nerve sheath tumor in a golden retriever dog: A challenging diagnosis.

A 9-year-old golden retriever dog was diagnosed with a left retrobulbar mass. Fine-needle aspirations and incisional biopsies resulted in discordant diagnoses: myxosarcoma/myxoma or rhadomyosarcoma, respectively. Immunohistochemistry following exenteration allowed definitive diagnosis of malignant peripheral nerve sheath tumor with fibromyxomatous differentiation.

Congenital cataract in 1-day-old French Mulard ducklings.

Ocular opacity, associated with reluctance to move and inability to feed properly, was observed in approximately 1% of all newly hatched females from several related flocks of Mulard ducks. A 5-week follow-up study of 10 1-day-old affected females was performed, and they were compared with 10 control animals. Clinical, ocular and ultrasonographic examinations, and a complete necropsy of two animals per group with histological examination of the eye, were performed weekly.

Surgical repair of deep melting ulcers with porcine small intestinal submucosa (SIS) graft in dogs and cats.

Purpose: To evaluate the efficacy of using a porcine small intestinal submucosa (SIS) graft for the surgical repair of deep melting ulcers in dogs and cats.

Methods: Two cats and five dogs presented with deep and large melting ulcers of the cornea. In each case, the necrotic and collagenolytic tissue of the cornea was removed by keratectomy.

Ocular findings in two colonies of gray mouse lemurs (Microcebus murinus).

Objective: To determine the incidence and describe the characteristics of cataracts and other ocular lesions found in two colonies of gray mouse lemurs (Microcebus murinus).

Animals Studied: A total number of 218 mouse lemurs (age range: 4 months-11 years) were included in this study. All individuals were property of the Muséum National d'Histoire Naturelle (France), and were housed either in Paris (colony #1: 75 animals examined), or in Brunoy (colony #2: 143 animals).
