Orbital compartment syndrome (OCS) is described in humans as an acute rise in intraorbital pressure following a severe and rapidly evolving orbital affection. It includes orbital oedema, haemorrhage or infection causing a marked reduction in local blood perfusion, and severely affecting the orbital neurovascular structures. If not promptly recognised and treated, it results in irreversible blindness. It is one of the rare ophthalmic surgical emergencies, requiring lateral canthotomy and cantholysis. This case report describes two canine cases of complex orbital, periorbital and facial abscesses resulting in OCS and permanent unilateral blindness diagnosed by ultrasonography, computed tomography and electroretinography.

Background Equine recurrent uveitis (ERU) has been associated with Leptospira spp. infection. No information exists concerning the prevalence of Leptospira‐associated ERU in Belgium and about the sensitivity of detection of Leptospira in different ocular media. Objectives To establish the prevalence of intraocular Leptospira spp. in ERU‐affected and healthy eyes of horses examined at the Equine Clinic of the University of Liège by real‐time PCR and to compare the results of the aqueous and vitreous humour of the same eye. Study design Cross‐sectional. Methods Sixty‐six eyes from 59 client‐owned horses with a diagnosis of equine recurrent uveitis (ERU‐group) were studied from May 2015 to December 2017. Fifty healthy eyes from 28 euthanised horses for unrelated reasons examined during the same period were included in the control group. Intraocular fluids (aqueous and/or vitreous humours) from ERU‐affected eyes were sampled and analysed by real‐time PCR for Leptospira spp. Aqueous and vitreous humours from the control group were processed in the same way. Results Both groups were comparable regarding age, sex, eye sampled (OS/OD), humours sampled (aqueous/vitreous humour) but not regarding breeds, with an over‐representation of Warmbloods and Appaloosas in the ERU‐group. The prevalence of Leptospira spp. was 30.3% (20/66 eyes) in the ERU‐group. Leptospira spp. DNA was identified in 11 aqueous and 17 vitreous humours with eight horses testing positive in both humours, nine horses testing positive for vitreous humour alone and third horses for aqueous humour alone. The phi‐correlation between aqueous and vitreous humour Leptospira‐PCR results is 0.47 suggesting a low association. All the control eyes were negative. Main limitations The diagnostic method selected for this study (lipL32 qPCR) did not allow identification of the serovars. Conclusions Leptospirosis is a potential cause of ERU in Belgium. Testing both intraocular media is advised whenever possible. [less ▲]

La rétinopathie hypertensive est fréquente chez le chat âgé atteint d’hypertension artérielle. Les principales lésions oculaires sont des hémorragies rétiniennes et/ou des décollements de rétine pouvant conduire à une cécité parfois brutale. Les démarches diagnostiques et thérapeutiques doivent être rigoureuses afin de stabiliser rapidement les lésions, la restauration de la vision restant possible, mais exceptionnelle. Le traitement antihypertenseur est souvent mis en place en urgence et la prévention de l’apparition d’une hypertension artérielle reste le meilleur moyen d’éviter cette situation. [less ▲]

A six-month-old alpaca was presented to the veterinary teaching hospital of the University of Liège (Belgium) with a bilateral cataract. A decision was made to perform bilateral cataract surgery after an ocular ultrasound and electroretinogram were performed to assess the posterior segment and retinal function, respectively. As a premedication, the alpaca received xylazine, butorphanol and midazolam intramuscularly. Anaesthesia was induced subsequently with ketamine and midazolam intravenously and maintained with isoflurane on oxygen/air mixture. The alpaca was mechanically ventilated during surgery. Neuromuscular blockade was induced and maintained with cis-atracurium intravenously. The dose of cis-atracurium was permanently adapted using a peripheral nerve stimulator. This case report brings new knowledge regarding the use and dosage of cis-atracurium in alpacas. [less ▲]

