The study aimed to determine the impact of drop size on tear film pharmacokinetics and assess important physiological parameters associated with ocular drug delivery in dogs. Two separate experiments were conducted in eight healthy Beagle dogs: (i) Instillation of one drop (35 μl) or two drops (70...

A novel supra-temporal technique for retrobulbar anaesthesia in dogs is described and compared to the inferior temporal palpebral approach. Supra-temporal and inferior temporal palpebral retrobulbar injections were performed in 20 orbits of canine cadavers. Distribution of injected contrast medium...

Tissue fragility, skin hyperextensibility and joint hypermobility are defining characteristics of Ehlers-Danlos syndrome (EDS). Human EDS is subclassified into fourteen types including dermatosparactic EDS, characterized by extreme skin fragility and caused by biallelic ADAMTS2 mutations. We report ...

Purpose: To explore the effects of chronic, uncontrolled glaucoma on pressure sensitivity in dogs before and after enucleation of the painful globe. Methods: Client-owned dogs undergoing enucleation for chronic glaucoma with no other sources of pain were enrolled. Normal dogs of similar breeds and...

A simple method of measuring the length of the fully stretched palpebral fissure by using slightly modified sliding calipers was tested in 423 animals, including 386 dogs and 37 cats with both normal and abnormal apposition of the lids to the globe. The mean palpebral fissure length (PFL) was...

A case of congenital lacrimal cyst or dacryops of the lacrimal gland in an 8-month-old Neapolitan Mastiff dog is reported. The dog presented with a swelling dorsolateral to the left globe, which had been present since birth. In addition, hyperplasia and prolapse of the superficial gland of the left ...

Objective: To describe selected ophthalmic tests and anatomical features of eyes of crab-eating foxes (Cerdocyon thous) and maned wolves (Chrysocyon brachyurus). Animals studied: Six crab-eating foxes (12 eyes), eight maned wolves (16 eyes). Procedures: Intramuscular and/or inhalatory anesthesia,...

Objective: To describe ocular anatomical features and to determine tear production and tonometry in normal anesthetized ring-tailed coati (Nasua nasua). Animals: Eight male and seven female ring-tailed coatis (30 eyes) were evaluated, with ages ranging from 7 months to 10 years old. Procedures The...

A 3.5-year-old male Neapolitan Mastiff was presented with an obstructed visual axis because of excessive facial skin folds, brow droop, macroblepharon, upper eyelid entropion and lower ectropion-entropion. To address these major defects a technique was performed which combines rhytidectomy with...
