A well-differentiated invasive ocular squamous cell carcinoma (OSCC) localized in the conjunctiva and medial peribulbar region, including the third eyelid, was diagnosed in the left eye of a 5-year-old Holstein cow causing ocular pain. Marginal resection of the neoplastic mass was performed with ...

Objective: To evaluate the effect of retrobulbar block during orbital exenteration on heart rate variability (HRV). Materials and methods: Fourteen adult cows with ocular squamous cell carcinoma were used. Ocular exenteration is performed under multimodal anesthesia. The cows were sedated (xylazine ...

This article describes the case of a 5-year-old Holstein-Friesian dairy cow that was evaluated by a veterinary practitioner for a 30-day history of unilateral exophthalmos. The cow later developed lameness, progressive weight loss, and pelvic limbs paresis, leading to persistent sternal recumbency. ...

The aims of the study included evaluating the effects of levobupivacaine combined with cisatracurium on akinesia and mydriasis when administered by peribulbar injection, and evaluating if the chosen dose of cisatracurium is enough to avoid the use of systemic neuromuscular blockade in cats. The...

Objective: To describe a novel in-plane ultrasound (U/S)-guided temporal approach to peribulbar block in dogs. Study Design: Prospective experimental cadaver study. Animals A group of 10 Beagle cadavers. Methods: After describing the U/S anatomy, peribulbar injection was performed bilaterally in 10 ...

Objective: To describe a contrast medium distribution pattern after peribulbar injection in cadavers. Study design A cadaveric study. Animals: A group of eight male dogs and four canine cadaver heads. Methods: In phase 1, ultrasound-guided peribulbar injections (1.0 mL dye) were performed in four...

Objective: To compare the peribulbar injectate distribution and probability of regional anaesthesia of four peribulbar anaesthetic techniques in equine cadavers. Study design: Prospective experimental cadaver study. Animals: A total of 12 isolated equine cadaver heads and 24 eyes. Methods: The 24...

This paper discusses the use of a peribulbar local block with bupivacaine in a rabbit presenting for enucleation and represents an alternative locoregional technique to a retrobulbar block, which is challenging to perform in rabbits due to the presence of a venous sinus behind the globe. A ...

Objective - To compare effectiveness and complications associated with peribulbar and retrobulbar anesthesia with bupivacaine in cats. Animals - 6 healthy adult cats. Procedures - Cats were sedated with dexmedetomidine and received a peribulbar injection of 0.5% bupivacaine (1.5 mL), iopamidol (0.5 ...

Objective: To document a case of limbal squamous cell carcinoma (SCC) in an adult Black Baldy cow treated with photodynamic therapy (PDT) as an adjunctive therapy following surgical excision. Animals Studied: One privately owned 8-year-old female, entire, Black Baldy cow. Procedures: A complete...