The objective of this prospective study was to investigate the success rate, practicality and complications of a new perilimbal pocket technique for the replacement of prolapsed nictitans gland in 30 dogs (44 eyes). A first incision was made in the bulbar conjunctiva, 2-3 mm from and parallel to the infero-nasal limbus, a second incision on the bulbar aspect of the nictitating membrane (NM), 2-3 mm parallel to the free edge. The gland was returned to its normal position by suturing the subconjunctival tissues of the NM to the episcleral tissues, using four to six interrupted horizontal mattress sutures. The English bulldog, Neapolitan mastiff, great dane and American cocker spaniel were commonly presented. Nictitans gland prolapse occurred prior to one year of age in 83.3 per cent of dogs, and unilaterally in 15 patients. The procedure was easy to perform, and had a 90.9 per cent success rate, with minimal complications. The median duration of follow-up, conducted by ophthalmic examination or telephone contact with the owners, was 21.5 months. Tear production and ocular health were not affected in 17 eyes with at least six months follow-up. There was a statistically significant increase between preoperative and postoperative Schirmer tear test-1 measurements. [less ▲]

REASONS FOR PERFORMING STUDY: There is a clinical impression that tetracaine hydrochloride (THCl) eyedrops is a suitable topical anaesthetic in horses. OBJECTIVE: To determine the duration of corneal anaesthesia following instillation of multiple doses and 2 concentrations of THCl in 10 healthy horses. METHODS: The corneal touch threshold (CTT) was determined, in both eyes, before (basal CTT) and after application of one drop of 0.5% THCl, 2 drops at a 1 min interval of 0.5% THCl or one drop of 1% THCl. CTT was measured in mm every 5 min until complete recovery of the basal CTT. Treatments were separated by an interval of at least one week. RESULTS: Corneal sensitivity was significantly reduced from baseline values for 30, 60 and 50 min after application of one drop of 0.5% THCl, 2 drops of 0.5% THCl and one drop of 1% THCl, respectively. Mean maximal anaesthetic effects, corresponding to a CTT of 0 mm, lasted 5.5, 16 and 15.25 min and maximal anaesthetic effect was present in 55, 90 and 80% of eyes, 5 min after application of one drop of 0.5% THCl, 2 drops of 0.5% THCl and one drop of 1% THCl, respectively. CONCLUSIONS: The application of a second drop or the use of more concentrated eyedrops significantly increases duration of both anaesthesia and maximal anaesthetic effect. POTENTIAL RELEVANCE: Duration of corneal anaesthesia following tetracaine instillation was established enabling a better use when performing diagnostic and therapeutic procedures. Comparison of tetracaine with other ocular anaesthetics needs to be published in the future. [less ▲]

REASONS FOR PERFORMING STUDY: Tetracaine hydrochloride (THCl) has been reported to cause irritation in dogs. In man, some topical anaesthetics have been shown to disrupt the tear film. Tear break-up time (TBUT) is a useful test allowing an assessment of the quality of the precorneal tear film. Only one TBUT value has been reported in horses with no information on the technique used. OBJECTIVES: To provide a method for performing the TBUT in horses and to report any side effects of a single application of THCl in clinically normal horses, particularly on the stability of the tear film. METHODS: In Study 1, one drop of 0.5 or 1% THCl was applied to one eye of 20 horses divided in 2 groups. Treated eyes were assessed for the development of side effects 2.5 and 5 min after treatment. In Study 2, the TBUT was measured in both eyes of 2 groups of 10 horses, before and 2.5 and 5 min after, instillation of one drop of either 0.5 or 1% THCl. RESULTS: No animals developed any ocular side effect after instillation. Basal TBUT was 8.3±1.3 s. TBUT decreased from baseline 5 and 2.5 min after application of one drop of 0.5% THCl and one drop of 1% THCl, respectively. CONCLUSIONS: A technique to measure the TBUT in healthy horses is described and normal range values that could be used as a reference were obtained. POTENTIAL RELEVANCE: THCl is well tolerated in horses but lowers the TBUT. [less ▲]

Les tumeurs mélanocytaires sont plus fréquentes chez le chien que chez le chat. Les mélanomes et les mélanocytomes requièrent un examen approfondi afin d’établir la conduite à tenir. En règle générale, dans les deux espèces, les mélanomes palpébraux présentent un bon pronostic s’ils sont excisés au plus tôt, même si des récidives sont toujours possibles. Si les mélanomes conjonctivaux semblent être agressifs dans les deux espèces, en revanche, les mélanomes épibulbaires ont tendance à être bénins et à progresser très lentement. Enfin, c’est chez le chat que le pronostic est le plus mauvais lors de mélanome intra-oculaire, à la fois pour l’œil et pour l’animal [less ▲]
